CHAIN SHARPENING
Chain sharpening requires special
tools. You can purchase 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
specified in the repair parts list. The
correct 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.

tance or are unsure about performing
this procedure, call our customer as-
sistance help line at 1-800-235-5878.
