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 12.
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 13. 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
13. 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 14. 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 15, 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 16, 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 17, 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 18. When "cutting

through", to maintain complete control release 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.

The log is lying on the sawhorse as illustrated in fig. 19.
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 (16) must be used when cut-
ting. This serves as a lever and a support when sawing.

gumming with resin, remove the chain and clean it.
Place the chain for a few hours in a vessel containing
chainsaw cleaner. There-after clean the chain with
clear water. If the chain is not used again immediately,
it must be treated with service spray or a customary

oils may tend to encrust after a time, the oiling system
should be rinsed thoroughly before storing the chain
saw for a longer period. Therefore, please fill half of the
oil reservoir (about 100 ml) with chainsaw cleaner and
close it as usual. Then switch on the chainsaw - without
bar and chain being mounted - and keep it running until
the total rinsing liquid has evaporated through the oil
opening of the chain saw. Before using the chain saw
again, it is absolutely necessary to refill the oil reservoir.
