CHAIN MAINTENANCE

See Figures 47 - 48.

CAUTION:

Check that the switch is in the STOP “ O ” posi- tion before you work on the saw.

Use only a low-kickback chain on this saw. This fast-­cutting chain provides kickback reduction when properly maintained.

≈ .050 in.

For smooth and fast cutting, maintain the chain properly.

The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood during cutting, or the chain cuts to one side. During maintenance of the chain, consider the following:

■n Improper filing angle of the side plate can increase the risk of severe kickback.

nRaker (depth gauge) clearance.

•  Too low increases the potential for kick- back.

•  Not low enough decreases cutting ability.

nIf the cutter teeth hit hard objects such as nails and stones, or are abraded by mud or sand on the wood, have an authorized service center sharpen the chain.

NOTE:  Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage are present in the areas indi- cated, have the drive sprocket replaced by an authorized service center.

NOTE:  If you do not fully understand the correct procedure for sharpening the chain after reading the instructions that follow, have the saw chain sharp- ened by an authorized service center or replace with a recommended low-kickback chain.
