MAINTENANCE
CAUTION
A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next
use. Never tension a warm chain before storing as chains shrink when cool. This can damage the
chain, bar and saw.
CHAIN MAINTENANCE
(see figure 35)
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:
•
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 or
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. Have the drive sprocket
replaced by an authorized service center if there are any signs of wear or damage.
•
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.
