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
maximum speed.
Damage accessories usually break completely
during this test time.
Wear personal protective equipment. Depending on the applica-
tion, use a shield or protective goggles. If practical, wear a brea-
thing mask, ear protectors, safety gloves and a work apron suit-
able to protect against impact or small sanding or workpiece
parts.
The protective goggles must be capable of blocking flying debris
caused by the various work operations. The breathing mask or device
must be capable of filtering particles generated during work.
Continuous 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.
Keep the power cable away from rotating 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 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.
Never operate the machine near combustible materials.
Sparks can
ignite these materials.
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 accelerated around the jamming point in a
direction of rotation opposed to the accessory. 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 measures.
