Reduced starting current
The electronic reduced starting current limits the
power consumption when switching the tool on and
enables operation from a 13 ampere fuse.
Speed preselection (GWS 15-125 CIEH/GWS 15-125 CITH)
The required speed can be preselected with the thumbwheel 3 (also while running).
The data in the following table are recommended values.

Operating Instructions
Exercise caution when cutting slots in struc-
tural walls; see Section "
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.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
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 temperatures
than conventional sanding sheets.
Cutting Metal
For cutting metal, always work with the pro-
tection guard for cutting 13.
When cutting, work with moderate feed, adapted to
the material being cut. Do not exert pressure onto the
cutting disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting
discs by applying sideward pressure.

Constant Electronic Control
Constant electronic control holds the speed constant
at no-load and under load, and ensures uniform work-
ing performance.

Information on
Cutting Stone
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 20.
The machine may be used only for dry cut-
ting/grinding.
For cutting stone, it is best to use a diamond cutting
disc. As a safety measure against jamming, the cutting
guide with dust extraction protection guard 20 must
be used.
Operate the machine only with dust extraction and
additionally wear a dust protection mask.
The vacuum cleaner must be approved for the extrac-
tion of masonry dust. Bosch provides suitable vacuum
cleaners.

The machine must
always work in an up-
grinding motion. Oth-
erwise, the danger
exists of it being
pushed uncon-
trolled out of the cut.
When cutting profiles
and square bar, it is
best to start at the
smallest cross sec-
tion.
