MAINTENANCE
CLEANING THE AIR FILTER
See Figures 61 - 63.
For access to the air filter and carburetor area, loosen
the three screws holding the cylinder cover.
Activate chain brake.
Lift the front of the cylinder cover past chain brake
lever.
Lift the back of the cylinder cover past the handle.
Before 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.
Remove the two screws securing the air filter.
Position a flat screwdriver between the tabs and twist to
release from the air filter base.
Lift the air filter off the air filter base.
Choose one of the following cleaning options:
To lightly clean, tap the filter against a smooth, flat surface
to dislodge most saw dust and dirt particles.
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.
Reinstall 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.
Clean 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.
