•
Additional signs or other, non BAIER­
specific parts may not be screwed or riveted
onto the motor, handle, gearbox or protec­
tive housing.
This could damage the power tool and cause
malfunctions to occur.
•
Avoid unnecessary noise emissions.

Note and follow the safety and work instruc­
tions for the accessories used.
Kickback and corresponding safety
instructions
Kickback is the sudden reaction caused by a
rotating insert tool, such as the cutter, that gets
caught or is blocked. Pinching or blocking re-
sults in the abrupt stopping of the rotating cut-
ting tool. This causes an uncontrolled power
tool to be accelerated against the direction of
rotation of the insert tool at the blocking point.
For example, if a cutter gets stuck in the work-
piece or becomes blocked, the edge of the cut-
ter that is immersed in the workpiece can get
caught and therefore break out the cutter or
cause kickback. The cutter then moves towards
or away from the person using the tool, depend-
ing on the direction of rotation of the cutter at the
blocking point. At the same time, the cutter can
also break.
Kickback is the consequence of incorrect or
faulty use of the power tool. It can be prevented
by taking suitable precautions, as described in
the following.
•
When switching on and while working with
the power tool, hold onto it tightly at both
handles and place your body and arms in a
position in which they can absorb the kick­
back forces or reaction torque on starting
up. Always put the machine down firmly on
both rollers.
The person using the tool can control the kick-
back and reaction forces by taking suitable pre-
cautions.
•
Avoid blocking of the cutter caused by
pressing too hard or feeding too fast. Do not
make any excessively deep cuts.
Overloading the cutter increases the stresses
on it and its susceptibility to canting or blocking
and therefore the possibility of kickback or cut-
ter breakage.

•
Never place your hand near rotating cutting
tools.
The cutting tool can move across your hand dur-
ing kickback.
•
Keep your body clear of the area in which
the power tool would move in the event of
kickback.
The kickback drives the power tool in the oppo-
site direction to the movement of the cutter at
the blocking point.
•
Take particular care when working in the
area of corners, sharp edges, etc. Prevent
cutting tools from rebounding and sticking
workpiece.
The rotating insert tool tends to get stuck in cor-
ners, sharp edges or if it rebounds. This causes
loss of control or kickback.
•
Do not use a chain ring or toothed sawblade.
Such cutting tools frequently cause kickback or
loss of control of the power tool.
•
If the cutter sticks or you interrupt the work,
switch off the tool and keep it still until the
cutter has stopped moving. Never attempt
to pull the still running cutter out of the cut,
otherwise kickback can occur.
Find out and remove the cause of the sticking.
•
Do not switch the power tool back on while
it is still in the workpiece. Allow the cutter to
reach its full speed first before carefully con­
tinuing with the cut.
Otherwise the cutter can pinch, jump out of the
workpiece or cause kickback.
•
Support slabs, boards or large workpiec­
es to reduce the risk of kickback due to a
jammed cutter.
Large workpieces can sag under their own
weight. The workpiece must be supported on
both side, not only near the cut but also at the
edge.
•
Be especially cautious at "pocket cuts" in
existing walls or other concealed areas.
The plunging cutter can cause kickback when
cutting gas or water pipes, electric cables or oth-
er objects.
