Only a careful and correct working
method can reduce the risk of a rebound
reliably!
Basic work technique
Before each use
– Check the chain brake (1) to ensure it is
functioning correctly.
– Checking the tensioning of the saw
chain (12).
– Check the chain catcher for damage.
– Check the on/off switch (7) to ensure it is
functioning correctly.
– Check the throttle block (13) to ensure it
is functioning correctly.
– Check whether all handles are free of oil.
– Check whether all parts of the device are
present, firmly attached and undamaged.
Sawing technique
Pulling sawing
With this technique, sawing occurs with the
underside of the saw rail from above down-
wards. The saw chain thus pushes the device
forwards away from the user. This way, the
front edge of the device forms a support,
which catches the forces which arise on the
tree trunk when sawing.
With pulling sawing, the user has much more
control over the device and can avoid
rebounds better. Therefore, this is the pre-
ferred sawing technique.
Pushing sawing
With this technique, sawing occurs with the
upper edge of the saw rail from below
upwards. The saw chain thus pushes the
device backwards towards the user. If the
saw rail twists, the device can fly towards the
user with great force.
If the user does not balance out the force of
the saw chain pushing backwards with his or
her bodily force, there is a danger that only
the tip of the saw rail will make contact with
the wood and there will thus be a rebound
(
Felling a tree
Before beginning the felling work, make sure
that:
• there are no people or animals in the fell-
ing area of the tree
• there is an obstacle-free escape route for
each participant. A retreat (B) occurs
diagonally counter to the felling direction
(A).
• the area around the trunk is free of obsta-
cles (risk of stumbling!).
• the next workplace is at least two and a
half tree lengths (A) away. Before felling,
the felling direction of the tree must be
checked and it must be ensured that
there are no objects or people in a dis-
tance of 2 1/2 tree lengths.
DANGER! Risk of injury!
This sec-
tion treats the basic work technique
when handling the device. The infor-
mation provided here does not
replace the many years of training
and experience of a professional.
Avoid any work for which you are not
sufficiently qualified! Thoughtless
handling of the device can cause
severe or even fatal injuries!
DANGER! Risk of injury!
Felling
and delimbing work may only be per-
formed by trained people! There is a
risk of fatal injuries!
