STOPPING OPERATION
Release the switch trigger to stop the
„
chain saw.
OPERATING THE CHAIN BRAKE
See figure 22
Check the operating condition of the chain
brake prior to each use.
Engage the chain brake by rotating
„
your left hand around the front handle,
allowing the back of your hand to push
the chain brake lever/hand guard toward
the bar while the chain is rotating rapidly.
Be sure to maintain both hands on the
saw handles at all times.
Reset the chain brake back into the
„
RUN position by grasping the top of the
chain brake lever/hand guard and pulling
toward the front handle.
If the chain brake do not stop the chain
immediately, or if the chain brake will not
stay in the run position without assistance,
take the saw to an authorized service center
for repair prior to use.
USING THE CHAIN SAW
Always be sure of your footing and hold the
chain saw firmly with both hands while the
motor is running.
BASIC FELLING, LIMBING, AND CROSS-
CUTTING TECHNIQUES See figure 9
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 beingfelled.
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
English (original instructions)
WARNING
does make contact with any utility line, the
utility company 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. 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. 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, and staples from
the tree.
NOTCHING UNDERCUT (A NOTCH CUT IN
A TREE TO DIRECT THE FALL) See Figure
10
Make the notch 1/3 in diameter of the tree,
perpendicular to the direction of falls. 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 (THE FINAL CUT IN
A TREE FELLING OPERATION, MADE ON
THE OPPOSITE SIDE OF THE TREE FROM
THE NOTCHING UNDERCUT)
See Figure 10
Make the felling back cut at least 50mm
higher than the horizontal notching cut. Keep
the felling back cut parallel to the horizontal
notching cut.Make the felling back cut so
as to leave enough wood 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 begin 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 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, and then use the retreat
path as planned. Be alert of overhead limbs
falling and watch your footing.
