Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [rpm] or the circumferential speed
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Dust/chip extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Start-up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Hold the tool by the insulated gripping surfaces and
u
auxiliary handle only. The application tool could come

into contact with hidden wiring or its own cord. Con-
tact with live wires may make metal parts of the tool live,
posing a risk of electric shock.
When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
Please check the suitability of the power generator you are
using, particularly with regard to the mains voltage and fre-
quency.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching on/off
To start the power tool, push the on/off switch (2) forward.
To lock the on/off switch (2) in position, push the on/off
switch (2) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (2);
or, if the switch is locked, briefly push the on/off switch (2)
backward and down and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Kickback stop (GWS 750-100 I)
If there is a sudden drop in the speed of the
power tool, e.g. jamming in a separating cut,
the power supply to the motor will be interrup-
ted electronically.
To restart the tool, set the on/off switch (2) to the "off" posi-
tion and then switch the power tool on again.
Restart protection (GWS 750-100 S/GWS 750-115 S/
GWS 750-125 S/GWS 750-100 I)
The restart protection prevents an uncontrolled start-up of
the power tool after an interruption in the power supply.
To restart the tool, set the on/off switch (2) to the "off" posi-
tion and then switch the power tool on again.
Starting current limitation (GWS 750-100 S/
GWS 750-115 S/GWS 750-125 S/GWS 750-100 I)
The electronic starting current limitation restricts the power
consumption when the power tool is switched on and en-
ables operation with a 16 A fuse.
Speed preselection (GWS 750-100 S/GWS 750-115 S/
GWS 750-125 S)
You can preselect the required speed using the speed
preselection thumbwheel (3), even during operation. The in-
formation in the table below describes the recommended
values.
