Standby Generator Sets
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 exhaust system parts from this product get extremely hot and remain 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.
•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 state of charge and 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.
FIRST 100 OPERATING HOURS
1.Change engine oil and oil filter. (After initial change, service engine oil and filter at 150 operat- ing hours or 6 months, whichever comes first.)
EVERY 500 OPERATING HOURS
1.Service air cleaner.
2.Check starter.
3.Check engine DC alternator.
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.
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 Recommendations” for recommended oils.

BATTERY FLUID
Check battery electrolyte fluid at least once weekly. Fluid should cover separators in all battery cells. If fluid level is low, add distilled water to cover tops of separators. DO NOT USE TAP WATER IN BATTERY.
