CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A dull
chain makes a sawdust powder and cuts
slowly. See CHAIN SHARPENING in the
SERVICE AND ADJUSTMENTS section.
CHECK GUIDE BAR
Conditions which require guide bar main-
tenance:
S
Saw cuts to one side or at an angle.
S Saw has to be forced through the cut.
S Inadequate supply of oil to the bar and
chain.
Check the condition of the guide bar each
time the chain is sharpened. A worn guide
bar will damage the chain and make cut-
ting difficult.
After each use, with unit disconnected
from power source, clean all sawdust from
the guide bar and sprocket hole.
To maintain guide bar:
S
Disconnect the chain saw from the pow-
er source.
S
Loosen and remove bar clamp nuts.
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
Oil Holes
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
restore square edges and sides.

worn, the guide bar is bent or crack--ed, 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.
