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.

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.
