‹ 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.

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.
