Select the appropriate backcut
The selection of the appropriate backcut
is dependent on the same tree
characteristics that must be noted when
determining the direction of fall and the
escape paths.
There are various different features of
these characteristics. This Instruction
Manual will only describe the two most
commonly occurring variants:
Back cut with safety strip (normal tree)
(A) Thin trunks
Implement this backcut when the trunk
diameter is smaller than the cutting
length of the machine.
Give a warning cry of "timber!" before
making the backcut.
N
Plunge cut the backcut (E) – plunge
the guide bar fully in
N
Engage the bumper spike behind
the hinge and use this as the
rotation point – reposition the
machine as little as possible

hinge (1)

N

length of the machine.
