1. Make sure nobody will be endangered by the falling
tree. Calls can be overhead due to engine noise.
Only persons occupied with felling may be present
in the felling area.
2. Set the felling notch at right angles to the direction
of fall.
a As close as possible to the ground, make a hori-
zontal cut (sole cut) over approx. 1/3 of the trunk
diameter.
Illustration T
b Make an oblique cut (roof cut) at an angle of ap-
prox. 45-60 °.
3. Set the felling cut.
a Make the felling cut parallel to the sole cut and at
least 50 mm higher.
b Only make the felling cut so far that a break-off
strip at least 50 mm wide remains.
The break-off strip prevents the tree from twisting
and falling in the wrong direction.
As the fell line approaches the break-off strip, the
tree should begin to fall.
4. Stop the felling cut if there is a danger that the tree
will not fall in the desired direction or sway back and
jam the saw chain. Use wedges to extend the cut
and fell the tree in the desired direction.
5. pull the chainsaw out of the cut when the tree starts
to fall.
6. Switch off the device.
7. Lock the chain brake.
8. Lower the chainsaw.
9. Follow the planned retreat route.
Cutting tensioned wood
DANGER
Uncontrolled movements of chainsaw and sawing
material
Life-threatening incision injuries, injuries caused by
sawed material
Plan the cut before cutting and identify any potential
dangers.
Always hold the chainsaw firmly with both hands
Tensioned wood is created when a trunk, branch, rooted
stump or sapling is tensioned by other wood.
1. Watch out for tensioned wood, as there is a danger
that it will snap back to its original position.
Illustration U
2. Carefully saw the tensioned wood from the pressure
side (see also Chapter Trimming a tensioned trunk).
Illustration V
Pruning
DANGER
Kickback
Life-threatening incision injuries
When pruning, make sure that the guide rail/chain does
not become jammed.
WARNING
Changing weight distribution when pruning
Risk of injury due to uncontrolled movement of the trunk
Select the work area so that no danger arises.
 Prune in the direction of growth.
Illustration W
 Prune from top to bottom.
 Leave larger branches below as supports to keep
the tree above the ground.
 Support the chainsaw as much as possible.
 Do not prune while standing on the trunk.
 Do not saw with the tip of the guide rail.
 Watch out for branches that are under tension. Cut
branches that are under tension from bottom to top.
 Never saw several branches at once.
 Regularly clear the work area from pruned branch-
es.
Cutting a trunk to length
DANGER
Uncontrolled movements of the chainsaw
Danger of death from incision injuries
Plan the cut before cutting and identify any potential
dangers.
Always hold the chain saw firmly with both hands.
ATTENTION
Damage to the chain due to ground contact
Make sure that the chain does not touch the ground.
1. Set the chainsaw onto the trunk with the bucking
spikes.
2. Evenly saw through the trunk.
Trimming a tensioned trunk
DANGER
Uncontrolled movement of the chainsaw
Life-threatening incision injuries
When trimming tensioned trunks, be sure to follow the
sequence of a relief cut at the pressure side and then a
separating cut at the tension side.
 Trunk is supported on 2 sides:
a For the relief cut on the pressure side, saw in
about 1/3 of the trunk diameter from above.
Illustration X
b Set the cut on the tension side from the bottom.
 Trunk is supported on 1 side:
a For the relief cut on the pressure side, saw in
about 1/3 of the trunk diameter from below.
Illustration Y
b Set the cut on the tension side from the top.
