2. DIRECTIONS FOR USE AND CUTTING
TECHNIQUES
Before felling or delimbing for the first time, prac-
tise sawing logs on the ground or on trestles, so
that you can get familiar with the machine and the
most suitable sawing techniques.
WARNING!
with both hands when sawing.

of kickback, which can occur if the bar con­
tacts an obstacle.
• Felling a tree
– When bucking and felling operations are being
performed by two or more persons at the sa me
time, the felling operations 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 man ner that
would endanger any person, stri ke any utility
line or cause any property damage. If the tree
does make contact with any u ti lity line, the com-
pany should be notified im mediately.
– The chain saw operator should keep on the up-
hill side of the terrain as the tree is likely to roll
or slide downhill after it is felled.
Make sure the bar and the

– An escape path should be planned and clea-
red as necessary before cuts are started. The
e scape path should extend back and diagonally
to the rear of the expected line of fall as illus-
trated in Figure 15.
– 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, per-
pendicular to the direction of falls as illustrated in
Figure 16.
Make the lower horizontal notching cut first.
his will help to avoid pinching 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 illustrated
in Figure 16. Keep the felling back cut paral-
lel to the horizontal notching cut. Make the fell-
ing 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 sup-
port the log off the ground. Remove the small limbs
in one cut as illustrated in Figure 17. Bran ches
under tension should be cut from the bottom up to
avoid binding the chain saw.
WARNING!
bran ches are lying on the ground, the risk of
them being under tension, the direction the
