CHAIN REPLACEMENT
_tbWARNING:
Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.

during the first 15 minutes of operation.
You should recheck your chain tension
frequently and adjust the chain tension
as required. See CHAIN TENSION sec-
tion.
Replace the old chain when it be-
comes worn or damaged. Use only the
Low-Kickback
replacement chain spe-
cified in the repair parts list. The cor-
rect replacement
bar and chain is also
specified on a decal located on the
chain saw.
See your Sears Service Center to re-
place and sharpen individual cutters
on your chain.
