MAINTENANCE
Turn the chain tensioning screw clockwise to
increase tension the chain.
NOTE: A cold chain is correctly tensioned when
there is no slack on the underside of the guide
bar, the chain is snug, and it can be turned by
hand without binding.
Retension the chain whenever the flats on the
drive links hang out of the bar groove.
NOTE: During normal saw operation, the tem-
perature of the chain increases. The drive links
of a correctly tensioned warm chain will hang
approximately 0.050 in. out of the bar groove.
The tip of the supplied 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 tension frequently and tension as re-
quired.
CAUTION
A chain tensioned while warm may be too tight
upon cooling. Check the "cold tension" before
next use to avoid possible injury.
Chain Maintenance
See Figures 37 - 39.
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 in-
crease the risk of a severe kickback.
Raker (depth gauge) clearance.
Too low increases the potential for kickback.
Not low enough decreases cutting ability.
