CHAIN SHARPENING

tools at Sears or go to a professional
chain sharpener.
CHAIN REPLACEMENT
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 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.
