Cleaning Engine

Promptly wipe off any fuel or oil spilled on the machine with clean cloth.

Using a brush or cloth, remove debris from the finger guard on the engine daily to prevent overheating of the engine. Do not use water to clean engine parts. Water could contaminate the fuel system.

Keep the throttle linkage, springs and controls free of debris.

Clean muffler area and remove any debris before operating the unit.

Spark Plug

Clean area around the spark plug base.

Remove and inspect the spark plug.

Replace the spark plug if electrodes are pitted, burned, or the porcelain is cracked. See Figure 15.

Clean the spark plug and reset the gap to .030" at least once a season or every 100 hours of operation. See Figure 15. Replace if necessary. Refer to parts list section for part number.

NOTE: Do not sandblast spark plug. Spark plug should be cleaned by scraping or wire brushing and washing with a commercial solvent.

Changing Oil

To drain oil from the engine’s crankcase, proceed as follows:

Run the engine for a few minutes to allow the oil to warm up. Warm oil flows more easily and will carry away more impurities when draining oil.

Position the chipper shredder on level surface and place an appropriate receptacle with a capacity of at least one quart beneath the oil drain tube. See Figure 16.

Oil Dipstick

Oil Drain Tube

Figure 16

Remove the oil dipstick.

Use a 3/8” wrench to unthread the oil plug from the drain tube, allowing the used oil to flow out.

Replace the oil plug and add 20 oz. of new oil (Refer to Page 9 for proper oil type). Do NOT overfill.

Replace dipstick and check oil level (Refer to Page 9).
