Allow the chain to cut for you. Exert only light
pressure. Do not put pressure on chainsaw at end
of cut.
WARNING: When not in use always have the chain
brake (if equipped) engaged, unit turned off and
disconnected from the power source.
ON/OFF Switch (Fig. J)
Always be sure of your footing and grip the chainsaw firmly
with both hands with the thumb and fingers encircling
both handles.
1. To turn the unit on, push down on the the lock off lever
shown in Fig. J, and squeeze the trigger switch
the unit is running, you may release the lock off lever.
2. In order to keep the unit running you must continue
to squeeze the trigger. To turn the unit off, release
the trigger.
nOTE: If too much force is applied while making a cut the
saw will turn off. To restart saw, you must release the lock off
lever
2
and the trigger switch
Begin your cut again this time with less force. Allow the saw
to cut at its own pace.
WARNING: Never attempt to lock a switch in the
ON position.
nOTE: Use of a ground-fault circuit interrupter
(GFCI) is recommended.
Common Cutting Techniques
Felling
The process of cutting down a tree. Do not fell trees in high
wind conditions.
WARNING: Felling can result in injury. It should only be
performed by a trained person.
•
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 as shown below.

RETREAT

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.
notching Undercut - Make the notch 1/3 of the

diameter of the tree, perpendicular to the direction of
the fall. Make the lower horizontal notching cut first. This

will help to avoid pinching of either the saw chain or the
guide bar when the second notch cut is being made as
shown below.
Felling Back Cut - Make the felling back cut at least 2"
•
(51 mm) higher than the horizontal notching cut. Keep
the felling back cut parallel to the horizontal notching
cut. Make the felling back cut so enough wood is left
to act as a hinge. The hinge wood keeps the tree from
twisting and falling in the wrong direction. Do not cut
through the hinge as shown below.
•
As the felling cut gets close to the hinge the tree should

begin to fall. If there is any chance that the tree may
not fall in the desired direction or it may rock back and
bind the saw chain, stop cutting before the felling cut
is complete and use wedges to open the cut and drop
the tree along the desired line of fall. When the tree
begins to fall remove the chainsaw from the cut, stop the
motor, put the chainsaw down, then use the retreat path
planned. Be alert for overhead limbs falling and watch
your footing.

Limbing
Removing the branches from a fallen tree. When limbing,
leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut. Branches under tension
should be cut from the bottom of the branch towards the
top to avoid binding the chainsaw as shown below. Trim
limbs from opposite side keeping tree stem between you
and saw. Never make cuts with saw between your legs or
straddle the limb to be cut.
