accessories must be within the specified 
size range of the machine. Accessories with 
incorrect dimensions cannot be sufficiently 
protected or controlled.
The bore diameter of discs, fl anges, support 

–

plates and all other accessories must fi t the 
machine spindle exactly. Accessories with an 
unsuitable diameter are out of round, vibrate 
excessively and lead to loss of control.
Do not use damaged accessories. Before use, 

–

always check accessories such as sanding pads 
for nicks or cracks and check support plates 
for cracks and excessive wear. Every time the 
machine 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 application, use a shield 
or protective goggles. If practical, wear a 
breathing mask, ear protectors, safety gloves 
and a work apron suitable to protect against 
impact 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. 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.
Always hold the machine by the insulated 

–

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 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.
Clean the air vent slits 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 combustible 

–

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 catch-
ing 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 jam-
ming 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 ob-
serving the following precautionary measures. 

–

your body and arms such that you can control 
any kickback force. Always use the auxiliary 
handle, if included in the delivery, to ensure 
optimum control over kickbacks or reaction 
torques during start-up. The user can control 
reaction torques 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 a kickback. 
A kickback accelerates the machine in the 
direction of rotation opposed to the disc at the 
jamming point.
Take extra care when working in corners, on 

–

sharp edges, etc. Avoid kickbacks and prevent
