m)Never allow the machine to operate while carry-
ing it at your side.
The rotating tool can catch on
your clothing by accident and cause serious cutting
injuries.
n) Clean the air vent slits on your machine on a re-
gular basis. The cooling air fan sucks the dust into
the machine and excessive deposits of metal dust
can result in electrical hazards.
o) Never operate the machine near combustible ma-
terials. Sparks can ignite these materials.
p) Never use tools that have to be liquid-cooled.
Water and other liquid coolants can cause potenti -
ally fatal electric shocks.
Cause and prevention of kickbacks
A kickback is a sudden reaction to jamming or cat -
ching 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 workpie -
ce, the disc circumference can dig into the workpiece
surface at the jamming point, causing the disc to be
expelled. The disc can either fly 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.
a) Always hold the machine firmly and position
your body and arms such that you can control
any kickback force. Always use the auxiliary hand -
le, 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 ta -
ken.
b) Never place your hands near rotating tools. Tools
can kick back over your hand.
c) 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.
d) Take extra care when working in corners, on
sharp edges, etc. Avoid kickbacks and prevent the
tool from seizing. Corners, sharp edges or a jump
back tend to cause the rotating tool to catch, thus
leading to a loss of control or a kickback.
Special safety instructions for fine sanding
a) Do not use excessively large sanding discs
when fine sanding. Observe the specifi cations
of the manufacturer when selecting abrasive
discs. A sanding disc that is too large and protru -
des over the sanding pad represents a cutting injury
hazard and can cause catching, disc tears or kick -
backs.
Additional warning notes
a) Hold the machine firmly with both hands and
assume a stable stance when performing work.
Hold the machine with both hands to guide more se -
curely.
b) If potentially explosive or self-igniting dust is
produced during sanding, the processing inst-
ructions of the material manufacturer must be
observed under all circumstances.
c) Harmful/toxic dusts can be produced during
your work (e.g. lead-containing paint, some ty-
pes of wood and metal). Contact with these dusts,
Machine-related safety instructions
a) This machine is designed for sanding.
Please
read all of the safety information, instructions, illust -
rations and descriptions delivered with the machine.
If the following instructions are not observed, this
can result in an electric shock, fire and/or serious in -
jury.
b) Do not use this machine to perform work such
as roughing, brushing, polishing or disc san-
ding. Performing tasks for which the machine is not
designed can create hazards and lead to injury.
c) Never use accessories that were not specially
developed and intended for this machine. Just
because an accessory part can be fitted on your ma -
chine does not guarantee danger-free operation.
d) The permissible rotational speed of the acces-
sory must be at least as high as the maximum
speed specified on the machine. Accessories that
rotate faster than the permissible level can rupture.
e) The outside diameter and the thickness of acces-
sories must be within the specified size range of
the machine.
Accessories with incorrect dimensions
cannot be sufficiently protected or controlled.
f) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the ac -
cessory must fit the locating diameter of the
flange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
g) 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 ac-
cessories for damage, or install undamaged ac-
cessories. Following the check and assembly of
accessories, ensure that all persons are beyond
the rotating range of the tool and run the machi-
ne for one minute at maximum speed. Damage
accessories usually break completely during this test
time.
h) 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 sui-
table 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 de -
vice must be capable of fi ltering particles generated
during work. Continuous exposure to loud noise can
cause loss of hearing.
i) Ensure that persons standing near the machi-
ne 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 fly off and cause injury out -
side the immediate work area.
j) Always hold the machine by the insulated hand-
les 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 trans -
fers an electric current to metallic machine compo -
nents and causes electric shocks.
k) 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.
l) 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.
