Start the machine: Press the Safety
„
lock-off button, and then press the
switch trigger.

STOPPING OPERATION

Release the switch trigger to stop the
„
top handle 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 as-
sistance, take the saw to an authorized
service center for repair prior to use.
USING THE TOP HANDLE SAW
Always be sure of your footing and hold the
top handle 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
English (original instructions)
WARNING
tree beingfelled.
Trees should not be felled in a manner that
would endanger any person, strike any util-
ity line or cause any property damage.If the
tree does make contact with any utility line,
the utility company should be notified im-
mediately. The top handle 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 hor-
izontal 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 de-
sired direction or it may rock back and bind
the saw chain, stop cutting before the fell-
ing back cut is complete and use wedges
of wood, plastic or aluminium to open the
