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.
