Switching on/off

To start the power tool, push the on/off switch (4) forward.

To lock the on/off switch (4) in position, push the on/off

switch (4) forward and down until it clicks into place.

To switch off the power tool, release the on/off switch (4);

or, if the switch is locked, briefly push the on/off switch (4)

backward and down and then release it.

u Always check abrasive tools before using them. The

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

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 (4) to the off posi-

tion and then switch the power tool on again.

Speed preselection (GWX ... S)

You can preselect the required speed using the speed

preselection thumbwheel (5), even during operation. The in-

formation in the table below describes the recommended

values.

The values specified for speed levels are guide values.

u The rated speed of the accessory must be at least

equal to the maximum speed marked on the power

tool. Accessories running faster than their rated speed

can break and fly apart.

Working advice

u Pull the plug out of the socket before carrying out any

work on the power tool.

u Exercise caution when cutting slots in structural walls;

see the "Information on structures" section.

u Clamp the workpiece if it is not secure under its own

weight.

u Do not load the power tool so heavily that it comes to a

stop.

u If the power tool has been subjected to a heavy load,

continue to run it at no-load for several minutes to

cool down the accessory.

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

u Do not touch grinding and cutting discs until they have

cooled down. The discs can become very hot while work-

ing.

Rough grinding

u Never use cutting discs for rough grinding.

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

u Always use the protective guard for cutting (9) when

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.

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.

Cutting stone

u Provide sufficient dust extraction when cutting stone.

u Wear a dust mask.

u The power tool may be used only for dry cutting/grind-

ing.

For best results when cutting stone, use a diamond cutting

disc.

When using the extraction guard for cutting with a guide

block (18), the vacuum cleaner must be approved for vacu-

uming stone dust. Suitable vacuum cleaners are available

from Bosch.
