In order to reduce the risk of injury in case of
a kickback, the device is equipped with a
chain brake which is triggered automatically
on impact and which stops the saw chain
immediately.
For safety reasons, the functionality of the
chain brake must be checked each time
before the device is used (► Checking the
chain brake – p. 58).
With less strong kickbacks, it can happen that
the chain brake is not triggered automatically.
For this reason it is important that the device
be held fast with both hands.
Only a careful and correct working method
can reduce the risk of a kickback reliably!
Basic work technique
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.
Do not perform any work for which
you are not sufficiently qualified!
Thoughtless handling of the device
can cause severe or even fatal inju-
ries!
Before each use
1. Check the chain brake to ensure it is func-
tioning correctly.
2. Check the rear hand guard for damage.
3. Check the switch-on safety lock and start
button to ensure they are functioning cor-
rectly.
4. Check whether all handles are free of oil.
5. Check whether all parts of the device are
present, firmly attached and undamaged.
6. Check the chain catcher for damage.
7. Check the chain tensioning.
8. Check oil quantity in the tank and chain
lubrication.
Sawing technique
Pulling sawing
With this technique, sawing occurs with the
underside of the saw bar 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 kick-
backs better. Therefore, this is the preferred
sawing technique.
– Saw as close to the motor block as possi-
ble and allow the claw stop to grip into the
wood. This prevents the saw from kicking
back out of control.
– If the claw stop is too firmly caught, pull
the handle of the saw upwards.
The leveraging effect will push the saw bar
down making the sawing work easier.
Pushing sawing
With this technique, sawing occurs with the
upper edge of the saw bar from below
upwards. The saw chain thus pushes the
device backwards towards the user. If the
saw bar twists, the device can fly towards the
user with great force.
The leveraging effect will push the saw bar
down making the sawing work easier.
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 bar will make contact with
the wood and there will thus be a kickback
(► Risk of kickback! – p. 60).
Felling a tree
DANGER! Risk of injury! Felling
and delimbing work may only be per-
formed by trained people! There is a
risk of fatal injuries!
