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 bemade.
• 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 shownbelow.
• Felling Back Cut - Make the felling back cut at least 51mm
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
shownbelow.
• 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 yourfooting.

FELLING BACK CUT
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
Common Cutting Techniques
Felling
The process of cutting down a tree. Do not fell trees in high
windconditions.
WARNING: Felling can result in injury. It should only be
performed by a trainedperson.
• 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
shownbelow.
4. The tool is now ready touse.
NOTE: In the event of kickback, your left hand will come in
contact with the front guard, pushing it forward, toward the
workpiece. This will stop thetool.
Testing the Chain Brake (Fig.A, K)
Test the chain brake before every use to make sure it
operatescorrectly.
1. Place the tool on a flat, firm surface. Make sure the saw
chain
5
is clear of theground.
2. Grip the tool firmly with both hands and turn the chain
sawon.
3. Rotate your left hand forward around the front handle
13
so the back of your hand comes in contact with the chain
brake/front hand guard
3
and push it forward, toward the
workpiece. The saw chain should stopimmediately.
NOTE: If saw does not stop immediately, stop use of tool and
bring it to an authorized service center nearestyou.
WARNING: Make sure to set chain brake
beforecutting.
ON/OFF Switch (Fig.J)
Always be sure of your footing and grip the chain saw firmly
with both hands with the thumb and fingers encircling
bothhandles.
1. To turn the unit on, push down on the the lock off lever
2
,
shown in Fig.J, and squeeze the trigger switch
1
. Once the
unit is running, you may release the lock offlever.
2. In order to keep the unit running you must continue to
squeeze the trigger. To turn the unit off, release thetrigger.
NOTE: If too much force is applied while making a cut the
saw will turn off. To restart saw, you must release the trigger
switch
1
before the saw will restart. Begin your cut again this
time with less force. Allow the saw to cut at its ownpace.
WARNING: Never attempt to lock a switch in the
ONposition.
