Operation
Felling a tree
Risk of injury!
Felling and limbing work may be performed by trained persons
only! There is a risk of life-threatening injuries!
Before starting felling work, ensure that there are no
unauthorized persons and no animals within the fall area of the
tree and there is an obstacle-free escape route for all those
involved. People should withdraw opposite the direction of the
fall; the area around the trunk should be free of obstacles (risk
of tripping!) and the next workplace is at least two and a half
tree lengths away. Before felling the tree, check the direction in
which the tree will fall and ensure that there are neither objects
nor persons or animals within a distance of 2½ tree lengths.
A tree is felled in two stages:
Notch the trunk by approx. one third of its diameter on the side of
the direction of fall
1
(see Figure 16).
On the opposite side make the felling cut
2
which must be
slightly higher than the notch (approx. 1 - 2 inches).
Cutting limbs and trunks lying flat on the ground
Cut halfway into the trunk
A
, then turn around
B
and saw
through from the opposite side
C
(see Figure 17). When sawing
through the trunk, ensure that the saw rail does not touch the
ground!
Cutting Supported Limbs and Trunks
We recommend supporting trunks, which are to be sawn
through, on sawhorses. If this is not possible, the trunk should be
raised and supported with the aid of supporting branches or via
support blocks (see Figure 18).
In area
D
rst cut approx. one third of the trunk diameter from
top to bottom, then complete the cut from bottom to top.
In area
E
rst cut approx. one third of the trunk diameter from
bottom to top, then cut through from the top.
Do not saw trunks which are under tension! Splintering wood or
a jammed saw rail may result in serious injury!
