2. Inspect and test fuel system.
5. Check engine ignition system.
ONCE EVERY SIX MONTHS
1. Test Engine Safety Devices (low oil pressure, low
coolant level, high coolant temperature).
1. Test engine governor; adjust or repair, if needed.
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.
3. Retorque intake and exhaust manifold.
EVERY 500 OPERATING HOURS
3. Check engine DC alternator.
EVERY 800 OPERATING HOURS
2. Retorque intake and exhaust manifold.
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
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
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-
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.
