6. Remove OIL FILL CAP. Add recommended oil (see
SPECIFICATIONS). DO NOT FILL ABOVE THE DIPSTICK
“FULL” MARK. Crankcase oil capacity is listed in the
“Specifications”.
After refilling the crankcase with oil, always
check oil level on dipstick. NEVER OPERATE
ENGINE WITH OIL BELOW THE DIPSTICK
“ADD” MARK.
7. Start engine and check for oil leaks.
8. Shut OFF engine and wait 10 minutes for the oil to settle down
into the oil pan. Recheck oil level on dipstick. DO NOT fill
above the dipstick "FULL" mark.
9. Dispose of used oil at a proper collection center.

CHANGING THE ENGINE AIR CLEANER
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” section for air cleaner maintenance.
SPARK PLUGS
Reset the spark plug gap or replace the spark plugs as neces-
sary.
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 condition. Replace
the spark plugs if worn or if reuse is questionable. See the
“Service Schedule” section for recommended inspection.
3. Check the spark plug gap using a wire feeler gauge. Adjust
the gap to 0.94 - 1.07 mm (0.037 - 0.042 inch) by carefully
bending the ground electrode (Figure 10.4).

COOLANT CHANGE
Every year, have an Authorized Service Facility drain, flush and
refill the cooling system. See the “Specifications” section for cool-
ing system recommendations.
MISCELLANEOUS MAINTENANCE
CLEANING THE STATIONARY EMERGENCY
GENERATOR
Keep the generator as clean and as dry as possible. Dirt and
moisture that accumulates on internal generator 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 genera-
tor may require drying.
