tree from twisting and falling in the wrong
direction. Do not cut through the hinge.
3. Reduce the thickness of this hinge without
pulling out the bar, until the tree falls.
4. If there is any risk of the tree not falling
in the desired direction, or that it might
lose its balance moving backwards and
bending the toothed chain, stop cutting
before completing the felling back cut and
use some wooden, plastic or aluminium
wedges (Fig. 16.D) to open the cut. Force
the tree to fall along the desired line by
hitting the wedges with a sledge hammer.
5. When the tree starts to fall, it is necessary to
withdraw the machine from the cut, switch
it off (par. 6.5), lie it on the ground and take
the foreseen exit route. Beware of falling
branches and pay attention where
you put your feet.
6.4.2.c Limbing tree branches
Limbing means removing the
branches from a felled tree.
Be careful of where the branches
are lying on the ground, the risk of
them being under tension, the direction
the branch may go during cutting and
the risk of the tree being unstable
after the branch has been cut.
When limbing, it is necessary to
leave the lower, larger branches to
support the trunk on the ground.
Remove the small branches with
a single cut (Fig. 17.A).
It is recommended to cut the tensioned
branches working from the bottom upwards to
prevent the chain saw from bending (Fig. 17.B).
6.4.2.d Bucking the trunk
Bucking means sawing a tree trunk into logs.
It is essential to make sure your feet are
positioned firmly on the ground, and your weight
is distributed equally on both feet. If possible,
it is recommended to raise and support the
trunk using branches, logs or blocks of wood.
It is easier to saw a log using the
spiked bumper (Fig. 1.I):
1. Plant the spiked bumper into the log and use
it as a pivot. Cut with an arched motion to
make the bar penetrate the wood (Fig. 18);
2. Repeat several times if necessary, changing
the point where you plant the spiked bumper.
• Trunk lying on the ground
When the entire trunk is lying on the
ground, it is bucked from the top
down (overbucking) (Fig. 19.A).
– Cut up to half the diameter, roll the log over
and finishing sawing on the other side.
• Trunk resting on one end only
When the trunk is resting on one end only:
– saw through 1/3 of the diameter from the
bottom up (underbucking) (Fig. 20.A);
– then perform the final cut, overbucking
to reach the first cut (Fig. 20.B).
• Trunk resting on both ends
When the trunk is resting on both ends:
– saw through 1/3 of the diameter from the
top down (overbucking) (Fig. 21.A);
– then perform the final cut, underbucking the
lower 2/3 to reach the first cut (Fig. 21.B).
• Sloping trunk
Always stand uphill when bucking
a sloping trunk (Fig. 22).
During the operation, to maintain control when
the cut is almost complete, reduce the bucking
pressure without removing removing your
hands from the machine handgrips. Take all
necessary precautions to prevent the machine
from coming into contact with the ground.
6.5 STOP
To stop the machine:
• Release the throttle control lever (Fig. 10.A).
• Press the safety button and turn off the
electrical circuit (light off) (Fig. 9.A).
After releasing the throttle
control it takes a few seconds for
the toothed chain to stop.
Always stop the machine:
– when moving between work areas.
Do not keep your finger on the safety
button when moving the machine to avoid
accidentally enabling the machine.

6.6 AFTER OPERATION

1. Remove the battery from its housing
and recharge it (par. 7.2.2).
2. Mount the bar cover.
3. Allow the motor to cool before
storing in an enclosed space.
