A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.
1. Clean the cover and the area around it to
keep dirt and sawdust from falling into
the carburetor chamber when the cover
is removed.

BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be neces-
sary to service your bar. A worn bar will dam-
age your chain and make cutting difficult.
After each use, ensure ON/STOP switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
S Move ON/STOP switch to the STOP posi-
tion.
S Loosen and remove chain brake nuts and
chain brake. Remove bar and chain from
saw.
S Clean the oil holes and bar groove after each
5 hours of operation.
Remove Sawdust From
Guide Bar Groove
S Burring of guide bar rails is a normal
process of rail wear. Remove these burrs
with a flat file.
S When rail top is uneven, use a flat file to re-
store square edges and sides.
Worn Groove
Replace guide bar when the groove is worn,
the guide bar is bent or cracked, or when
excess heating or burring of the rails occurs.
If replacement is necessary, use only the guide
bar specified for your saw in the repair parts list
or on the decal located on the chain saw.
