maximum speed specifi ed on the machine.
Accessories that rotate faster than the
permissible level can rupture.
- The outside diameter and the thickness of
the accessory must be within the specifi ed
size range of the machine. Accessories
with incorrect dimensions cannot be suf-
fi ciently protected or controlled.
- The bore diameter of discs, fl anges, sup-
port plates and all other accessories must
fi t the machine spindle exactly. Accesso-
ries with an unsuitable diameter are out
of round, vibrate excessively and lead to
loss of control.
- Do not use damaged accessories. Check
accessories such as wire brushes for loose
or broken wires before using. Every time
the machine is dropped, check the machine
and accessories for damage, or install un-
damaged 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 maximum speed. Damage ac-
cessories usually break completely during
this test time.
- Wear personal protective equipment. De-
pending on the application, use a shield
or protective goggles. If practical, wear a
dust mask, ear protection, safety gloves
and a work apron suitable to protect
against impact or small sanding or work-
piece parts. The protective goggles must
be capable of blocking fl ying debris caused
by the various work operations. The dust
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 acces-
sories can fl y off and cause injury outside
the immediate work area.
- 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 area, causing you to
lose control of the machine.
- Never allow the machine to operate while
carrying it at your side. The rotating tool
can catch on your clothing by accident and
cause serious cutting injuries.
- Clean the cooling air openings on your
machine 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 combus-
tible 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 coun-
ter-reaction, an out-of-control machine is
accelerated around the jamming point in
a direction of rotation opposed to the ac-
cessory. If, for example, a sanding disc is
jammed or caught by the workpiece, the disc
circumference can dig into the workpiece
surface at the jamming point, causing the
disc to be expelled. The disc can either fl y
towards or away from the user, depending
on the direction of rotation of the disc at the
jamming point.
This can also cause sanding discs to break.
A kickback is the result of misuse of the
machine and/or incorrect method of work
or operation and can be avoided by closely
observing the following precautionary meas-
ures.
- Always hold the machine fi rmly and po-
sition your body and arm such that you
can control any kickback force. Always
use the additional handle, if included in
the delivery, to ensure optimum control
over kickbacks or reaction torques during
start-up. The user can control reaction tor-
ques or kickbacks if suitable precautionary
measures are taken.
- Never place your hands near rotating tools.
Tools can kick back over your hand.
- Never position your body in the area in
which the machine moves in the event of
