CHANGING ENGINE OIL
Refer to maintenance performed by authorized service facilities for
engine oil and filter change frequencies.
Drain the oil while the engine is still warm from running. This
means warm up the engine, shut it down and drain immediately
as follows:
1. Remove OIL DRAIN HOSE from its retaining clip.
2. Loosen and remove OIL DRAIN HOSE CAP. Drain oil com-
pletely into suitable container.
3. When all oil has drained, install and tighten OIL DRAIN HOSE
CAP, and re-install into its retaining clip.
4. Turn OIL FILTER (Figure 10.1) counterclockwise and remove.
Properly dispose of old filter.
5. Apply light coating of new engine oil to seal of new oil
filter.-Install FILTER and tighten by hand only. DO NOT OVER
TIGHTEN.
6. Remove OIL FILL CAP. Add recommended oil (see
SPECIFICATIONS). DO NOT FILL ABOVE THE DIPSTICK
“FULL” MARK. Crankcase oil capacity is 4.0 U.S. quarts (3.8
liters).
n
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.
CHANGING THE ENGINE AIR CLEANER
To replace the engine air cleaner, simply remove the air cleaner
cover and replace the air filter making sure it is positioned properly
before reattaching the cover (Figure 10.1).
See the “Service Schedule,” for air cleaner maintenance.
SPARK PLUGS
Reset the spark plug gap or replace the spark plugs as necessary
(Figure 10.2).
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” for recommended inspection.
3. Check the spark plug gap using a wire feeler gauge. Adjust the
gap to 1.07-1.17 mm (0.042-0.046 inch) by carefully bend-
ing the ground electrode (Figure 10.2).

COOLANT CHANGE
Every year, have an Authorized Service Facility drain, flush and
refill the cooling system. See “Specifications” for cooling system
recommendations.
MISCELLANEOUS MAINTENANCE
CLEANING THE 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.
BATTERY
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 precau-
tions 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 gen-•
erator. 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 battery fluid is spilled, flush the affected area with clear
water immediately.
Always wear safety glasses, rubber apron and gloves when •
handling a battery.
