Maintenance

MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES

Before working on the generator, ensure the fol- lowing:

•The AUTO/OFF/MANUAL switch is in the OFF position.

•The 15A fuse has been removed from the con- trol box.

•The 120VAC supply to the battery charger is switched OFF.

‹EVERY THREE MONTHS

1.Check battery condition.

2.Inspect and test fuel system.

3.Check transfer switch.

4.Inspect exhaust system.

5.Check engine ignition system.

6.Check fan belts.

‹ONCE EVERY SIX MONTHS

1.Test Engine Safety Devices (low oil pressure, low coolant level, high coolant temperature).

‹ONCE ANNUALLY

1.Test engine governor; adjust or repair, if needed.

2.Clean, inspect generator.

3.Flush cooling system.

COOLING SYSTEM

Air intake and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. This includes such obstruc- tions as high grass, weeds, brush, leaves and snow.

Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down. (See the installation diagram.)

The exhaust system parts from this product get extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.

OVERLOAD PROTECTION FOR ENGINE DC ELECTRICAL SYSTEM

Engine cranking, start up and running are controlled by a solid state Engine Controller circuit board. Battery voltage is delivered to that circuit board via a 15 amp fuse. These overcurrent protection devices will open if the circuit is overloaded.

If a circuit breaker opens or a fuse element melts, find the cause of the overload before resetting the circuit breaker or replacing the fuse.

‹FIRST 30 OPERATING HOURS

1. Change engine "break-in" oil and filter.

‹FIRST 100 OPERATING HOURS

1.Change engine oil and oil filter. After initial change, service engine oil and filter at 100 operat- ing hours or six months, whichever comes first.

2.Retorque cylinder head.

3.Retorque intake and exhaust manifold.

‹EVERY 500 OPERATING HOURS

1.Service air cleaner.

2.Check starter.

3.Check engine DC alternator.

CHECKING FLUID LEVELS

‹CHECK ENGINE OIL

Check engine crankcase oil level (Figure 10.1) at least every 20 hours of operation, or prior to use.

•Remove oil dipstick and wipe dry with a clean, lint- free cloth.

•Install oil dipstick, then remove again.

•Oil should be between FULL and ADD marks.

•If oil level is below the dipstick ADD mark, remove oil fill cap-. Add the recommended oil to bring oil level up to the FULL mark. DO NOT FILL ABOVE THE “FULL” MARK. See “Engine Oil Recommen- dations” for recommended oils.

‹EVERY 800 OPERATING HOURS

1.Retorque cylinder head.

2.Retorque intake and exhaust manifold.

3.Check engine compression.

4.Check valve clearance.
