AUTHORIZED SERVICE FACILITIES

Before working on the generator, ensure the
following:
The AUTO/OFF/MANUAL switch is in the OFF position.•
The 15A fuse has been removed from the control 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.
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 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.
EVERY 800 OPERATING HOURS
1. Retorque cylinder head.
2. Retorque intake and exhaust manifold.
3. Check engine compression.
4. Check valve clearance.
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. (See the
installation diagram.)

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.
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.
n
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.
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.
