MAINTENANCE
 Retighten the chain cover screw securely.
 Release the tip of the guide bar and verify the
chain is now correctly tensioned using the
guidelines above.
NOTE: If the chain is too tight and will not
rotate, loosen the chain cover screw slightly,
then turn the chain tensioning screw 1/4 turn
counterclockwise. Lift up the tip of the guide bar,
retighten the chain cover screw securely, then
verify the chain will now rotate without binding.
NOTE: New chains tend to stretch; check the
chain tension frequently and adjust as needed.
NOTICE:
A 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 to avoid accidental starting and pos-
sible serious personal injury.
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.
 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
