CAUTION: Chain tensioned while warm, may
be too tight upon cooling. Check the "cold
tension" before next use.
CHAIN MAINTENANCE
See figure 31-32.
_1_ WARNING: Remove the battery pack and
make sure the chain has stopped before
you do any work or making any adjustments
on the saw. Failure to do so may result in
accidental starting and possible serious
injury.
Use only low-kickback chain on this saw. This
fast-cutting chain will provide kickback reduc-
tion when properly maintained.
For smooth and fast cutting, chain needs to be
maintained properly. The chain requires sharp-
ening when the wood chips are small and pow-
dery, the chain must be forced through the wood
during 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
damage when replacing the chain. If signs of
wear or damage are present in the areas indi-
cated, have the drive sprocket replaced by a
Craftsman Service dealer.
HOW TO SHARPEN THE CUTTERS
See figure 33-34.
Be careful to file all cutters to the specified an-
gles and to the same length, as fast cutting can
be obtained only when all cutters are uniform.
[] Wear gloves for protection. Properly tension
the chain prior to sharpening. Refer to Chain
Tension Section earlier in this manual. Do all
of your filing at the mid-point of the bar.
[] Use a 5/32 in. diameter round file and holder.
[] Keep the file level with the top plate of the
tooth. Do not let the file dip or rock.
[] Using light but firm pressure, stroke towards
the front corner of the tooth.
[] Lift file away from the steel on each return
stroke.
