Test run!
Check the grinding tool before use. The
grinding tool must be flawlessly mounted
and be able to rotate freely. Perform a test
run of at least 30 seconds without load. Do
not use damaged, out-of-round or vibrating
grinding tools.
Starting Current Limiting
(Type J)
As a result of soft starting, a 13-A fuse is
adequate.
A machine without reduced starting cur-
rent requires higher fuse protection (use
at least a 13 A time-delay fuse).
■ Clamp the workpiece if it does not remain
stationary due to its own weight.
■ Do not load the machine so heavily that it
comes to a standstill.
■ Roughing and cutting discs become very
hot while working; do not touch until they
have cooled.
Rough Grinding
With an approach angle of 30° to
40°, the best roughing results can
be achieved. Move the machine
back and forth with moderate pres-
sure. In this manner, the work piece
will not become too hot, does not
discolour and no ridges are formed.
Never use a cutting disc for roughing.
Flap disc
With the flap disc (optional extra), curved sur-
faces and profiles (contour sanding) can be
worked.
Flap discs have a considerably higher service life
than sanding sheets, lower noise level and lower
sanding temperatures.
Cutting
When cutting, do not press, tilt or
oscillate. Work with moderate ad-
vancing that is adapted to the mate-
rial being worked.
Do not brake coasting cutting disks
with side pressure.
Important is the di-
rection in which cut-
ting is performed.
The machine must
always work opposite
to the direction of ro-
tation. Therefore,
never move the ma-
chine in the other di-
rection! Otherwise,
the danger exists of it
being pushed un-
controlled out of the
cut.
Cutting grinder Stand
With the cutting grinder stand 25 (optional extra),
work pieces of the same length can be cut at an-
gles of 0 to 45°.
The safety notes and operating instructions in the
respective operating instructions manual of the
angle grinder are to be strictly observed. Use only
original Bosch grinder stands.
