MAINTENANCE
Retension the chain whenever the flats on the drive links
hang out of the bar groove.
NOTE: During normal saw operation, the temperature
of the chain increases. The drive links of a correctly ten-
sioned warm chain will hang approximately .050 in. out
of the bar groove. The tip of the combination wrench can
be used as a guide to help determine the correct warm
chain tension.
NOTE: New chains tend to stretch; check the chain ten-
sion frequently and tension as required.
CAUTION:
A chain tensioned while warm may be too tight upon
cooling. Check the “cold tension” before next use.
CHAIN MAINTENANCE
See Figures 47 - 48.
CAUTION:
Check that the switch is in the STOP “ O ” position 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.
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:
Improper filing angle of the side plate can increase the
risk of severe kickback.
Raker (depth gauge) clearance.
• Too low increases the potential for kickback.
• Not low enough decreases cutting ability.
If 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 indicated, 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 sharpened by an authorized service center
or replace with a recommended low-kickback chain.
