CLEANING THE AIR FILTER

See Figures 61 - 63.

nFor access to the air filter and carburetor area, loosen the three screws holding the cylinder cover.

nActivate chain brake.

nLift the front of the cylinder cover past chain brake lever.

nLift the back of the cylinder cover past the handle.

nBefore removing the air filter from the carburetor, blow or brush as much loose dirt and sawdust from around the carburetor and chamber as possible.

NOTE: Make sure to pull the choke rod out to keep the carburetor from being contaminated.

n Remove the two screws securing the air filter.

nPosition a flat screwdriver between the tabs and twist to

release from the air filter base.

n Lift the air filter off the air filter base. Choose one of the following cleaning options:

n To lightly clean, tap the filter against a smooth, flat surface to dislodge most saw dust and dirt particles.

n After every 5 hours of operation, clean in warm soapy water, rinse, and let dry completely. Replace with a new filter after every 25 hours of use.

NOTE: An alternate method is to clean the filter with compressed air. Always wear eye protection to avoid eye injury.

nReinstall the air filter, making sure that the tabs on the air filter are located in channels on the air filter bottom before tightening filter retaining screws.

nClean the pre-filter every 5 hours of use or sooner, if required. Remove the cylinder cover, starter assembly, and the fan housing baffle for access to the pre-filter in the engine housing.

NOTE: If you use an air hose for drying, blow through both sides of filter.

CAUTION:

Make sure the air filter is correctly placed in the air filter cover before reassembly. Never run the engine without the air filter, serious damage could result.
