ENGINE AND GENERATOR MAINTENANCE

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.

• Before servicing the machine, make sure the engine start switch is turned to the OFF “O” position.

• The circuit breakers are open (OFF, “O”).

• The emergency stop switch is activated (pushed in).

• The negative (-) terminal on the battery is disconnected.

• Attach a “DO NOT START” sign to the control panel. This will notify everyone that the unit is being ser-

viced 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 cab-

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

• If the unit is stored outside, check for water inside the cabinet and generator before each use. If wet, dry

the unit thoroughly before starting.

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.

The engine is 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 speeds and/or light load or if makeup oil is required, a longer break in period may be

needed. Consult the engine OPERATION AND MAINTENANCE MANUAL for a full description of necessary

procedures on the addition of break-in oil and extension of the break-in period. Use the schedule table on the following

page as a guide for regular maintenance intervals.

DAILY WALK AROUND INSPECTION

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 that the belt is properly seated in pulley groves. Replace

the belt according to the manufacturer’s recommendations.

Note: At the 500 hour/12 month service interval, it is recommended that 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 John Deere.

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

BELT TENSION

John Deere engines use two types of belt tensioners: manual and automatic. Adjust the belt using the manual tensioner

according to the manufacturer’s specifications. The automatic tensioner cannot be adjusted or repaired and is designed

to maintain proper tension over the belt’s life. Units with the automatic belt tensioner must be inspected according to

the manufacturer’s specifications.
