Protective measures against
kickbacks when working with
the chain saw
Caution kickbacks! In the event
of a kickback, the user will feel a
powerful blow from the device.
As a consequence, he/she could
lose control over the device and
be seriously injured. A kickback
is avoided through care and cor-
rect technique.

•
Kickback may occur when the nose or
tip of the guide bar touches an object,
or when the wood closes in and pinch-
es the saw chain in the cut (cf. fig. b).
•
Tip contact in some cases may cause
a sudden reverse reaction, kicking the
guide bar up and back towards the
operator (cf. fig. a).
•
Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back towards the operator.
Kickback is the result of tool misuse and/
or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:
•
Maintain a firm grip, with thumbs
and fingers encircling the chain
saw handles, with both hands on
the saw and position your body
and arm to allow you to resist kick-
back forces. Kickback forces can be
controlled by the operator, if proper
precautions are taken. Do not let go of
the chain saw.
•
Do not overreach and do not cut
above shoulder height. This helps
prevent unintended tip contact and
enables better control of the chain
saw in unexpected situations.
•
Only use replacement bars and
chains specified by the manufac-
turer. Incorrect replacement bars and
chains may cause chain breakage
and/or kickback.
Follow the manufacturer´s sharpen-
•
ing and maintenance instructions
for the saw chain. Decreasing the
depth gauge height can lead to in-
creased kickback.
•
Do not saw with the point of the
blade
(cf. fig. b)
height. Do not lean over too far dur-
ing the sawing operation.
•
Ensure that there are no objects ly-
ing around on the ground that you
can trip over.
•
Place the claw stop securely with
every cut and do not begin with the
sawing before this.
•
Be extremely careful during saw-
ing small bushes and branches.
The thin branch thicket can snag in
the saw and whip in your direction or
make you unbalanced.
•
Do not cut wood that is lying on the
ground.
•
Pay attention to a possible spring-
back during the sawing of a branch
which is under stress, if the stress
force of the wood is suddenly re-
leased. Danger of injury exists.
•
In the event that the cutting attach-
ment becomes jammed or stuck
in the branches, do not attempt to
free the equipment with the use of
force. Switch off the equipment im-
mediately and restart it only after
clearing the blockage. There is a
risk of injury!
