teeth jammed, overload cutting) during the cutting
operation, the overload circuit breaker will cut the
mains power supply automatically to protect your
chain saw.
The circuit breaker will be ac-
tivated when the cutting current is over 35-35A, and
it can be reset manually by pressing the reset but-
ton (
1.15) 30 seconds after it has cooled com-
pletely.

Checking the oil delivery
Never use the machine with-
out lubrication! You can check the oil level in the
tank through the transparent gauge. Make sure
you fill up the oil tank every time you use the ma-
chine.
Make sure the bar and the
chain are in place when you check the oil de-
livery.
Start the engine and check if the chain oil is deli-
vered as shown in the figure (Fig. 13).
2. DIRECTIONS FOR USE AND CUTTING
TECHNIQUES
Before felling or delimbing for the first time, practise
sawing logs on the ground or on trestles, so that
you can get familiar with the machine and the most
suitable sawing techniques.
Always hold the machine
with both hands when sawing.
Stop the engine immedia-
tely if the chain stops during sawing. Beware
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 same
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 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 com-
pany should be notified immediately.
– 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.
– An escape path should be planned and cleared
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 illustrated
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 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.
