FELLING A TREE
◾
When bucking and felling operations are being
performed by two or more persons at the same time,
the felling operation should be separated from the
bucking operation by a distance of at least twice the
height of the tree being felled. Trees should not be
felled in a manner that would endanger any person,
strike any utility line or cause any property damage.
If the tree does make contact with any utility line, the
utility company should be notified immediately.
◾
The chain saw operator should stand on the uphill
side of the terrain, as the tree is likely to roll or slide
downhill after it is felled.
◾
An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the
expected line of fall as Fig. I shown.
I-1 Felling Direction
◾
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.
◾
Remove dirt, stones, loose bark, nails, staples and wire
from the tree.
Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular
to the direction of fall, as illustrated in Fig. J. 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
is being made.
Felling back cut
◾
Make the felling back cut at least 50 mm higher than
the horizontal notching cut as Fig. J-3 shown.
J-1 Direction of fall J-3
J-2 Notch J-4
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 gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may
not fall in 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
aluminium 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 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 Fig. K shown.
Branches under tension should be cut from the bottom up to
avoid binding the chain saw.
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. Follow the simple directions for easy
cutting.
◾
When the log is supported along its entire length as
Fig. L shown, it is cut from the top (overbucking).
◾
When the log is supported on one end, as Fig. M
shown, cut 1/3 the diameter from the underside
◾
(underbucking). Then make the finished cut by
overbucking to meet the first cut.
◾
When the log is supported on both ends, as Fig. N
shown, cut 1/3 the diameter from the top (overbuck).
Then make the finished cut by underbucking the lower
2/3 to meet the first cut.
◾
When bucking on a slope always stand on the uphill
side of the log, as Fig. O shown.
◾
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
Felling back cut
from tree to tree.

MAINTENANCE
FILLING BAR AND CHAIN LUBRICANT
NOTICE:
The chain saw is not filled with oil at the time of
purchase. It is essential to fill the tank with oil before use.
The chain is automatically lubricated with chain oil during
operation.
1. Position the chain saw on its side with its oil tank cap
facing towards.
2. Clean the cap as well as the area around and then turn
it counterclockwise to remove (Fig. P).
