 Using the combination wrench provided or a flat
blade screwdriver, remove the screw 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 protec-
tion to avoid eye injury.
 Reinstall air filter and screw, making sure that
tabs on air filter are located in channels on air
filter base.
 Reinstall air filter cover. Push down on knob and
rotate clockwise to secure.
 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.
NOTICE:
Make sure the air filter is correctly placed in the
air filter base before reassembly. Never run the
engine without the air filter, as this may cause
serious damage to the chain saw.
CLEANING THE STARTER UNIT
See Figure 65.
Use a brush or compressed air to keep the cool-
ing vents of the starter assembly free and clean
of debris.
