INSPECT ENGINE GOVERNOR
‹
Visually inspect electronic governor.
DANGER

Do not attempt to adjust the governor. Only
qualified service facilities should adjust the
governor. 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 facilities
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. Cut the zip-tie securing the oil drain hose.
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 secure drain hose with a
new zip-tie.
4. Turn OIL FILTER (Figure 10.3) counterclockwise
and remove. Properly dispose of old filter.

6. Remove OIL FILL CAP and add recommend-
ed oil. Crankcase oil capacity is listed in the
"Specifications" section.

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.
CHANGING THE ENGINE AIR FILTER
‹
To replace the engine air filter, remove the air filter
cover and replace the air filter making sure it is posi-
tioned properly before reattaching the cover (Figure

SPARK PLUGS
‹
Reset the spark plug gap or replace the spark plugs
as necessary (Figure 10.4).
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 1.07-1.17 mm (0.042-0.046
inch) by carefully bending the ground electrode
(Figure 10.5).
