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. 21);
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.
22.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. 23.A);
– then perform the final cut, overbucking to
reach the first cut (Fig. 23.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. 24.A);
– then perform the final cut, underbucking the
lower 2/3 to reach the first cut (Fig. 24.B).
• Sloping trunk
Always stand uphill when bucking
a sloping trunk (Fig. 25).
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.
