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 can be used only for dry sanding.
For all work with the machine, the auxiliary
handle must be mounted. For work with the
rubber sanding plate 11 or with the cup
brush 5/disc brush, mount the hand guard 3
(accessory).
Use dust extraction when working with stone.
The vacuum cleaner must be approved for ma-
sonry dust.
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).
Observe the manufacturer's instructions for
mounting and using grinding tools.
Caution! The grinding tool runs on after the
machine is switched off.
Do not clamp the machine in a vice.
Never allow children to use the machine.
Bosch is only able to ensure perfect operation
of the machine if the original accessories in-
tended for it are used.
Mounting the
Protective Devices
Before any work on the machine itself, pull
the mains plug.

Auxiliary Handle

For all work with the machine, the auxiliary
handle must be mounted.
Screw the auxiliary handle 4 into the head of the
machine according to the working method.
With the handle bracket 20, the auxiliary handle 4
can be mounted above the machine head in a
manner favourable to the centre of gravity.
Bring the handle bracket 20 into the required po-
sition according to the working manner and screw
tight. The 12-angled profile at the thread 2 en-
sures twist-free fastening.

Hand Guard

When working without the handle bracket 20, the
hand guard should be mounted. The hand
guard 3 is fastened with the auxiliary handle 4.

Protective Cap

The machine head warms up when working with
the machine. Depending on the handling of the
machine, the protective cap 12 can be used as a
contact protector.
Attach the protective cap 12 onto the machine
head and fasten using the enclosed fastening
screw 13 as well as with the auxiliary handle 4.
