Restarting Protection

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

The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation 
from a 13 ampere fuse.

Note: 

When the machine runs with full speed after switching 

on, the reduced starting current, the restarting protection 
and the kickback stop features have failed. The power tool 
must promptly be sent to an after-sales service agent for 
maintenance. For addresses, see Section „After-sales Service 
and Application Service“.

Constant Electronic Control

Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perfor-
mance.

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.

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.



Do not touch grinding and cutting discs before they 
have cooled down. 

The discs can become very hot while 

working.



Do not use the power tool with a cut-off stand.

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.

Cutting Metal



For cutting with bonded abrasives, always use the pro-
tection guard for cutting 14.

When cutting, work with moderate feed, adapted to the mate-
rial 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 ap-
plying sideward pressure.

The machine must al-
ways work in an up-
grinding motion. Other-
wise, the danger exists 
of it being pushed 

un-

controlled

 out of the 

cut.

When cutting profiles and square bar, it is best to start at the 
smallest cross section.

Cutting Stone



Provide for sufficient dust extraction when cutting 
stone.



Wear a dust respirator.



The machine may be used only for dry cutting/grinding.
