damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Switch without locking mechanism (country-specific):
(GWS 24-180 P / GWS 24-230 P)
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).
Restart protection
(GWS 24-180 JZ / GWS 24-230 JZ)
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 24-180 JZ / GWS 24-230 JZ)
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.
Overload protection
(GWS 24-180 JZ / GWS 24-230 JZ)
When overloaded, the motor comes to a stop. Allow the
power tool to cool down unloaded at its maximum no-load
speed for approx. 5–10 seconds.
Emptying the dust box (see figure A)
(GWS 24-180 JZ / GWS 24-230 JZ)
Press both sides of the dust box (3) and remove the dust
box (3) from the power tool. Open the cover and empty the
dust box (3). Slide the dust box (3) back into the power tool
until it clicks into place.
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 use the power tool with a cut-off stand.

Bosch Power Tools
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Note: Remove the plug from the socket when not using the
tool. When the power tool is plugged in, mains voltage is
present and the tool consumes a small amount of electricity,
even if switched off.
Rough grinding
Never use cutting discs for rough grinding.
u
The best rough grinding results are achieved with a set angle
of 30° to 40°. Move the power tool back and forth with mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.
Flap Disc
With the flap disc (accessory), curved surfaces and profiles
can be worked. Flap discs have a considerably higher ser-
vice life, lower noise levels and lower sanding temperatures
than conventional sanding sheets.
Cutting Metal
Always use the protective guard for cutting (14) when
u
cutting bonded abrasives.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
Cutting stone
Provide sufficient dust extraction when cutting stone.
u
Wear a dust mask.
u
The power tool may be used only for dry cutting/grind-
u
ing.
For best results when cutting stone, use a diamond cutting
disc.
When using the extraction guard for cutting with a guide
block (22), the vacuum cleaner must be approved for vacu-
uming stone dust. Suitable vacuum cleaners are available
from Bosch.
English | 13
The power tool must always
work in an up-grinding mo-
tion. Otherwise, there is a
risk that it will be pushed
uncontrolled out of the cut.
For best results when cut-
ting profiles and rectangular
tubing, start at the smallest
cross section.
