m WARNING!
If the guide rail tilts, the device may be jerked towards
the user with great force. If the user does not balance
the backward force of the saw chain with their body
strength, there is a risk that only the tip of the guide
rail will remain in contact with the wood and kick-back
will occur.
Risk of death or serious injuries!
12.7
Felling a tree (Fig. 22, 23)
m Risk of injury!
Sawing and felling work as well as all related work may
only be carried out by specially trained and briefed per-
sons.
Note
Observe the country-specific regulations for felling
work and obtain information from the relevant authority.
• Make sure that no one can be harmed by the falling
branches and trees.
• Only the persons required for the felling work may
be in the work area.
• Keep the work area at the trunk clear and tidy so that
operators have a safe standing area.
• Keep escape routes clear and tidy in order to be able
to leave the work area quickly.
• Do not carry out felling work in stronger wind condi-
tions, bad weather or poor visibility.
• Keep distances to the nearest workplace of at least
2 1/2 tree lengths.
Tree felling takes place in two steps (Fig. 23):
• Saw a felling sink in the trunk of around one third of
its diameter, on the side of the felling direction (1).
• On the opposite side (2) make the felling cut, which
must be slightly higher than the felling sink (approx.
3–5 cm).
m Risk of injury!
Never saw fully through the trunk. The area (C) serves
as a "hinge" and ensures the correct felling direction.
During felling, only stand to the side of the tree you
intend to fell! There is a risk of life-threatening injuries!
Trunks lying flat on the ground (Fig. 24)
12.8
• Cut around halfway through the trunk, then turn it
over and saw through the other side.
m Product damage!
Ensure that the guide rail does not come into contact
with the ground when sawing through a tree trunk!

Fallen trunks (Fig. 25)
We recommend supporting trunks on a sawhorse
when sawing through them. If this is not possible, the
trunk should be lifted with the aid of supporting boughs
or with support blocks and supported.
• In area A first cut around one third of the trunk di-
ameter from top to bottom, and then make the sub-
sequent cut from bottom to top.
• In area B first cut around one third of the trunk di-
ameter from bottom to top, and then saw through
from the top.
m Risk of injury!
Do not saw trunks that are strained! Splitting wood or
a tilted guide rail can result in serious injuries!
12.10 Removing branches (Fig. 26 / 27)
• Always work on the side opposite the respective
branch.
• Start at the bottom of the branch and work up.
• Saw into the branch 10–15 cm from the branch base
from bottom to top, to 1/3 of the branch diameter (1).
• Saw through the branch slightly further out from
top to bottom (2).
• Perform a cut tightly against the trunk (3). Make the
cut from top to bottom.
• During delimbing always saw off the branches that
project freely in the air first. Only lop off support
limbs once the branches have been sawn along
their length.
m Risk of injury!
With branches that are supported or strained, the saw
chain can wedge in the wood!
12.11 Release a jammed chainsaw
If the chainsaw becomes jammed during cutting, the
user should:
Switch off the chainsaw and attach it securely to-
1.
wards the inside of the tree (i.e. towards the tree
trunk) or to a separate tool rope.
2.
Pull the chainsaw out of the notch while lifting the
branch as far as necessary,
If necessary, use a handsaw or second chainsaw
3.
to loosen the jammed chainsaw by cutting at least
30 cm away from the jammed chainsaw.
