Before working on the Stationary Emergency
Generator, ensure the following:
• The AUTO/OFF/MANUAL switch is in the OFF position.
• The control panel fuse has been removed from the control

• 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.
4. Clean/re-gap spark plugs or replace as necessary.
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 150 operating 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 compartment must
be open and unobstructed for continued proper operation. This
includes such obstructions as high grass, weeds, brush, leaves
and snow.
Without sufficient cooling and ventilating air flow, the engine/gen-
erator quickly overheats, which causes it to shut down.

Maintenance


The exhaust system parts from this product
get extremely hot and remains hot after shut-
down. High grass, weeds, brush, leaves, etc.
must remain clear of the exhaust. Such mate-
rials may ignite and burn from the heat of the
exhaust system.

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.
