Saw Chain Sharpening


CAUTION: Sharp chain. Always wear protective
gloves when handling the chain. The chain is sharp
and can cut you when it is not running.

WARNING: Sharp moving chain. To prevent
accidental operation, ensure that battery is removed
from the tool before performing the following
operations. Failure to do this could result in serious
personal injury.
nOTE: The cutters will dull immediately if they touch the
ground or a nail while cutting.
To get the best possible performance from your chain saw
it is important to keep the teeth of the saw chain sharp.
Follow these helpful tips for proper saw chain sharpening:
1. For best results use a 4.5 mm file and a file holder or
filing guide to sharpen your saw chain. This will ensure
you always get the correct sharpening angles.
2. Place the file holder flat on the top plate and depth
gauge of the cutter.
3. Figure T- Keep the correct top plate
of 30° on your file guide parallel with your chain (file at
60° from chain viewed from the side).
4. Sharpen cutters on one side of the chain first. File from
the inside of each cutter to the outside. Then turn your
saw around and repeat the processes (2, 3, 4) for cutters
on the other side of the chain.
nOTE: Use a flat file to file the tops of the rakers (portion
of chain link in front of the cutter) so they are about
.025" (.635 mm) below the tips of the cutters as shown
in Figure U.
5. Figure V- Keep all cutter lengths equal.
6. If damage is present on the chrome surface of the
top plates or side plates, file back until such damage
is removed.

CAUTION: After filing, the cutter will be sharp, use
extra caution during this process.
nOTE: Each time the chain is sharpened, it loses some of
the low kickback qualities and extra caution should be used.
It is recommended that a saw chain be sharpened no more
than four times.

When replacing dull chains with sharp chains it is good
practice to flip the chain bar from bottom to top.
