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 op-
erator (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 condi-
tions 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 kickback
forces. Kickback forces can be con-
trolled by the operator, if proper pre-
90
cautions 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) or above shoulder
height. Do not lean over too far during
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 sawing
small bushes and branches. The thin
branch thicket can snag in the saw and
whip in your direction or make you un-
balanced.
• 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!
