CHANGING THE SPARK PLUG

An annual spark plug change is an inexpensive preven- tive measure that can help keep your unit running prop- erly throughout the year.

Only replace the spark plug with the same model plug or equivalent. See the engine manual or authorized dealer for more information.

1.Disconnect and secure the spark plug wire from the spark plug.

2.Clean the area around the spark plug to remove debris that could fall into the engine when the plug is removed.

3.Using a spark plug socket and appropriate wrench, unscrew the spark plug from the engine.

4.After first setting the proper gap on the replacement spark plug (see Engine Operator’s Manual for proper gap setting for your engine), screw the new plug in and tighten. Don’t over tighten, as this could dam- age the cylinder head.

CLEAN ENGINE FINS & AIR INTAKE AREA

The engine that powers this chipper/shredder is air- cooled and requires unobstructed air flow into and around the engine. For proper engine cooling, the cool- ing fins on the engine cylinder and cylinder head area must be kept clear of debris deposits and any other build-up that could prevent heat from radiating away from the engine.

To clean the air intake area, remove any debris build-up, and then blow out the area using a stream of com- pressed air. If a compressor is not available, use a stiff

bristle parts brush, which is available at most auto parts supply stores.

To clean the cooling fins, brush the area between the fins with a stiff bristle parts brush, and blow out any remaining debris with a stream of compressed air. If the cooling fins are caked with an oily build-up of chipper/shredder debris, using a commercially available engine cleaning aerosol may help loosen and remove the deposits.
