Chain sharpening requires special
tools. You can purchase sharpening
tools at Sears or go to a professional
chain sharpener.
CHAIN REPLACEMENT
II_WARNING: 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 CHAINTENSIONsec-
tion.
Replace the old chain when it be-
comes worn or damaged. Use only
the Low-Kickback replacement chain

the chain saw.

place and sharpen individual cutters
on your chain.
