Chain
Braking
System
Your chain saw is equipped with a motor chain braking system which
wilt stop the chain quickly each time you release the trigger. This
system should be tested before every use.
Saw Chain
Sharpness
The cutters wilt dull immediately if they touch the ground or a nail
while cutting. Refer to "Sharpening the Chain".
Saw Chain Tension
This should be done regularly. Refer to "Adjusting Chain Tension".
Common
Cutting
Techniques
Felling
Felling is the process of cutting down a tree. Be sure battery is
fully charged before felling a tree so you can finish on a single
charge. Do not fell trees in high wind conditions.
Bucking
is the process of cutting a felled tree or log into lengths.
When bucking and felling operations are being performed by two
or more persons, at the same time, the felling operation should
be separated from the bucking operation by a distance of at least
twice the height of the tree being felled. Trees should not be felled
in a manner that would endanger any person, strike any utility line
or cause any property damage. If the tree does make contact with
any utility line, the utility company should be notified immediately.
Scrutinize the surrounding overhead for dead or broken limbs or
branches which may fall during the felling process.
The chain saw operator should keep on the uphill side of the
terrain as the tree is likely to roll or slide downhill after it is felled.
• (Figure O) A retreat path
should be planned and
cleared as necessary before
cuts are started. The retreat
path should extend back and
diagonally to the rear of the
expected line of fall.
• Before felling is started,
consider the natural lean
of the tree, the location of
larger branches and the wind
direction to judge which

way the tree will fall. Have wedges (wood, plastic or aluminum)
and a heavy mallet handy.
Remove dirt, stones, loose bark, nails, staples, and wire from the
tree where the felling cuts are to be made.
(Figure P) Notching
Undercut - Make the
notch 1/3 of the diameter
of the tree, perpendicular
to the direction of the fall.
Make the lower horizonta
notching cut first. This will
help to avoid pinching of
either the saw chain or
the guide bar when the
second notch is being
made.
