Instructions on working properly with the
chain saw
(Fig. 10 - 17)
WARNING!
Only saw logs with a diameter less than the saw's cut-
ting length. Lay people and home users may not use
the plunge cut process to saw and fell trees, as this
causes a kickback on the chain saw and can therefore
result in severe injuries and even death in certain cir-
cumstances
Always hold the saw with both hands; observe the
safety instructions and figure 6.
Important instructions for cutting and lopping: When
sawing on a slope, always stand uphill from the log
as the log can roll away!
a) Felling a Tree
When bucking and felling operations are being performed
by two or more persons, at the same time, the felling op-
eration should be separated from the bucking operation
by a distance of at least twice the height of the tree being
felled. Trees should be felled in a manner that would en-
danger any person, strike any utility line, the utility com-
pany should be notified immediately.
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.
A retreat path should be planned and cleared as neces-
sary before cuts are started. The retreat path should ex-
tend back and diagonally to the rear of the expected line
of fall as illustrated in Figure 11.
Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direc-
tion to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples, and wire
from the tree where felling cuts are to be made.
b) Notching Undercut
Make the notch 1/3 the diameter of the tree, perpendic-
ular to the direction of fall as illustrated in 10. Make the
lower horiziontal 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.
c) Felling Back Cut
Make the felling back cut at least 2 inches (50 mm) higher
than the horizontal notching cut as illustrated in Figure
11. 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 the felling cut gets close to the hinge the tree should be-
gin 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 back cut is complete
and use wedges of wood, plastic or aluminum 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.

d) Limbing a Tree
Limbing is 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 as
illustrated in Figure 12. Branches under tension should
be cut from the bottom up to avoid binding the chain saw.
e) Bucking a Log
Bucking is cutting a log into lengths. It is important to
make sure your footing is firm and your weight is evenly
distributed on both feet. When possible, the log should be
raised and supported by the use of limbs, logs or chocks.
Log resting completely on its side
When the log is supported along its entire length as
illustrated in Figure 13, it is cut from the top (over-buck).
Log resting on one side
When the log is supported on one end, as illustrated in
Figure 14, cut 1/3 the diameter from the underside (un-
derbuck). Then make the finished cut by overbucking to
meet the first cut.
Log resting on both sides
When the log is supported on both ends, as illustrated in
Figure 15, cut 1/3 of that diameter from the top overbruck.
Then make the finished cut by underbucking to meet the
first cut.
When bucking on a slope always stand on the uphill side
of the log, as illustrated in Figure 16.
When "cutting through", to maintain complete control re-
lease 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 tree to tree.
f) Spiked bumper (Fig. 17)
• Dig the spiked bumper (9) into the log and use it as
• Repeat several times if necessary, changing the point
g) Cutting a log to length on a sawhorse
The log is lying on the sawhorse as illustrated in fig. 17.
1. Hold the saw to the right of your body and tightly in
2. Keep your left arm as straight as possible.
3. Distribute your body weight over both feet.
The device must be used as intended. Hold the saw with
both hands and at a sufficient distance from your body
when sawing.
The saw must run at full speed before starting the sawing
process. The spiked bumper (9) must be used when cut-
ting. This serves as a lever and a support when sawing.
