• 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 different 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 thumbs
and fingers clasp the handles of the chainsaw.
Position your body and arms in such a way that
you can withstand kickback forces. If appropriate
measures are taken, the operator can control kick-
back forces. Never let go of the chainsaw.
• Avoid an abnormal body posture and do not saw
above shoulder height. This prevents accidental
contact with the tip of the guide bar and it ena-
bles better control of the chainsaw in unexpected
situations.
• Always use replacement guide bars and saw-
chains specified by the manufacturer. Incorrect re -
placement guide bars and saw-chains can cause
breaking of the chain and/or kickback. (see chap-
ter 15)
• Follow the manufacturer‘s instructions concerning
sharpening and maintenance of the saw-chain.
Over-reduction of depth limiters increases kick-
back tendency.

WARNING
Please pay attention to the following:
• Rotational recoil (Fig. 28)
• A = kickback distance / B = kickback reaction zone
• Rebound and Retraction Reactions on Impact /
Blockage (Fig. 29)
• A = Drag / B = Fixed objects / C = Press
• To avoid withdrawal reactions, position the wood to
be sawn against the claw stop. Use the claw stop
as a fulcrum when sawing.
5.6 Safety notices for maintenance/storage
Have your machine repaired by qualified specialists
and only with original spare parts. This ensures the
safety of the machine.
1. Before use, always visually check the tool for
wear and tear or damage. Replace worn or dam-
aged components and bolts. Tighten all nuts,
bolts and machine screws to ensure that the
equipment is in a safe operating condition.
2. Regularly check the fuel system for leakage or
signs of abrasion, for example from porous fuel
lines, loose or missing clamps and damage to the
tank or the tank lid. All faults must be resolved
before use.
THE ON/OFF SWITCH (10) immediately stops the
motor when it is switched off. The stop switch must
be turned to ON to start the motor (again).
THE CHAIN CATCHER (20) reduces the risk of in-
jury if the saw-chain breaks or slips when the motor
is running. The chain catcher is designed to catch a
flailing chain.

NOTICE
Familiarise yourself with the saw and its components.
5.5 Warning notices for chainsaws
• When the saw is running, keep all body parts away
from the saw-chain. Before starting the saw, en-
sure that nothing touches the saw-chain. When
working with a chainsaw, a moment of careless-
ness can cause clothing or body parts to be caught
by the saw-chain.
• Do not work with this chainsaw on a tree unless
you are especially trained for this. In the event of
improper use of a chainsaw on a tree, there is a
risk of injury.
• When cutting a branch under tension, expect it
to spring back. When the tension is released, the
branch can hit the operator and/or take away con-
trol of the chainsaw.
• Be particularly careful when cutting undergrowth
and young trees. Thin material can get caught in
the saw-chain and be ejected in your direction or
make you lose your balance.
• Carry the chainsaw by the front handle with the
saw-chain not moving and the guide bar pointing
backwards. During transport and storage of the
chainsaw always attach the safety cover. Careful
handling of the chainsaw reduces the likelihood of
accidentally touching the running saw-chain.
• Follow the instructions for lubrication, chain ten-
sion and replacement of accessories. An improp-
erly tensioned or lubricated chain can either break
or increase the kickback risk.
• Keep handles dry, clean and free from oil and
grease. Greasy, oily handles are slippery and
cause loss of control.
Causes and prevention of kickback:
• 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.
