NOTICE
If the tree has large prop/buttress roots, these should be removed before the wedge
is cut. If the saw is used for removing the prop/buttress roots, the saw-chain should
not touch the ground so the chain does not become blunt.
Undercut and felling the tree (Fig. 17 / 18)
•
For the undercut, first cut the upper part (Pos. 1) of the wedge (Pos. 2). Cut 1/3 of
the way into the tree. Then saw the lower part (Pos. 3) of the wedge (Pos. 2). Now
remove the wedge you have cut out.
•
Afterwards, you can carry out the dropping cut on the opposite side of the tree
(Pos. 4). For this, start about 5cm above the middle of the cut. In this way, there is
enough wood between the dropping cut (Pos. 4) and the wedge (Pos. 2) so that it
functions as a hinge. This hinge is designed to guide the tree in the right direc-
tion when falling.

NOTICE
Before completing the dropping cut, if required, increase the cut using wedges to
control the direction of the fall. Exclusively use wood or plastic wedges. Steel or iron
wedges can cause kickback and damage to the device.
•
Be aware of signs that the tree is beginning to fall: Cracking sounds, the drop-
ping cut opening or movement in the upper branches.
•
When the tree begins to fall, stop the saw, put it down and leave immediately via
your escape route.
•
To prevent injuries, do not cut partly felled trees with your saw. Beware especially
of partly felled trees which are not supported. If a tree does not fall down com-
pletely, remove the saw and help the process along with a cable winch, a pulley
or a towing vehicle.
Sawing a felled tree (log division)
The term “log division“ describes the cutting up of a felled tree into logs of the de-
sired length.
