OPERATING SAFETY

Before using the generator be sure to read and understand all of the instructions. This equipment was designed for specific applications; DO NOT modify or use this equipment for any application other than which it was designed for. Equipment operated improperly or by untrained personnel can be dangerous! Read the operating instructions and familiarize yourself with the location and proper use of all instruments and controls. Inexperienced operators should receive instruction from someone familiar with the equipment before being allowed to operate or set up the generator. The following points should be practiced at all times:

The area immediately surrounding the generator should be dry, clean, and free of debris.

NEVER start a unit in need of repair.

Make certain the generator is securely fastened to a good earthen ground before use.

NEVER operate unit on a combustible surface.

NEVER operate the generator if any of the following conditions exist during operation: 1. Noticeable change in engine speed. 2. Loss of electrical output. 3. Equipment connected to the generator overheats. 4. Sparking occurs. 5. Engine misfires or there is excessive engine/generator vibration. 6. Protective covers are loose or missing. 7. If the ambient air temperature is above 120F (49C).

Make sure slings, chains, hooks, ramps, jacks, and other types of lifting devices are attached securely and have enough weight-bearing capacity to lift or hold the equipment safely. Always remain aware of the position of other people around you when lifting the equipment.

NEVER operate a unit while tired, distracted, or under the influence of drugs or alcohol.

ENGINE SAFETY

Internal combustion engines present special hazards during operation and fueling! Failure to follow the safety guidelines described below could result in severe injury or death. Read and follow all safety warnings described in the engine operator's manual. A copy of this manual was supplied with unit when it was shipped from the factory.

DO NOT run engine indoors or in an area with poor ventilation. Diesel engine exhaust contains carbon monoxide, a deadly, odorless and colorless gas which, if inhaled, can cause nausea, fainting or death. Only use this unit outside and away from windows, doors, and ventillation equipment.

DO NOT fill fuel tank near an open flame, while smoking, or while engine is running. DO NOT fill tank in an enclosed area with poor ventilation.

DO NOT operate with the fuel tank cap loose or missing.

DO NOT touch or lean against hot exhaust pipes or engine cylinders.

DO NOT clean air filter with gasoline or other types of low flash point solvents.

DO NOT remove engine coolant cap while engine is hot.

DO NOT operate the unit without a functional exhaust system.Prolonged exposure to sound levels in excess of 85 dB(A) can cause permanent hearing loss. Wear hearing protection when working around a running engine.

Keep hands, feet and loose clothing away from moving parts on the generator and engine.

Keep area around exhaust pipes and air ducts free of debris to reduce the chance of an accidental fire.

Batteries contain sulfuric acid which can cause severe injury or death. Sulfuric acid can cause eye damage, burn flesh or eat holes in clothing. Protective eye wear and clothing are necessary when working on or around the battery. Always disconnect the negative (-) battery cable from the corresponding terminal before performing any service on the engine or other components.

ELECTRICAL SAFETY

The unit is powered by a generator driven by a diesel engine. While the engine is running, potentially lethal voltages are present at the 120V Ground Fault Circuit Interrupt (GFCI) receptacles and the 240V twist-lock receptacles located on the control panel, and at the connection lugs and optional cam lock receptacles. Failure to follow the safety guidelines described below could result in severe injury or death.

Only a qualified and licensed electrician should make connections to the generator.

NEVER wash the unit with any high pressure hoses or power washers.

NEVER start the unit under load. The circuit breakers must be in the OFF/O position when starting the unit in Manual mode. The circuit breakers can be in the ON/I position only when started in the Auto mode. A transfer switch must be used in the Auto mode to deflect the load upon startup.

ALWAYS disconnect the NEGATIVE (-) battery cable from the corresponding terminal before performing any service on the engine, generator or any other components. Remove the negative (-) battery cable from the corresponding terminal if the unit is to be stored or transported.

ALWAYS use extreme caution when servicing this unit in damp conditions. Do not service the unit if your skin or clothing is wet. Do not allow water to collect around the base of the unit.

ALWAYS connect the unit to a good earthen ground before use. Follow any local, state or United States National Electric Code (NEC) guidelines.

TOWING SAFETY

Towing a trailer requires care! Both the trailer and vehicle must be in good condition and securely fastened to each other to reduce the possibility of an accident. Also, some states require that large trailers be registered and licensed. Contact your local Department of Transportation office to check on license requirements for your particular unit.

Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's Gross Vehicle Weight Rating (GVWR).

Check tires on trailer for tread wear, inflation, and condition.

NEVER tow trailer using defective parts! Inspect the hitch and coupling for wear or damage.

Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened to the vehicle.

Connect safety chains in a crossing pattern under the tongue and ATTACH THE BREAKAWAY CABLE TO THE REAR BUMPER OF THE TOWING VEHICLE. Do not attach the cable to the trailer hitch.

Make sure directional and brake lights on the trailer are connected and working properly.

Check that lug nuts holding wheels are tight and that none are missing.

Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road towing speed is not to exceed 10 mph (16 km/h) or less, depending on terrain.

Before towing the trailer, check that the weight of the trailer is equal across all tires. On trailers with adjustable height hitches, adjust the angle of the trailer tongue to keep the trailer as level as possible. On units equipped with a tandem axle trailer, a large angle between the trailer and tow vehicle will cause more weight to be carried by one axle, which could cause premature wear on the tires and axles and cause potentially unsafe operating conditions.

The trailer is equipped with hydraulic surge brakes or electric surge brakes. Check the operation of the brakes by braking the vehicle at a slow speed before entering traffic. Both the trailer and the vehicle should brake smoothly. If the trailer seems to be pushing, check the level in the surge brake fluid reservoir.

When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden lane changes. If you have not pulled a trailer before, practice turning, stopping, and backing up in an area away from heavy traffic.

A film of grease on the coupler will extend coupler life and eliminate squeaking. Wipe the coupler clean and apply fresh grease each time the trailer is towed.

REPORTING TRAILER SAFETY DEFECTS

If you believe your trailer has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Magnum Power Products LLC.

If NHTSA receives similar complaints, it may open an investigation; and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or Magnum Power Products LLC.

To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-9153), go to http://www.safercar.gov; or write to:

Administrator NHTSA 1200 New Jersey Avenue S.E. Washington, DC 20590

MAGNUM DIGITAL CONTROLLER (MDC)

The MDC is an enhanced digital generator controller used to start, stop and monitor the operation of the generator and the engine. The controller constantly monitors vital generator and engine functions for a number of pre- programmed alarm and fault conditions. When a fault condition occurs, the engine will shut down automatically and the Liquid Crystal Display (LCD) window will display the fault that caused the shutdown; to resume operation, the fault condition must be resolved. The controller has the ability to provide the display readout in English and Spanish; other languages are available. A screen print out of the display screen is also available. This controller also records a history of the units performance which may be viewed at any time and will not be removed or lost when the controller is powered down.

The MDC panel consists of five sections: the CONTROL ON/OFF toggle switch and fine voltage adjustment screw, the OPERATION keypad, the LCD window, the DIAGNOSTICS keypad, and the STATUS Light Emitting Diodes (LEDs).

DIGITAL CONTROLLER FEATURES AND FUNCTIONS

1. The CONTROL ON/OFF Toggle Switch and Fine Voltage Adjustment Screw CONTROL ON/OFF toggle switch: This toggle switch powers-up and switches offthe control panel and

the controller. Fine Voltage Adjustment Screw: This screw may be adjusted to set the generator output voltage after the

link board or voltage selector switch has been changed from one phase to another. This adjustment MUST be accomplished within 45 seconds of start-up, during the V Detect, so that the unit does not experience a shutdown alarm for over or under voltage. Refer to Fine Voltage Adjustment on page 19 for more information.

2. The OPERATION Keypad ENGINE START button: The Power Display screen must be in the MAN mode in the upper left corner

of the LCD window display and the READY/MANUAL LED lit in the STATUS portion of the controller. Press the green ENGINE START button to start the unit.

ENGINE MONITORING

Engine information is shown on the Liquid Crystal Display (LCD) window in a toggling manner with the generator information after the first 60 seconds of operation and then every five seconds thereafter. The Engine Display screen will show oil pressure, engine coolant temperature, fuel level and battery voltage.

Oil Pressure: Displays engine oil pressure. The display registers oil pressure between 0-100 psi (10-689 kPa). Normal operating pressure is between 35-80 psi (241-552 kPa).

Engine Temp: Displays the temperature of the engines coolant. If the coolant temperature exceeds the maximum water temperature of 230F (110C) the engine will automatically shut down. Zero will be displayed until a minimum temperature of 100F (38C) is reached.

Fuel Level: Displays the level of fuel in the tank by percentage (50% = 1/2 tank, 75% = 3/4 tank, etc.). If the fuel level drops below a programmed low fuel point, usually at 15%, a low fuel warning and optional audio alarm will be activated. If the fuel level drops below the programmed low fuel limit, usually at five percent, the engine will automatically shut down.

Battery Volts: Displays the engine battery voltage. A normal reading is 13-14V on 12 volt systems and 24- 26V on 24 volt systems (with the engine running).

Additional information may be viewed while the unit is in Manual or Auto mode. By pressing the PAGE SELECT button, the operator will select one of the following screens; Running screen, Password screen, or History screen.

Pressing the ENTER button at a particular selection will allow the operator to scroll to the right in the LCD window to view the generator operating parameters at the time of the alarm or shutdown. The history of alarms or codes is saved in the digital controller. The most recent alarm or code is the first to be listed, with the time/date of the alarm or code at the bottom of the screen. The controller stores up to 117 codes. When full, the controller will automatically remove the oldest file. These codes will not be lost when the CONTROL ON/OFF toggle switch is powered off.

Note: To view the display screens longer, push the PAGE SELECT button on the DIAGNOSTICS keypad until you reach the Ready screen. Then press the or buttons to navigate to the screens you want. The screens will display for approximately 45 seconds.

WET STACKING

The generator is powered by a diesel engine. Diesel engines are susceptible to wet stacking if lightly loaded. Wet stacking occurs when an engine is run at less than 30% of its full load capacity, causing unburned fuel to accumulate in the exhaust system. Wet stacking can be detected by continuous black exhaust when the unit is under a constant load. It can also cause fouling of injectors and buildup on engine valves. Diesel engines operate properly when applied loads are between 30% and 100% capacity. Appropriate generator sizing is determined by the anticipated load. If the unit is in a wet stack condition, load the unit heavily for five hours or until the exhaust is clear.

FINE VOLTAGE ADJUSTMENT

Upon startup of the generator, the Running screen of the Magnum Digital Controller (MDC) will display V Detect and will countdown from 45 seconds to zero. This is a safety feature of the controller to protect the generator from over or under voltage upon startup.

V Detect is a 45 second time delay and countdown process before the MDC records the generator nominal output voltage. This nominal generator voltage is then compared to the current set point voltage of the voltage selector switch. If the nominal voltage recorded by the controller is greater than or lower than the current set point voltage of the voltage selector switch setting by 10% or more, the controller will shut the generator down automatically. The display will read: Wrn Gen L1

The output voltage of the generator may be adjusted after the generator is running by using the fine voltage adjustment screw. The adjusting screw is located directly below the CONTROL ON/OFF toggle switch on the control panel.

CONTROL OFF

Voltage Adjustment

Screw

Page 55

Page 57

This screw turns a rheostat that will provide an increase (+) or a decrease (-) in the generator output voltage as displayed on the generator display screen on the MDC. If the voltage is increased or decreased too fast or too slow, the unit will automatically shut down. This adjustment needs to be made within the 45 second delay and countdown to zero period.

To adjust the output voltage, check the output voltage on the Liquid Crystal Display (LCD) window labeled Gen freq & Hz. Look at the L1N voltage or the L12 voltage on the display. The generator nominal output voltage should be within 10% of the voltage rating on the voltage selector switch.

To adjust the output voltage, use a flat head screwdriver to turn the screw in the desired direction until the required voltage shown on the LCD window matches the stated voltage on the voltage selector switch.

For Example: With the voltage selector switch set to 208/120V 3 phase position, the voltage displayed on the Gen freq & Hz screen must be within 10% of the 208/120 position (188-228V Line to Line/108-132V Line to Neutral).

Note: Each time the voltage selector switch is changed from one setting to another, an adjustment will need to be made using the fine voltage adjustment screw.

PRE-START CHECKLIST

Before starting the generator, carefully read the pre-start check list. Make sure all of the items are checked before trying to start the generator. This check list applies to both manual and remote starting of the generator.

Read and understand ALL safety sections at the beginning of this manual. Make sure the CONTROL ON/OFF toggle switch is in the OFF/O position. Make sure the circuit breakers (main and convenience) are switched OFF/O. Check that the generator is properly grounded to a good earthen ground per any local and National

Electric Code (NEC) regulations. Verify all electrical connections at the connection lugs are tight and wired correctly. Check the voltage selector switch and make sure that it is set to the desired voltage. Is the voltage selector switch locked? Is the generator sitting level? Thoroughly check for any water inside the unit, on, or near the generator. Dry the unit before starting. Check oil, coolant, and fuel levels, and engine battery connections. Check the engine fan belt tension and condition. Check the engine fan belt guard. Check the engine exhaust system for loose or rusted components. Check the radiator and surrounding shroud for debris. Are any of the generator covers loose or missing? Are all preventive maintenance procedures up to date? Check that the battery disconnect switch is on, if equipped.

ENGINE BREAK-IN REQUIREMENTS

Note: During the first 20 hours of operation, avoid long periods of no load or sustained maximum load operation. If the generator is to run for longer than five minutes without a load, shut the generator down.

John Deere engines are supplied with engine break-in oil from the factory. Extra care during the first 100 hours of engine operation will result in better performance and longer engine life. DO NOT exceed 100 hours of operation with the break-in oil. Operate the engine at heavy loads (60-90% of maximum) as much as possible. If the engine has spent significant time at idle, constant speed(s), and/or light load, or if makeup oil is required, a longer break-in period may be needed. Consult the engine operators manual for a full description of necessary procedures on the addition of break-in oil and extension of the break-in period. For more information on regular maintenance intervals, refer to Basic Maintenance Schedule - John Deere Engine on page 37.

After a few minutes of operation, the engine will be warmed up and the LCD window will show engine and generator operating parameters. Temperature will be shown as 0 until the engine temperature is approximately 100F (38C).

11. Check the generator for excessive noise or vibration and any coolant, oil or fuel leaks before applying any loads.

12. Check that the AC output voltage is correct. The output voltage can be fine adjusted by using the fine voltage adjustment screw (rheostat). Refer to Fine Voltage Adjustment on page 19.

13. Check that the frequency (Hz) is correct. With no loads connected to the generator, the frequency should read approximately 60 Hz, depending on the type of engine governing used.

14. If all wiring connections have been attached and secured correctly, switch the main circuit breaker to the ON/I position and then add any loads attached to the convenience receptacles by switching the respective circuit breaker to the ON/I position. You will notice a slight change in engine sound when a load is applied to the unit.

AUTO (REMOTE) STARTING OF THE GENERATOR

The AUTO button is used when the generator is started from a location other than the control panel and by using a transfer switch. AUTO (remote start) is the normal setting when the generator is being used as a standby power supply. Before putting the generator in the AUTO mode, review the Pre-Start Check List and Manual Starting of the Generator. Refer to Pre-Start Checklist on page 20 and Manual Starting Of The Generator on page 21. Follow all safety warnings and information on isolating the generator with a transfer switch if the unit is to be used as a standby

2. Check for leaks in the fuel tank. The fuel tank should not run dry under normal circ*mstances. The engine controller will shut the engine down when there is 5% of fuel remaining in the tank. This is done to keep the fuel lines from running dry.

3. If the fuel level is good and no leaks are found, check the fuel level sender and the connecting wiring for damage. To check for continuity between the sender and the engine controller, remove the appropriate bolts from the control panel to access the inside of the control box. Consult the appropriate DC wiring diagram in the parts manual for the proper path between the engine controller and the fuel level sender.

LOW OIL PRESSURE SHUTDOWN

1. Check the level of the engine oil with the dipstick. The engine controller will shut the engine down when the oil pressure is less than 20 psi (138 kPa). Add oil if required.

2. Visually inspect the engine for oil leaks. 3. If the oil level is good, restart the unit and verify the loss of oil pressure. Shut the engine down immediately

if the oil pressure value does not read 5 psi (34 kPa) within five seconds. 4. Check the oil sender. To identify corrective action, refer to the troubleshooting section of the engine

operators manual provided with the unit.

LOW COOLANT LEVEL SHUTDOWN

1. Allow the engine to cool. 2. Check the coolant level in the radiator. To access the radiator cap, you must remove the access panel

from the top of the enclosure directly above the radiator. Add coolant until it is 3/4 in. (1.9 cm) below the filler neck. Secure the radiator cap back into its original position.

3. Inspect coolant hoses, engine block and water pump for visible leaks. 4. Check the engine oil to verify no coolant has mixed with it (oil will appear milky if coolant is present).

Consult the engine operators manual for additional information.

HIGH COOLANT TEMPERATURE SHUTDOWN

1. Check the coolant level in the overflow jug. 2. Restart the engine and read the coolant temperature to verify a high coolant temperature shutdown. Stop

the engine immediately if the coolant temperature is 230F (110C) or more. 3. Allow the engine to cool. Add coolant to the overflow jug if it is low and then check the level of coolant

in the radiator. To access the radiator cap, you must remove the access panel from the top of the enclosure directly above the radiator. Add coolant until it is 3/4 in. (1.9 cm) below the filler neck. Secure the radiator cap back into its original position.

4. Check the radiator shroud and ducting for blockage and remove any foreign matter. 5. Inspect coolant hoses, engine block and water pump for visible leaks. 6. Check the tension of the serpentine drive belt for the water pump. 7. If no other problems are found, remove the load on the generator and restart the engine. Check the

coolant temperature and shut the engine down immediately if it starts to overheat. Consult the engine operators manual for additional information on engine overheating.

OVERCRANK SHUTDOWN

1. Check the fuel level in the tank. 2. Check for proper operation of the fuel pump. 3. Check the air filter for blockage. 4. If the engine will not start, consult the engine operators manual for additional information on trouble-

shooting starting problems.

OVERSPEED OR UNDERSPEED SHUTDOWN

1. Disconnect all loads and restart the generator. Read the frequency (Hz) on the LCD display. With no loads on the generator, the frequency should read 60.0 Hz.

2. If the frequency is above or below 60.0 Hz, the engine speed will have to be adjusted. Refer to the engine operators manual for throttle adjustments on mechanical governed units and see the electronic governor manual for electronically controlled units.

The generator is equipped with connection lugs, located behind the lug box door next to the customer convenience receptacles. The lugs provide connection points for attachment of external loads to the generator. A large decal on the inside of the connection lug door details the proper connections for selected voltages.

WARNING It is HIGHLY RECOMMENDED that only a trained and licensed electrician perform any wiring and related connections to the generator. Installation should be in compliance with the National Electric Code (NEC) as well as any local or state guidelines as required by law. Failure to follow proper installation requirements may result in equipment or

property damage, personal injury or death.

WARNING Before any connections are made to the generator, make sure that the main circuit

breaker and the engine start switch are in the OFF/O position and that the negative (-) battery cable is disconnected. Potentially lethal voltages may be present at the

generator connection lugs.

DANGER IMPROPER OR INCORRECT CONNECTIONS TO A BUILDINGS ELECTRICAL SYSTEM CAN CAUSE POTENTIALLY LETHAL VOLTAGES TO BACKFEED IN UTILITY LINES. THIS MAY RESULT IN INJURY OR ELECTROCUTION TO UTILITY WORKERS NEARBY. MAKE SURE THE GENERATOR IS SUPPLING POWER TO AN ISOLATED OBJECT OR

BUILDING THAT IS NOT CONNECTED TO ANY UTILITY LINES.

Connections to the lugs should be made by running the power cables up through the slots in the plastic cable guide at the base of the lug box. DO NOT make any connections directly to the lugs. The lug box door is equipped with a safety interlock switch that will automatically trip the main circuit breaker and disable the voltage regulator when the lug door is opened. Use a hex-wrench to tighten the cable connections.

WARNING Never attempt to disable or modify the lug door safety switches. Equipment damage, personal injury or death

may result.

A ground connection is located next to the connection lugs. The unit MUST be connected to a good earthen ground for proper operating safety. The generator neutral is bonded to ground when it is shipped from the factory. The bonding plate will need to be removed when the generator is used as a standby power source. INSTALLA- TION SHOULD BE IN COMPLIANCE WITH NATIONAL ELECTRIC CODE (NEC), AS WELL AS ANY STATE AND LOCAL CODES OR REGULATIONS.

VOLTAGE SELECTOR SWITCHES

The voltage selector switches are located on a panel attached to the generator behind the door located next to the fuel tank filler. One selector switch is a three position switch that changes the connections between the generator output leads and the connection lugs on the main control panel. The other selector switch is a two position switch that changes the resistance to the voltage regulator to set the generator output voltage to 480V or 600V. Voltage ranges are selected by rotating the handles on the switches to the desired voltage.

NEVER CHANGE THE VOLTAGE SELECTOR SWITCHES WHILE THE ENGINE IS RUNNING. This will cause severe arcing and damage to the switches and generator windings.

EMERGENCY STOP SWITCH

The generator is equipped with one EMERGENCY STOP switch, located on the rear corner of the unit next to the control panel door. The switch is clearly labeled with EMERGENCY STOP and is red. The switch can be accessed and activated with all doors closed and locked.

Activate the EMERGENCY STOP switch by pushing the red button in until it locks down. This will trip the main circuit breaker which will open the contact disconnecting the load to the connection lugs. This will also open the fuel circuit, shutting down the engine. The Emer- gency Stop fault will be displayed on the LCD.

The switch will remain closed until it is pulled out.

Use the EMERGENCY STOP switch only when the generator must be shut down imme- diately. For any other shut down, refer to Shutting Down on page 23.

MAIN CIRCUIT BREAKER

The main circuit breaker is located on the main control panel. When the breaker is in the OFF/O position, power is interrupted between the customer connection lugs and the generator. Once the connections have been made to the connection lugs and the generator has been started and allowed to reach normal operating temperature, the breaker may be switched to the ON/I position.

The main circuit breaker will be tripped, disconnecting power to the connection lugs if any of the following items occur while the unit is running:

1. Overload of the generator circuits to the connection lugs (208/120V only). 2. The door covering the customer connection lugs is opened. 3. If the EMERGENCY STOP switch is activated.

Make sure any problems that cause the main circuit breaker to trip are corrected before returning the switch to the ON/I position.

WARNING The main circuit breaker interrupts power to the customer connection lugs only! The customer convenience receptacles have power even if the main circuit breaker is in the OFF/O position. To disconnect power to the convenience receptacle, use the

individual circuit breakers located near each receptacle.

GENERATOR BOX CIRCUIT BREAKERS

These circuit breakers are located on the generator box near the phase switches. The breakers protect the extra taps (T13 and T14) that go from the generator box to the control box. If one of these breakers were to open, the generator would not output 600V when 600V is selected. This is because the voltage regulator wouldnt be getting any power. However, all the other voltage settings would continue to work.

VOLTAGE REGULATION

The electronic voltage regulator controls the output of the generator by regulating the current into the exciter field. The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and voltage roll-off (U/F). The voltage regulator on the unit is adjusted before shipment from the factory. Contact Magnum Power Products LLC for additional information before attempting to adjust the voltage regulator.

Note: For units equipped with a Marathon DVR2000E+ digital voltage regulator, please refer to the Marathon operating manual provided with the unit.

CUSTOMER CONVENIENCE RECEPTACLES

The generator is equipped with five convenience receptacles. The large receptacles are 240/120VAC twist-lock receptacles rated at 50A each. The smaller receptacles are 120VAC duplex receptacles rated at 20A each with ground fault circuit interrupt (GFCI) protection. These receptacles are not routed through the main circuit breaker. Each receptacle has its own circuit breaker, located directly above or next to the receptacle. Each breaker is sized to the maximum rating of the corresponding receptacle.

Power to the recpetacles is available any time the generator is running, EVEN IF THE MAIN CIRCUIT BREAKER IS OFF/O. MAKE SURE THAT ANY EQUIPMENT CON- NECTED TO THE CONVENIENCE RECEPTACLES IS

TURNED OFF BEFORE TURNING THE BREAKERS ON. Make sure that the voltage selector switches are in the

proper position and that the output voltage is correct for the equipment that is connected to the receptacles. Improper

voltage may cause equipment damage or malfunction.

DERATING FOR ALTITUDE

All generator sets are subject to derating for altitude and temperature; this will reduce the available power for operation of tools and accessories connected to the auxiliary receptacles. Typical reductions in performance are 2-4% for every 1000 ft. (305 m) of elevation and 1% per 10F (-12C) increase in ambient air temperature over 72F (22C).

REMOTE START TERMINAL BLOCK

The remote start terminal block is located just to the right of the three twist-lock convenience receptacles. It provides a connection for installation of a remote start switch which will allow the generator to be started by a remote dry-contact closure switch.

Before pressing the "AUTO" button, verify that the contacts on any remote switch linked to the generator are OPEN. If the contacts on a remote switch are closed, the generator will crank and start when "AUTO" is selected. Attach the switch leads to the two unused terminals on the generators remote start block. For additional information on starting the generator, refer to Manual Starting Of The Generator on page 21.

TRANSFER SWITCH

The generator neutral is bonded to ground when shipped from the factory. The bonding plate will need to be removed when the generator is used as a standby power source. Installation should be in compliance with National Electric Code (NEC), as well as any state and local

codes or regualtions.

CAUTION Do not use 120V GFCI outlets when generator at 480 or 600 volts. Equipment damage or personal injury may result.

CAUTION Do not use 240V twist lock outlets when generator at 600 volts. Equipment damage or personal injury may result.

Page 102

When the generator is used as a standby power supply, it must be equipped with a transfer switch which isolates it from the utilitys distribution system. A transfer switch is designed to transfer electrical loads from the normal power source (utility) to the emergency power source (generator) when normal voltage falls below a prescribed level. The transfer switch automatically returns the load back to the normal source when power is restored back to operating levels.

DANGER FAILURE TO ISOLATE THE GENERATOR FROM THE NORMAL POWER UTILITY CAN CAUSE POTENTIALLY LETHAL VOLTAGE TO BACKFEED INTO THE UTILITY LINES. THIS MAY RESULT IN INJURY OR ELECTROCUTION OF UTILITY WORKERS NEARBY. MAKE SURE THE GENERATOR IS ISOLATED BY A TRANSFER SWITCH FROM ANY LOCAL UTILITY LINES. THIS ALSO APPLIES IF THE GENERATOR IS BEING USED AS

A BACKUP TO SOME OTHER TYPE OF POWER SUPPLY.

Installation of a transfer switch or other type of remote starting device is the responsibility of the generator user. Installation of such devices must be performed by following all directions supplied by the manufacturer of the switch. If attaching the generator to a power supply normally serviced by a utility company, notify the utility company and check local and state regulations. Familiarize yourself with all instructions and warning labels supplied with the switch.

WARNING ONLY a licensed electrician should perform wiring and related connections to the

generator. Installation should be in compliance of the National Electric Code (NEC) as well as any state or local codes or regulations. Failure to follow these procedures could result in property damage, personal injury or death. Before any connections

are attempted, make sure the main circuit breaker and the engine start switch are in the OFF/O position and that the negative (-) battery cable has been disconnected

from the engine starting battery.

When using the generator as a standby or substitute power supply, make sure the output voltage and phase rotation of the generator match those of the local power utility. Improper

voltage or phase rotation may cause equipment damage or malfunction.

AUTO EXERCISE TIMER

Note: The controller must be in AUTO mode to run at the programmed time. Use a trickle battery charger or solargizer to prevent the controller from draining the battery while in AUTO mode.

DAILY WALK AROUND INSPECTION

Failure to perform a daily inspection may result in serious damage to the prime mover.

Look for conditions that could hinder performance or safety, such as (but not limited to) oil/coolant/fuel leakage, blocked vents, loose/missing hardware, and electrical connections.

Visually inspect the fan belt for cracks, fraying, stretching, and verify the belt is properly seated in the pulley grooves. Replace the belt according to the manufacturers recommendations.

Note: At the 500 hour/12 month service interval, it is recommended the belt be removed and checked for wear. While the belt is removed, inspect pulleys and bearings. Rotate and feel for hard turning or unusual sounds. If pulleys or bearings need replacement contact the engine manufacturer.

ENGINE AND GENERATOR MAINTENANCE

Check the engine oil level daily before starting the engine. DO NOT start the generator if the oil level is below the ADD mark on the dipstick. The normal operating level for the engine oil is anywhere in the crosshatch pattern between the FULL and ADD markings. Add oil to the engine only if the level is below the ADD mark on the bottom of the crosshatch pattern. DO NOT OVERFILL the crankcase. Consult the engine operators manual for the proper grade of oil, including special operating conditions such as a change in season or climate.

Check the coolant level daily. The coolant is checked by visually inspecting the level in the coolant overflow jug, located near the radiator. The normal operating level is anywhere between the FULL and ADD markings on the overflow jug, with the optimum level noted as NORMAL RANGE. WHEN THE ENGINE IS STOPPED AND COMPLETELY COOL, coolant may be added directly to the overflow jug. Consult the engine operators manual for coolant recommendations and proper mixture.

Check the condition of the air filter by viewing the level of vacuum draw on the filter minder gauge. Replace the air filter when the yellow center bar reaches the red section on the gauge (20 in. H20).

Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely and properly over a long period of time, periodic maintenance and occasional repairs are necessary. NEVER perform even routine service (oil/filter changes, cleaning, etc.) unless all electrical components are shut off. When servicing this equipment always follow the instructions listed below.

Make sure the engine start switch is turned to the OFF/O position. Verify all circuit breakers are open (OFF/O). Activate (push in) the EMERGENCY STOP switch. Disconnect the negative (-) terminal on the battery. Attach a DO NOT START sign to the control panel. This will notify everyone the unit is being serviced and

will reduce the chance of someone inadvertently trying to start the unit. If the unit is connected to a remote start or transfer switch, make sure the remote switch is also off and

tagged. Never wash the unit with a high pressure hose or with any kind of power washer. Never wash the engine block or fuel tank with a power washer or steam cleaner. Water may enter the

cabinet and collect in the generator windings or other electrical parts causing damage.

The automatic tensioner cannot be adjusted or repaired and is designed to maintain proper tension over the belts life. Units with the automatic belt tensioner must be inspected according to the manufacturers specifications.

LIFTING THE GENERATOR

A central lift point is located on the top of the generator. The central lift point is connected to a lift structure inside the unit. Attach a sling or hook directly to the central lift point only if the devices are in good condition and the equipment being used to raise the unit has sufficient capacity. For approximate weights, refer to the Specifications section pages 9- 10. Always remain aware of others around you when moving or lifting the generator. Keep the cabinet doors closed and locked.

TOWING THE TRAILER

1. Use the jack to raise or lower the trailer onto the hitch of the towing vehicle. Lock the hitch coupling and attach the safety chains or cables to the vehicle. Release the jack locking pin and rotate the jack into the travel position. Make sure the locking pin snaps into place.

2. Connect any trailer wiring to the tow vehicle. Check for proper operation of the stop and signal lights.

3. Make sure all doors are closed and secure.

4. Check for proper inflation of the trailer tires. For maximum tire pressures, refer to the Specifications section pages 9-10.

5. Check the wheel lugs, tighten or replace any that are loose or missing. If a tire has been removed for axle service or replaced, tighten the lugs in the order shown to the following specifications: A. Start all lug nuts by hand. B. First pass tighten to 20-25 ft-lbs (27-33 Nm). C. Second pass tighten to 50-60 ft-lbs (67-81 Nm). D. Third pass tighten to 90-120 ft-lbs (122-162 Nm).

Note: After the first road use, re-torque the lug nuts in sequence.

6. Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road towing speed is not to exceed 10 mph (16 km/h) or less, depending on terrain.

TRAILER WHEEL BEARINGS

Some trailers are equipped with a grease zerk fitting to allow lubrication of the wheel bearings without the need to disassemble the axle hub. To lubricate the axle bearings, remove the small rubber plug on the grease cap, attach a standard grease gun fitting to the grease zerk fitting and pump grease into the fitting until new grease is visible around the nozzle of the grease gun. Use only a high quality grease made specifically for lubrication of wheel bearings. Wipe any excess grease from the hub with a clean cloth and replace the rubber plug when finished. The minimum recommended lubrication is every 12 months or 12,000 miles (19,312 km). More frequent lubrication may be required under extremely dusty or damp operating conditions.

JACK MAINTENANCE

The following procedures should be performed at least annually.

SIDE-WIND MODELS

The internal gearing and bushings of the jack must be kept lubricated. Apply a small amount of automotive grease to the internal gearing by removing the jack cover, or if equipped, use a needle nose applicator or standard grease gun on the lubrication point found on the side of the jack near the crank. Rotate the jack handle to distribute the grease evenly.

A lightweight oil must be applied to the handle unit at both sides of the tube. If equipped, the axle bolt and nut assembly of the caster wheel must also be lubricated with the same light

weight oil.

TOP-WIND MODELS

Apply a lightweight oil to the screw stem.

CHECKING GENERATOR DRIVE PLATE TORQUE

Follow the procedure below to check the torque of the generator drive plate bolts in accordance with the maintenance chart. Refer to Basic Maintenance Schedule - John Deere Engine on page 37.

1. Disconnect the engine starting battery.

2. Remove the generator fan guard.

3. Torque each of the drive plate bolts to the appropriate specification in the table below.

4. Reinstall the generator fan guard. Reconnect the battery.

VISCOUS FAN CLUTCH

The viscous fan clutch option allows the engine cooling fan to engage at lower speeds and disengage at higher speeds, increasing cooling system efficiency. The cooling fan will engage at full speed when the coolant temperature rises. When the fan is operating at full speed, it will switch to a slower speed when the coolant temperature drops. There will be an audible difference when the engine cooling fan switches speeds. Depending on unit model, the temperature ranges vary between 170F and 200F (77F and 93C).

AUXILIARY FUEL TANK OPTION

The auxiliary fuel tank option is designed so the unit can run from an external fuel tank. The unit is still programmed to shut down when the internal tanks fuel level drops below 5%. In order for the unit to run off of an auxiliary tank, the fuel level in the internal tank must remain over 5%. To operate the unit using an auxiliary fuel tank, use the following procedure:

1. Shut down the unit and check that the level of fuel in the tank is above 5%.

2. Attach the auxiliary fuel tank's fuel lines to the AUXILIARY FUEL INLET and AUXILIARY FUEL OUTLET fittings on the unit.

3. Open the AUXILIARY FUEL INLET and AUXILIARY FUEL OUTLET valves located inside of the right front door.

FUEL TRANSFER PUMP OPTION

The fuel transfer pump option allows the fuel tank to be refilled from an external bulk fuel source. When the fuel transfer switch is on, anytime the fuel level drops below 15% the fuel transfer pump will begin pumping fuel from an external bulk fuel source into the fuel tank on the unit. The fuel transfer pump will shut off when the fuel level of the internal tank reaches 90%. The pump will also be monitored to ensure a certain percentage increase in fuel level over a given period of time to prevent the pump from running dry. To operate the fuel transfer system, use the following procedure:

1. Shut down the unit.

Note: If the external bulk fuel supply is already connected, the unit does not have to be shut down to turn the fuel transfer pump option on or off.

2. Attach the external bulk fuel supply to the FUEL TRANSFER INLET fitting on the unit.

3. Turn on the fuel transfer switch.
