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. 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 10.2) counterclockwise
and remove. Properly dispose of old filter.

is 4.0 U.S. quarts (3.8 liters).

After refilling the crankcase with oil, always
check oil level on dipstick. NEVER OPERATE
ENGINE WITH OIL BELOW THE DIPSTICK “ADD”
MARK.

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 0.76 mm (0.030 inch)
by carefully bending the ground electrode (Figure
10.4).
