Begin your cut again this time with less force. Allow the saw to
cut at its own pace.

Base mode trimming / pruning
Common cutting techniques (fig. A15, A16, A17,
A18, A19, A20)
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 A15.
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 A16.
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 A16.
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 A17. 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.
(Original instructions)
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 A18 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 a19.
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 A20 - 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 a21 - 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.
Operation
Extended reach/Pole mode for trimming & pruning
Warning! Never stand directly under the limb you are cutting.
Always position yourself out of the path of falling debris.
Never stand on a ladder (fig. A22) or other unstable
u
support while using the Pole Saw. Always avoid any
position which can cause you to lose your balance and
cause severe injury.
Keep other persons at least 15m from the work area.
u
Distractions can cause you to lose control (fig. A23).
Electrocution Hazard. To prevent shock, do not operate
u
within 15m of overhead electrical lines. Always check
surrounding area for hidden electrical lines (fig. A24).
Do not extend Pole Saw switch handle above shoulder
u
height.
Operating position (fig. A25)
Always wear:
A. Head protection.
B. Eye protection.
