back caused by a jammed cut-off wheel. Large
workpieces tend to sag under their own weight.
Workpieces must be supported on both sides of the
wheel, near the cut and also along the edge.
h) Use extra caution when making a "pocket
cut" into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
3.4 Safety Warnings Specific for Wire Brush-
ing Operations:
a) Be aware that wire bristles are lost by the
brush even during ordinary operation. Do not
overstress the wires by applying an excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) Before using a brush, allow it to run for at
least one minute at operating speed. Make sure
that no one is positioned in front of or in line
with the brush during this time. Loose wire bris-
tles may be released during the running-in time.
c) Direct the rotating brush away from you.
When working with these brushes, remember that
small particles and tiny wire bristles may be ejected
at high speed and may penetrate the skin.
3.5 Additional Safety Instructions
WARNING – Always wear protective
goggles.
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Abrasives must be stored and handled with care in
accordance with the manufacturer's instructions.
Never use parting grinder discs for roughing work.
Do not apply pressure to the side of parting grinder
discs.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be supported adequately.
Keep hands away from the rotating tool! Remove
swarf and similar material only when the machine is
at a standstill.
Prior to use, ensure that the coated abrasive is
properly fitted and secured. Run the tool in idling for
60 seconds in a safe position and bring to a stand-
still immediately if there are significant vibrations or
if other deficiencies are determined. If such a situa-
tion occurs, check the machine to determine the
cause.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inflammable substances.
Endangered areas must be protected with flame-
resistant covers. Make sure that fire-risk areas are
always provided with suitable fire extinguishers.

Some dust created by power
WARNING
sanding, sawing, grinding,
drilling, and other construction activities
contains chemicals known to cause cancer,
birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and
other masonry products, and
• Arsenic and chromium from chemicallytreated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic
particles.
Materials emitting dusts or vapours that may be
harmful to health (e.g. asbestos) must not be
processed.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first disconnect the
power tool from the mains supply (use non-metallic
objects) and avoid damaging internal components.
Damaged, eccentric or vibrating tools must not be
used.
For safety reasons, always ensure the rubber
sleeve is fitted while you work (4).
Pull the plug out of the plug socket before any
adjustments, conversions or servicing are
performed.
During machining, of metals in
particular, conductive dust can form
deposits inside the machine. This can lead to the
transfer of electrical energy onto the machine
housing. This can mean a temporary danger of
electric shocks. This is why it is necessary when the
machine is running to blow compressed air through
the rear ventilation slots of the machine regularly,
frequently and thoroughly. The machine must be
held firmly in this case.
We recommend using a stationary extractor system
and connecting a residual current circuit-breaker
(FI) upstream. When the machine is shut down via
the FI circuit-breaker, it must be checked and
cleaned. For information on cleaning the motor, see
chapter 7. Cleaning.
