Warning! When the felling cut (D) has been made and only the stump (F) remains, the
tree can begin to be felled. Otherwise, you must use a felling wedge or timber compass
in order to help you.
Remove the chainsaw and turn off the motor and take a few steps back diagonally along your
retreat exit keeping an eye on the tree as it falls (see fig. 15).
Trimming
Trimming means sawing off twigs on a
tree that is lying on the ground. Begin
by sawing off the twigs highest up on
the tree. Stand on one side of the tree
trunk and trim on the other side of the
trunk (and that way you’ll have the tree
trunk as protection between you and
the chainsaw). Be careful when sawing
twigs that are fastened; they must be
sawn from the right side, otherwise the
guide will get stuck.
Warning! Never stand on the tree
trunk when trimming.

Sawing
When sawing, tree trunks lying on the ground are sawn to another length. Make sure that
you are standing steady and balanced. If the ground leans, you should stand above the trunk
when sawing. Preferably, the tree trunks should be leaning up against something so that they
are not directly lying on the ground, which would increase the likelihood of sawing into the
ground and blunting the saw chain. If the tree trunk is supported at both ends you must begin
by dividing it in the middle. Begin by sawing through half the log from above. Then make a
connecting cut underneath. Otherwise, the guide may get stuck. Make sure the saw chain
does not touch the ground.
1. A tree trunk that has support under the whole length: saw from above first, then roll the
tree trunk and make a connecting cut from above (fig. 22).
2. A tree trunk that is supported at one end (e.g. if the tree trunk is lying in a
sawhorse): Saw
from underneath first (one third of the diameter to avoid splitting) and make a connecting
cut from above.
3. A tree trunk, supported at both ends: saw from above first (one third of the diameter to
avoid splitting) and make a connecting cut from underneath (fig. 21).
Attention:
the best way of sawing is with support, preferably using a sawhorse; unless it is
not possible, and the tree trunk can be held upright with something else. Make sure that the
tree trunk is lying securely so that it cannot roll or fall down.
