In order to keep the unit running you must continue to
u
squeeze both the bail handle and the ON/OFF. To turn the
unit off, release the ON/OFF switch or bail handle.
Extended reach/Pole mode
Push the lock off switch down.
u
Grip the Pole grip (17) and then squeeze the ON/OFF
switch.
Once the unit is running, you may release the lock off
u
switch. The more the ON/OFF is depressed, the higher
the speed of the base unit.
In order to keep the unit running you must continue to
u
squeeze the ON/OFF switch. To turn the unit off, release
the ON/OFF switch.
Note: If too much force is applied while making a cut the saw
will turn off. To restart saw, you must release the ON/OFF
switch before the saw will restart. Begin your cut again this
time with less force. Allow the saw to cut at its own pace.

Common cutting techniques (fig. O, P, Q, R, S, T)
Felling
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.
A retreat path should be planned and cleared as
u
necessary before cuts are started. The retreat path should
extend back and diagonally to the rear of the expected line
of fall see figure O.
Before felling is started, consider the natural lean of the
u
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
u
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 see figure P.
Felling Back Cut - Make the felling back cut at least
u
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
see figure P.
(Original instructions)
As the felling cut gets close to the hinge the tree should
u
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 chain saw from
the cut, stop the motor, put the chain saw 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 chain saw as shown in figure Q. 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.
Bucking
Warning! Recommend that first time users should practice
cutting on a saw horse.
Cutting a felled tree or log into lengths. How you should cut
depends on how the log is supported. Use a saw horse see
figure R whenever possible.
Always start a cut with the chain running at full speed.
u
Place the bottom spike of the chain saw behind the area
u
of the initial cut as shown in figure S.
Turn the chain saw on then rotate the chain and bar down
u
into the tree, using the spike as a hinge.
Once the chain saw gets to a 45 degree angle, level
u
the chain saw again and repeat steps until you cut
fully through.
When the tree is supported along its entire length, make a
u
cut from the top (overbuck), but avoid cutting the earth as
this will dull your saw quickly.
Figure T - When supported at one end.
u
First, cut 1/3 the diameter from the underside (underbuck).
Then make the finishing cut by overbucking to meet the
first cut.
Figure U - When supported at both ends.
u
First, cut 1/3 down from the top overbuck. Then make the
finished cut by underbucking the lower 2/3 to meet the
first cut.
When on a slope always stand on the uphill side of the
u
log. When "cutting through", to maintain complete control
reduce the cutting pressure near the end of the cut without
relaxing your grip on the chain saw handles. Don't let the
chain contact the ground. After completing the cut, wait
for the saw chain to stop before you move the chain saw.
Always stop the motor before moving from cut to cut.
