‹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 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.

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).

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.

‹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 6, 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 elec- trode (Figure 10.4).
