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.
Reduced Starting Current
(PWS 20-230 J)
As a result of soft starting, a 13 A fuse is
adequate.
A machine without reduced starting current
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 strain the machine so heavily that it
comes to a standstill.
Grinding and cutting discs become very
hot while working; do not touch until they
have cooled.
Rough Grinding
The best roughing results are
achieved when setting the machine
at an angle of 30° to 40°. Move the
machine back and forth with mod-
erate pressure. In this manner, the
workpiece will not become too hot,
does not discolour and no grooves
are formed.
Never use a cutting disc for roughing.
Flap Disc
With the flap disc (accessory), curved surfaces
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, jam or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being machined.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.
The direction in
which the cutting is
performed is impor-
tant.
The machine must
always work in an
up-grinding motion.
Therefore, never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed uncon-
trolled out of the cut.
Grinder Stand
With the grinder stand 26 (accessory), work-
pieces can be cut at angles of 0 to 45° at the
same lengths.
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.
