Trimming branches
- Make sure the tool is running at full speed before making a cut.
- Hold the tool firmly in place to avoid possible bouncing or
sideways movement of the tool.
- Guide the tool using light pressure.
- Always cut down from the top. This way you will avoid pinching
the saw chain.
- Remove branches as shown in Fig L. Starting from branch tip
reduce the branch in logical steps cutting off small sections. "When
cutting a limb that is under tension be aware of spring back.
- When the tension in the wood fibres are released the spring
loaded limb may strike the operator and /or throw the tool out of
control"
- Remove the tool from the cut while it is running at full speed.

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, insure that battery is disconnected from the tool
before performing the following operations. Failure to do this
could result in serious personal injury.
To get the best possible performance from your chain saw it is
important to keep the teeth of the chain sharp. Follow these helpful
tips for proper saw chain sharpening:
1. Remove the saw chain and use a chain vise when doing any
sharpening. See "Removing the saw chain and chain bar".
2. For best results use a 4.5mm file and a file holder or filing guide
to sharpen your chain. This will ensure you always get the correct
sharpening angles.
3. Place the file holder flat on the top plate and depth gauge of the
cutter.
4. (Figure M) Keep the correct top plate filing angle line of 30° on
your file guide parallel with your chain (file at 60° from chain
viewed from above).
5. (Figure N) Sharpen cutters on one side of the chain first. File
from the inside of each cutter to the outside. Then turn your saw
chain around and repeat the processes (2,3,4) for cutters on the
other side of the chain. Use a flat file to file the tops of the
rakers (portion of chain link in front of the cutter) so that they are
about .025" below the tips of the cutters.
6. (Figure O) Keep all cutter lengths equal.
7. 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
