INSPECT EXHAUST SYSTEM
Inspect the exhaust system at least once every three
months. Check all exhaust system pipes, mufflers,
clamps, etc. for condition, tightness, leaks, security,
damage.
CHECK FAN BELT
• Inspect fan belts every three months. Replace any
damaged, deteriorated, worn or otherwise defec-
tive belt.
• Check fan belt tension. Thumb pressure, exerted
midway between pulleys, should deflect about 3/8
to 5/8 inch. Adjust belt tension as required.
INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
DANGER
Do not attempt to adjust the governor. Only
qualified service dealers should adjust the gov-
ernor. Excessively high operating speeds are
dangerous and increase the risk of personal
injury. Low speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and voltage are supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by incor-
rect frequency and/or voltage. Only qualified
service technicians should adjust the governed
speed.
CHANGING ENGINE OIL
Refer to "Maintenance Performed by Service Dealer"
for engine oil and filter change frequencies.
Drain the oil while the engine is still warm from run-
ning. 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 completely 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 10.3) counterclockwise
and remove. 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.

“Specifications”). Crankcase oil capacity is listed
in the “Specifications”.

down into the oil pan. Recheck oil level on dip-
stick. (DO NOT FILL ABOVE THE DIPSTICK
“FULL” MARK.)
