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 6 must be mounted. For work
with the rubber sanding plate 20 or with the
cup brush 23/disc brush/flap disc, the hand
guard 18 (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.
■
When grinding metal, flying sparks are pro-
duced. Take care that no persons are endan-
gered. Due to danger of fire, no combustible
materials should be located in the vicinity
(spark flight zone).
■
Be careful when cutting grooves, e. g. in struc-
tural walls: See Information on Structures.
■
Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.
