• Kickback can occur when the tip of the guide bar
touches an object or when the timber bends and
the saw-chain becomes caught in the cut.
• Contact with the guide bar tip can, in some cas-
es, lead to an unexpected backwards reaction in
which the guide bar is thrown up and in the direc-
tion of the operator.
• If the saw-chain becomes caught at the top of the
guide bar, the guide bar can quickly kick back to-
wards the operator.
• Each of these reactions can cause you to lose con-
trol over the saw and potentially to get severely in-
jured. Do not exclusively trust the safety devices
built into the chainsaw. As the user of a chainsaw,
you should take dierent measures to work acci-
dent and injury free.
Kickback is the consequence of incorrect or erratic
use of the machine. It can be prevented by appropri-
ate safety measures such as described below:
• Hold the saw with both hands, ensuring

If appropriate measures are taken, the operator
can control kickback forces. Never let go of the
chainsaw.
• Avoid an abnormal body posture and do not
saw above shoulder height. This prevents ac-
cidental contact with the tip of the guide bar and
it enables better control of the chainsaw in unex-
pected situations.
• Always use replacement guide bars and saw-

m WARNING
• Rotational kick-back (g. 28)
A = kick-back distance / B = kick-back reaction
zone
• Kick-back and kick-back reactions when there is
an impact/blockage (g. 29)
A = pull / B = xed objects / C = press
• In order to prevent kick-back reactions, position
the wood to be sawn directly at the claw stop. Use
the claw stop as the rotation point when sawing.
11 THE THROTTLE TRIGGER INTERLOCK pre-
vents accidental acceleration of the motor. The throt-
tle can be activated only when the throttle trigger in-
terlock is pressed.
10 THE ON/OFF SWITCH immediately stops the mo-
tor when it is switched o. The stop switch must be
turned to ON to start the motor (again).
16 CHAIN PROTECTOR applied when the motor is
at a standstill and prevents the risk of cutting injuries
due to the chain teeth.
20 THE CHAIN CATCHER reduces the risk of inju-
ry if the saw-chain breaks or slips when the motor
is running. The chain catcher is designed to catch a
ailing chain.
m NOTICE
Familiarise yourself with the saw and its components.
• When the saw is running, keep all body parts
