Changing the Engine Oil and Filter 6. Apply a thin film of clean oil to the gasket. Install a new filter by hand until the gasket just touches the mounting surface, then turn the filter an additional 1/2 to 3/4 turn. For new engines, change the oil after the first 25 operating hours. Thereafter, under normal conditions, change the oil and filter after every 100 hours of operation. However, an engine operated in dusty or dirty conditions requires more frequent oil changes.
Servicing the Air Cleaner 4. Wrap the foam pre-cleaner in a clean cloth and squeeze it dry. Do not wring the pre-cleaner. The foam pre-cleaner must be cleaned and oiled after every 100 hours of engine operation. The paper element must be checked and/or replaced after every 200 hours of engine operation. However, the air cleaner must be cleaned more frequently if operating conditions are extremely dusty or sandy. 5. Add and evenly distribute one tablespoon of engine oil to the foam pre-cleaner.
8. Move the throttle control to the FAST position. Bend the high speed stop on the governor so that the engine runs at 3450–3550 RPM. (Fig. 25) should be touching the high speed stop. Loosen the cable clamp and adjust the cable so that the lever touches the stop. 9. Repeat step 3, then tighten the cable clamp. 10. Lower the hood and secure the latches.
5. After setting the air gap at .025 in., install the spark plugs in the cylinder head. Tighten the plugs to 10–15 ft.-lb. (14–20 N⋅m). Push the wires onto the spark plugs. 3. Remove the drain plug and allow the oil to flow into a drain pan. After the oil has drained, install the oil drain plug. 4. Remove the oil filter (Fig. 29), mounted below control panel base, and discard the filter. Thoroughly clean the filter mounting surface and make sure that a new gasket is installed in the new filter. 6.
Checking the Hydraulic Lines and Hoses Check the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating.
