To switch off the power tool, release the On/Off switch 4 or,
if it is locked, briefly push down the back of the On/Off switch
4 and then release it.
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 grind-
ing tools. Damaged grinding tools can burst and cause in-
juries.
Kickback stop
(GWS 11-125 CI/GWS 11-125 CIE/GWS 14-125 CI/
GWS 14-125 CIE/GWS 14-125 CIT/GWS 14-150 CI)
In case of a sudden drop in speed, e.g.,
caused by a jammed disc while cutting, the
power supply to the motor is electronically
interrupted.
To restart the operation, switch the
On/Off switch 4 to the Off position and start
the machine again.
Speed preselection (GWS 11-125 CIE/GWS 14-125 CIE/GWS 14-125 CIT)
The required speed can be preselected with the thumbwheel 3 (also while running).
The data in the following table are recommended values.

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, continue to run
it at no-load for several minutes to cool down the acces-
sory.
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.

Restarting Protection
(GWS 11-125 CI/GWS 11-125 CIE/GWS 14-125 CI/
GWS 14-125 CIE/GWS 14-125 CIT/GWS 14-150 CI)
The restarting protection feature prevents uncontrolled re-
starting of the machine after an interruption in the power sup-
ply.
To restart the operation, switch the On/Off switch 4 to the
Off position and start the machine again.
Reduced starting current
(GWS 11-125 CI/GWS 11-125 CIE/GWS 14-125 CI/
GWS 14-125 CIE/GWS 14-125 CIT/GWS 14-150 CI)
The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation
from a 13 ampere fuse.
Constant Electronic Control
(GWS 11-125 CI/GWS 11-125 CIE/GWS 14-125 CI/
GWS 14-125 CIE/GWS 14-125 CIT/GWS 14-150 CI)
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perform-
ance.
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 ma-
chine 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.
