Working Advice
Exercise caution when cutting slots in
structural walls; see Section "Information
on Structures ".
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.
After heavily straining the power tool, con-
tinue to run it at no-load for several minutes
to cool down the cutting/grinding tool.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Do not use the power tool with a cut-off
stand.
Bosch Power Tools
Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a test
run for at least one minute with no load. Do
not use damaged, out-of-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
Accessory
Sanding disc
Cup brush, sanding disc
Grinding disc
Grinding disc
Cutting disc and cutting guide
(Cutting masonry/stone is permitted
only with use of the cutting guide)
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when
setting the machine at an angle of 30° to 40°.
Move the machine back and forth with moderate
pressure. In this manner, the workpiece will not
become too hot, does not discolour and no
grooves are formed.
Flap Disc
With the flap disc (accessory), curved surfaces
and profiles can be worked.
Flap discs have a considerably higher service
life, lower noise levels and lower sanding tem-
peratures than conventional sanding sheets.
Cutting Metal
For cutting metal, always work with the pro-
tection guard for cutting 13.
