• Keep the product only on the insulated grip-

ping areas, when operated, during which the
application tool can hit concealed electricity
cables or the mains cable of the product.

Contact with a live cable also energises the metal
parts of the product and lead to an electric shock.

• Keep the power cable away from rotating

parts.

If you lose control, the power cable may

be severed or get caught, and your hand or arm
could be drawn into rotating components.

• Never set the machine down until the applica-

tion tool has come to a complete standstill.

Rotating application tools can become hooked
into the shelf, causing you to lose control of the
machine.

• Never allow the machine to run while carrying

it.

Incidental contact may cause the rotating

application tool to become caught in your cloth-
ing; in this case the application tool may inflict
severe cuts.

• Regularly clean the ventilation slits of your

machine.

The cooling air fan sucks the dust into

the machine housing, and excessive dust depos-
its can cause electrical hazards.

• Do not operate the machine in the vicinity of

combustible materials.

Sparks may ignite

these materials.

• Do not use application tools that require liq-

uid cooling.

Water or other liquid coolants can

cause (lethal) electric shocks.

Cause and prevention of backlash

A backlash is a sudden reaction to the jamming
or catching of a rotating disc, a supporting disc, a
brush or another accessory. Jamming or catching
causes an almost immediate standstill of the
rotating accessory, which as a counter-reaction
causes an uncontrolled machine to accelerate
round the clamping point in the opposite direction
of rotation as the accessory. If, for example, a
sanding disc is jammed or caught by the work-
piece, the disc with the edge at the clamping
point can dig into the surface of the workpiece
and cause it to jump or be flung out. The disc can
either jump towards or away from the user,
depending on the direction of rotation of the disc
at the clamping point. Sanding discs can break
while doing so. A backlash is the result of misuse
of the machine and/or wrong working method or
operation, and can be avoided by correctly
observing the following safety precautions.

• Always hold the machine firmly and position

your body and arms such that you can con-
trol the forces of a potential backlash.

For

optimal control of backlash or reaction torque
when starting up, use the additional handle, if
enclosed. The user can control reaction torques
or backlash if suitable precautionary measures
are taken.

• Never put your hand near rotating application

tools.

Application tools may hit back over your

hand.

• Never take up a position within the area in

which the machine will move in the event of a
backlash.

A backlash will accelerate the

machine in the opposite direction of the disc at
the clamping point.

• Be particularly careful when working in cor-

ners, on sharp edges etc.

Prevent the applica-

tion tool from jumping back and being caught.
Corners, sharp edges or jumping back tend to
cause the rotating tool to get caught, resulting in
loss of control or backlash.

Special safety instructions for fine sanding

• Do not use oversized sanding discs for fine

sanding. When selecting the sanding discs,
follow the manufacturer’s information.

A disc

that is too large and juts out beyond the sanding
wheel poses a risk of cuts and can lead to catch-
ing, disc breakage or backlash.

Additional safety instructions

• Keep a firm hold of the machine with both

hands while working and make sure you are
standing firmly.

The machine is more safely

guided using two hands.

•

If explosive or self-igniting materials arise during
sanding, make sure to observe the processing
information of the manufacturer.

• Warning – risk of fire! Avoid overheating of

the sander and the material being processed.
Always empty the dust container before
breaks.

Grinding dust in the dust container (or in

the filter of the suction unit) can automatically
ignite in unfavourable conditions.

• Inform yourself with regard to the surface to

be sanded and the dusts and vapours poten-
tially arising. If in any doubt, do not inhale
even small amounts of arising dusts or
vapours.

Harmful/toxic dusts may arise when

sanding certain surfaces (various metals, miner-
als or woods as well as weather protection coat-
ings), which can cause severe allergic reactions
or serious illness. Do not inhale these dusts and
vapours and avoid contact. Materials containing
asbestos may only be processed by specialists.

• Keep your workplace clean.

Mixed contamina-

tion caused by dissimilar materials is particularly
hazardous. Light metal dust (e.g. aluminium) can
easily ignite or explode.

• Do not use the electrical tool if the cable is

damaged. Never touch a damaged cable and
remove the mains plug immediately.

Dam-

aged cables increase the risk of electric shock.

• Avoid overheating the product and work-

piece.

Excessive heat can damage the tool and

the product.

• Keep the handles dry and free from grease.
