‹ 4.5.8 CHECK FAN BELT

Figure 4.2 - Oil Filter

•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.

‹4.5.9 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.

‹4.5.10 CHANGING ENGINE OIL

Refer to maintenance performed by authorized ser- vice facilities for engine oil and filter change frequen- cies.

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 4.2) 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.

DO NOT OVERTIGHTEN.

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).

OIL FILTER

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.
