MAINTENANCE PERFORMED BY
SERVICE DEALERS/CONTRACTORS

Before working on the Stationary Emergency
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.
• The negative battery cable has been removed.

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.
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 100 operating hours or six months,
whichever comes first.
2. Retorque intake and exhaust manifold.

EVERY 500 OPERATING HOURS

1. Service air filter.
2. Check starter.
3. Check engine DC alternator.

Maintenance

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.
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.
