Always direct the cable to the rear away from
the machine.
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.
Use only grinding tools with a permissible
speed at least as high as the no-load speed of
the machine.
Observe the manufacturer's instructions for
mounting and using grinding tools.
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.
Keep hands away from rotating grinding tools.
Do not clamp the machine in a vice.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
Do not work with materials containing asbes-
tos.
Apply the machine to the workpiece only when
switched on.
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).
Always switch the machine off and wait until it
has come to a standstill before placing it down.
Caution! The grinding tool runs on after the
machine is switched off.
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 Grinding Tools
(Accessories – see figure
Before any work on the machine itself, pull
the mains plug.
Use only grinding tools with a permissible
speed at least as high as the no-load speed
of the machine.
Clean the parts to be mounted. Hold the grinder
spindle 3 on the spanner surfaces with a 17 mm
open-ended spanner.
Loosen clamping nut 2 using an open-jawed
spanner.
Insert the clamping shaft of the grinding tool to
the stop into the collet chuck.
Tighten clamping nut 2.
The grinding tools must run completely concentri-
cally. Do not continue to use damaged grinding
tools that are out of balance. If the grinding tools
are out of balance they should be replaced. Treat
with a whetstone or change. Using a whetstone
any particular special shape can be produced out
of the basic forms of the grinding disc.
Other tools such as, for example, brushes and
files can be used. The speed is to be reduced to
the permissible speed for this tool.
Test run!
Check the grinding tool before use. The
grinding tool must be properly mounted
and rotate freely. Perform a test run of at
least 30 seconds without load. Do not use
damaged, out-of-round or vibrating grind-
ing tools.
