7.  Start engine and check for oil leaks.

Oil Filter

To replace the engine air cleaner, (part number 
0A4637), remove the air cleaner cover and replace 
the air filter making sure it is positioned properly 
before reattaching the cover.

See the “Service Schedule,” for air cleaner mainte-
nance.

Reset the spark plug gap or replace the spark plugs 
as necessary.

1.  Clean the area around the base of the spark plugs 

to keep dirt and debris out of the engine. Clean 
by scraping or washing using a wire brush and 
commercial solvent. Do not blast the spark plugs 
to clean.

2.  Remove the spark plugs and check the condi-

tion. Replace the spark plugs if worn or if reuse 
is questionable. See the “Service Schedule, for 
recommended inspection.

3.  Check the spark plug gap using a wire feeler 

gauge. Adjust the gap to 1.01 mm (0.040 inch) 
by carefully bending the ground electrode (Figure 
4.3).

Every year, have an authorized service deal-
er drain, flush and refill the cooling system. See 
SPECIFICATIONS for cooling system recommenda-
tions.

Keep the generator as clean and as dry as possible. 
Dirt and moisture that accumulates on internal gen-
erator windings have an adverse effect on insulation 
resistance.

Periodically clean generator exterior surfaces. A soft 
brush may be used to loosen caked on dirt. Use a 
vacuum system or dry, low pressure air to remove 
any accumulations of dirt. The generator is housed 
inside an all-weather enclosure, clean the enclosure 
with a soft, damp cloth or sponge and water.

Once each year, have the generator cleaned and 
inspected by an Authorized Service Dealer. That 
dealer will use dry, low pressure air to clean internal 
windings. Parts inside the control console should be 
cleaned and inspected at this time as well.

Finally, have the insulation resistance of stator and 
rotor windings checked. If insulation resistances are 
excessively low, the generator may require drying.

All lead-acid storage batteries discharge when not in 
use. Refer to specific instructions and warnings that 
accompany the battery. If such information is not 
available, observe the following precautions when 
handling a battery:

•  DO NOT use jumper cables and a booster battery 

to crank or start the generator engine.

• DO NOT recharge a weak battery while it is 

installed in the generator. Remove battery from 
generator and recharge in a well-ventilated area, 
away from fuel vapors, sparks, heat or flames.

• Battery electrolyte fluid is an extremely caustic 

sulfuric solution that can cause severe burns. DO 
NOT permit fluid to contact eyes, skin, clothing, 
painted surfaces, wiring insulation, etc. If any bat-
tery fluid is spilled, flush the affected area with 
clear water immediately.

• Always wear safety glasses, rubber apron and 

gloves when handling a battery.
