Remove the small branches with a single cut (Fig.
25.A).
It is recommended to cut the tensioned branches
working from the bottom upwards to prevent the
chainsaw from bending (Fig. 25.B).
6.5.4 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. 1H):
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. 26);
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. 27.A).
– Cut up to half the diameter, roll the log
over and finish 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. 28.A);
– then perform the final cut, overbucking
to reach the first cut (Fig. 28.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. 29.A);
– then perform the final cut, underbucking the
lower 2/3 to reach the first cut (Fig.. 29.B).
• Sloping trunk
Always stand uphill when bucking
a sloping trunk (Fig. 30).
During the operation, to maintain control when
the cut is almost complete, reduce the bucking
pressure without removing removing your
hands from the machine hand grips. Take all
necessary precautions to prevent the machine
from coming into contact with the ground.
6.6 STOP
To stop the machine:
1. Release the throttle trigger lever (Fig. 16.A).
2. Press the safety button (Fig. 15.A) to
turn off the electrical circuit (light off) .
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.
