Safety instructions for all operations - Kickback
and related warnings
Kick-back is the sudden reaction resulting from a
caught or jammed rotating insert tool, such as a grind-
ing disc, grinding wheel, wire brush, etc. Catching or
jamming results in the rotating insert tool stopping
abruptly.
As a result, an uncontrolled electric tool is accelerated
against the direction of rotation of the tool attachment
at the blocking point.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface
of the material causing the wheel to climb out or kick
out. The wheel may either jump toward or away from
the operator, depending on direction of the wheel's
movement at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of incorrect or deficient use of
the electrical tool.
It can be prevented by suitable precautionary meas-
ures, as described in the following.
a) Hold the power tool firmly in both hands and
position your body and arms so they can ab-
sorb the force of a kickback. Always use the
additional handle, if available, so that you
have the maximum possible control over the
kickback force or reaction forces at full speed.
By taking adequate precautions, the operator can
stay in control of the kickback and reaction forces.
b) Never hold your hand close to a rotating ac-
cessory tool. The accessory tool could jump out
of your hand if there is a kickback.
c) Avoid having any part of your body in the re-
gion in which the power tool is likely to move
in event of a kickback. The kickback will force
the power tool in the opposite direction to the di-
rection of rotation of the sanding disc at the block-
age.
d) Take special care when working near corners,
sharp edges, etc. Avoid allowing the accesso-
ry tool to bounce back from the workpiece or
jam. The rotating tool attachment tends to jam at
corners, sharp edges or when it bounces back.
This causes a loss of control or kick-back.
e) Do not use chains or toothed saw blades. Such
accessories often cause a kickback or loss of con-
trol over the power tool.
Safety instructions for sandpaper grinding
a) Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper. Larg-
er sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Additional safety instructions
a) Connect a vacuum cleaner to the supplied
adapter before starting your operations.
b) ATTENTION! Keep away sanding dust from open
fire. Dust may be explosive.
c) Always wear safety glasses and a dust protec-
tion mask when sanding, in particular during
overhead work and when processing critical
materials!
When sanding certain materials (e. g. lead paint,
certain types of wood and metal) harmful or nox-
ious dust may be generated.
Touching or breathing in such dust may imply risks
for the operator or bystanders.
Notes regarding vibration and noise emissions
Keep the noise level and vibration to a minimum!
1. Only use power tools which are free of defects.
2. Maintain and clean the power tool on a regular
basis.
3. Adjust your way of working to the power tool.
4. Do not force the power tool.
5. Have your power tool checked if necessary.
6. Switch off the power tool if it is not in use.
Residual risks
Even when this power tool is operated properly, re-
sidual risks still remain. The following hazards may
arise in connection with the design and construction
of this power tool:
a) Damage to health resulting from hand/arm vibra-
tion if the device is used over an extended pe-
riod of time or if it is not properly operated and
maintained.
b) Injury and property damage caused by insert tools
being flung around and unexpectedly out of/from
the electric tool due to sudden damage, wear or
improper attachment.
c) Burns and cuts if the accessories are touched di-
rectly after use and/or with your bare skin.
