nRemove all dirt and debris from the engine, check the cooling fins and air cleaner for clogging, and clean as neces- sary. See Figure 16.

Keep cooling fins clean

nCarefully remove any accumulations of dirt or debris from the muffler and fuel tank. Check cooling air intake area at base of crankcase. Remove all debris. Dirt build-up in these areas can lead to engine overheating, fire, or premature wear.

This machine must never be operated with a faulty or missing spark arrestor or muf- fler. Make sure the muffler is well secured and in good condition. A worn or damaged muffler is a fire hazard and may also cause hearing loss.

nClean any debris or dirt from the hedge trimmer cutter blades. Lubricate the blades before use and after refueling. Check the cutters for damage or incor- rect adjustment.

nCheck for loose or missing screws or components. Make sure the cutter at- tachment is securely fastened.

nCheck the entire machine for leaking fuel or grease.

nMake sure nuts, bolts, and screws (ex- cept carburetor adjusting screws) are tight.
