NOTE
Only use wedges made from wood, plastic or aluminium.
DANGER!
Danger of fatal injury from a falling tree!
Having no escape route when felling a tree represents a danger of serious and even fatal
injury!
■
Do not start the felling work until you are sure there is an unobstructed escape route away
from the tree to be felled.
DANGER!
Danger of fatal injury from an uncontrollably falling tree!
Uncontrolled falling trees can lead to extremely serious and even fatal injury!
■
In order to guarantee controlled felling of a tree, leave a bridge between the undercut and
the back cut. The length of this bridge should be approx. 1/10 of the trunk diameter.
■
Do not carry out any felling work in windy conditions.
7.3 Branch lopping
Heed the following points during this work:
■
Support the chain saw against the tree trunk during the work.
■
In the preliminary phase, leave larger, downward- pointing branches that are supporting the
tree (figure 19).
■
Cut off smaller branches with one cut.
■
Pay attention to branches under tension, and saw through these from underneath upwards
in order to avoid the chain saw becoming trapped (figure 19).
■
Do not saw off free-hanging branches from underneath.
■
Only experienced or trained people should make plunge cuts, longitudinal cuts and boring
cuts (figure 18).
10.4 Cross-cutting
Heed the following points during this work:
■
When working on a slope, always stand uphill from the tree trunk, because it could roll away
(19).
■
Guide the chain saw so that there is no part of your body in the extended sweep arc of the
saw chain.
■
Position the bumper spike directly adjacent to the cut edge and allow the chain saw to pivot
about this point. Do not exert any pressure at the end of the cut.
■
Make sure that the saw chain does not touch the ground.
■
At the end of the cut, wait for the saw chain to come to a halt before you remove the chain
saw.
■
Always switch off the motor of the chain saw before you go to the next tree. The entire
length of the tree trunk is in contact with the ground:
■
Saw through the tree trunk from above, without cutting into the ground (figure 20). Tree
trunk is lying raised at one end:
