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.
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.
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.
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.

Switching on/off
To start the power tool, push the on/off switch (2) forward
and then press it down.
To lock the on/off switch (2) in position, push the on/off
switch (2) further forward.
To switch off the power tool, release the on/off switch (2);
or, if the switch is locked, briefly press the on/off switch (2)
and then release it.
Switch without locking mechanism (country-specific):
To start the power tool, push the on/off switch (2) forward
and then press it down.
To switch off the power tool, release the on/off switch (2).
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.
Restart protection
(GWS 20-230 J / 22-180 J / 22-230 J)
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
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 20-230 J / 22-180 J / 22-230 J)
The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the starting current limit-
ation and restarting protection mechanisms have failed. The
power tool must be sent to the after-sales service immedi-
ately; see the "After-Sales Service and Application Service"
section for addresses.
Working advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Exercise caution when cutting slots in structural walls;
u
see the "Information on structural design" section.
Clamp the workpiece if it is not secure under its own
u
weight.
Do not load the power tool so heavily that it comes to a
u
stop.
If the power tool has been subjected to a heavy load,
u
continue to run it at no-load for several minutes to
cool down the accessory.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Do not use the power tool with a cut-off stand.
