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 the bar
and chain.
Check the condition of the guide bar be-
fore each use and each time the chain
is sharpened. A worn guide bar will
damage the chain and make cutting diffi-
cult.
After each use, with unit disconnected
from power source, clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
• Disconnect the chain saw from the
power source.
• Loosen and remove bar clamp nuts
and bar clamp. Remove bar and
chain from saw.
• Clean the oil holes and bar groove
after each 5 hours of operation.
Remove Sawdust From
e Bar Groove
Sprocket Hole
• 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.

worn, the guide bar is bent or cracked,
or when excess heating or burring of
the rails occurs. If replacement is nec-
essary, contact your Sears Service
Center.

• Check bar and chain oil before use
and every 15 minutes while operat-
ing the saw. See GUIDE BAR AND
CHAIN OIL under the OPERATION
section.
INSPECT AND CLEAN UNIT AND
LABELS
• After each use, inspect complete unit
for loose or damaged parts. Clean
the unit and labels using a damp
cloth with a mild detergent.
• Wipe off the unit and labels with a
clean dry cloth.
CHAIN SHARPENING
Chain sharpening requires special
tools. You can purchase sharpening
tools at Sears or go to a professional
chain sharpener.
_i WARNING: Avoid accidental
starting. Always unplug saw from pow-
er source before installing a bar and/or
chain.
CHAIN REPLACEMENT
_i WARNING: Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.
It is normal for a new chain to stretch
during the first 15 minutes of operation.
You should recheck your chain tension
frequently and adjust the chain tension
as required. See CHECK CHAIN TEN-
SION section.
Replace the old chain when it be-
comes worn or damaged. Use only
the Low Kickback replacement chain
specified in the list of available re-
placement parts. The chain must com-
ply with kickback performance require-
ments of ANSI B175.1 when tested
with this saw.
See your Sears Service Center to re-
place and sharpen individual cutters
on your chain.
