loosen chain by turning the adjusting
screw. Retighten bar clamp nuts.
• If chain is too loose, it will sag below
the guide bar. DO NOT operate the
saw if the chain is loose.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly.
CHAIN SHARPENING
Chain sharpening requires special
tools. You can purchase sharpening
tools at Sears or go to a professional
chain sharpener.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the
cut.
• Inadequate supply of oil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult. To maintain guide bar:
• Move On/Stop switch to "Stop."
• Remove bar and chain from saw.
• Clean all sawdust and any other
debris from the guide bar groove and
sprocket hole after each use.

Groove _ Sprocket Hole
• Add lubricant to sprocket hole after
each use.
• Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
• When rail top is uneven, use a flat
file to restore square edges and
sides.

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 de-
cal located on the chain saw.
