REPLACE FUEL FILTER

To replace the fuel filter, drain your unit by running it dry of fuel. Remove fuel cap and its connected retainer from tank. Pull filter from tank and remove from line. Replace and reassemble.

WARNING: Disconnect the spark plug before performing maintenance, service, or adjustments except for car- buretor adjustments.

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 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 Centre to re- place and sharpen individual cutters on your chain.

TO REPLACE CHAIN:

1.Move ON/STOP switch to the STOP position.

2.Remove chain brake nuts.

3.Remove chain brake.

4.Remove the old chain.

NOTE: An adjusting pin and screw is used to adjust the tension of the chain. It is very important that the pin located on the adjusting screw aligns into the lower hole in the guide bar. Turning the screw will move the adjustment pin up and down the screw.
