For Your Safety
Working safely with this ma-
chine is possible only when the
operating and safety information
are read completely and the in-
structions contained therein are
strictly followed. In addition, the
general safety notes in the enclosed booklet
must be observed. Before using for the first
time, ask for a practical demonstration.
Wear protective glasses and hearing protec-
tion.
Wear additional protection equipment for your
safety, such as protective gloves, sturdy
shoes, hard hat and apron.
The dust that is produced while working can be
detrimental to health, inflammable or explo-
sive. Suitable safety measures are required.
Examples: Some dusts are regarded as carci-
nogenic. Use suitable dust/chip extraction and
wear a dust respirator.
Dust from light alloys can burn or explode. Al-
ways keep the workplace clean, as blends of
materials are particularly dangerous.
If the mains cable is damaged or cut through
while working, do not touch the cable but im-
mediately pull the mains plug. Never use the
machine with a damaged cable.
Connect machines that are used in the open
via a residual current device (RCD) with an ac-
tuating current of 30 mA maximum. Do not op-
erate the machine in rain or moisture.
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
Always direct the cable to the rear away from
the machine.
Always switch the machine off and wait until it
has come to a standstill before placing it down.
For power outage or when the mains plug is
pulled, unlock the On/Off switch immediately
and turn it to the off position. This prevents un-
controlled restarting.

The machine must be used only for dry cutting/
grinding.
For all work with the machine, the auxiliary
handle must be mounted.
Hold the power tool only by the insulated
gripping surfaces, when performing an op-
eration where the cutting tool may run into
hidden wiring or its own cord.
Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the op-
erator.
Use appropriate detectors to determine if
utility lines are hidden in the work area or
call the local utility company for assist-
ance.
Contact with electric lines can lead to fire and
electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes
property damage or may cause an electric
shock.
For work with grinding or cutting discs, the pro-
tection guard 5 must be mounted. For work
with the rubber sanding plate 12 or with the
cup brush 15/disc brush/flap disc, the hand
guard 11 (accessory) is to be mounted.
Use dust extraction when working with stone.
The vacuum cleaner must be approved for ma-
sonry dust. When cutting stone, use the cutting
guide.
Do not work with materials containing asbes-
tos.
Use only grinding tools with a permissible
speed at least as high as the no-load speed of
the machine.
Check grinding tools before use. The grinding
tool must be properly mounted and turn freely.
Perform a test run for at least 30 seconds with-
out load. Do not use damaged, out-of-round or
vibrating grinding tools.
Protect the grinding tool from impact, shock
and grease.
Apply the machine to the workpiece only when
switched on.
Keep hands away from rotating grinding tools.
Pay attention to the direction of rotation. Al-
ways hold the machine so that sparks and
grinding dust fly away from the body.
