Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
 Hold power tool by insulated gripping surfaces 23 and
auxiliary handle 5 only. The accessory may contact hid-
den wiring or its own cord. Accessory contacting a "live"
wire may make exposed metal parts of the power tool "live"
and shock the operator.
When operating the machine with power from mobile genera-
tors that do not have sufficient reserve capacity or are not
equipped with suitable voltage control with starting current
amplification, loss of performance or untypical behavior can
occur upon switching on.
Please observe the suitability of the power generator being
used, particularly with regard to the mains voltage and fre-
quency.
Switching On and Off
To start the power tool, push the On/Off switch 4 forwards.
To lock the On/Off switch 4, press the On/Off switch 4 down
at the front until it latches.
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.
To save energy, only switch the power tool on when using 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.
Speed preselection (GWS 11-125 CIE/GWS 14-125 CIE)
The required speed can be preselected with the thumbwheel 3 (also while running).
The data in the following table are recommended values.

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.
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 1400 C/
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 1400 C/
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 perfor-
mance.
