Chain must be re-tensioned whenever the flats
on the drive links hang out of the bar groove.
During normal saw operation, the temperature
of the chain will increase. The drive links of
a correctly tensioned warm chain will hang
approximately .050 in. out of the bar groove.
NOTE: New chain tends to stretch, check chain
tension frequently and tension as required.
NOTICE:
Chain tensioned while warm, may be too tight
upon cooling. Check the "cold tension" before
next use.
CHAIN MAINTENANCE
See Figures 31 - 32.
WARNING:
Remove the battery pack and make sure the chain
has stopped before you do any work on the saw.
Use only low-kickback chain on this saw. This
fast-cutting chain will provide kickback reduction
when properly maintained.
For smooth and fast cutting, chain needs to be
maintained properly. The chain requires sharpen-
ing when the wood chips are small and powdery,
the chain must be forced through the wood dur-
ing cutting, or the chain cuts to one side. During
maintenance of your chain, consider the following:
Improper filing angle of the side plate can
increase the risk of a severe kickback.
Raker (depth gauge) clearance.
Too low increases the potential for kickback.
Not low enough decreases cutting ability.
If cutter teeth have hit hard objects such as nails
and stones, or have been abraded by mud or sand
on the wood, have service dealer sharpen chain.
NOTE: Inspect the drive sprocket for wear or dam-
age when replacing the chain. If signs of wear or
damage are present in the areas indicated, have
the drive sprocket replaced by an authorized ser-
vice center.
