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 kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically.
Speed preselection
GWS 750 S
You can preselect the required speed using the speed preselection thumbwheel (22), even during operation. The information
in the table below describes the recommended values.
Material Application
Metal Removing paint
Metal Brushing, removing rust
Metal, stone Grinding
Metal Rough grinding
Metal Cutting
The values specified for speed levels are guide values.
The rated speed of the accessory must be at least
u
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed
can break and fly apart.
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.
u
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Bosch Power Tools
To restart the tool, set the On/Off switch (2) to the "off" po-
sition and then switch the power tool on again.
Restart protection
GWS 700 / GWS 710(115) / GWS 750 / GWS 750-100 I /
GWS 750 S
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 750-100 I / GWS 750 S
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.

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.
