ing instructions are not observed, this can
result in an electric shock, fi re and/or seri-
ous injury.
- Do not use this machine to perform
work such as roughing, brushing, pol-
ishing or disc sanding. Performing tasks
for which the machine is not designed can
create hazards and lead to injury.
- Never use accessories that were not
specially developed and intended for
this machine. Just because an accessory
part can be fi tted on your machine does
not guarantee danger-free operation.
- The permissible rotational speed of the
accessory must be at least as high as
the maximum speed specifi ed on the
machine. Accessories that rotate faster
than the permissible level can rupture.
- The outside diameter and the thick-
ness of accessories must be within the
specifi ed size range of the machine.
Accessories with incorrect dimensions can-
not be suffi ciently protected or controlled.
- The bore diameter of discs, fl anges,
support plates and all other acces-
sories must fi t the machine spindle
exactly. Accessories with an unsuitable
diameter are out of round, vibrate exces-
sively and lead to loss of control.
- Do not use damaged accessories. Be-
fore use, always check accessories such
as sanding pads for nicks or cracks and
check support plates for cracks and
excessive wear. Every time the ma-
chine is dropped, check the machine
and accessories for damage, or install
undamaged accessories. Following the
check and assembly of accessories,
ensure that all persons are beyond
the rotating range of the tool and run
the machine for one minute at maxi-
mum speed. Damage accessories usually
break completely during this test time.
- Wear personal protective equipment.
Depending on the application, use a
shield or protective goggles. If prac-
tical, wear a breathing mask, ear
protectors, safety gloves and a work
apron suitable to protect against im-
pact or small sanding or workpiece
parts. The protective goggles must be
capable of blocking fl ying debris caused by
the various work operations. The breathing
mask or device must be capable of fi ltering

particles generated during work. Continu-
ous exposure to loud noise can cause loss
of hearing.
- Ensure that persons standing near the
machine are at a safe distance from
the work area. All persons in the work
area must wear personal protective
equipment. Parts of the workpiece or
broken accessories can fl y off and cause
injury outside the immediate work area.
- Always hold the machine by the insu-
lated handles if you intend to perform
work that may pose a risk of cutting
into hidden power cables or your own
machine cable. Contact with live cables
transfers an electric current to metallic
machine components and causes electric
shocks.
- Keep the power cable away from rotat-
ing parts. If you lose control, the power
cable could be cut or become stuck and
your hand or arm could be drawn into the
rotating parts.
- Never set the machine down until the
tool has stopped completely. Turning
tools can catch on the storage surface,
causing you to lose control of the ma-
chine.
- Never allow the machine to operate
while carrying it at your side. The rotat-
ing tool can catch on your clothing by ac-
cident and cause serious cutting injuries.
- Clean the air vent slits on your ma-
chine on a regular basis. The cooling air
fan sucks the dust into the machine and
excessive deposits of metal dust can result
in electrical hazards.
- Never operate the machine near com-
bustible materials. Sparks can ignite
these materials.
- Never use tools that have to be liquid-
cooled. Water and other liquid coolants can
cause potentially fatal electric shocks.
Cause and prevention of kickbacks
A kickback is a sudden reaction to jamming
or catching of a rotating disc, a support
plate, a brush or other accessory. Jamming
or catching results in a rapid standstill of the
rotating accessory, whereby, as a counter-
reaction, an out-of-control machine is accel-
erated around the jamming point in a direc-
tion of rotation opposed to the accessory.
If, for example, a sanding disc is jammed or
caught by the workpiece, the disc circumfer-
