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.

Soft start

The electronic soft start limits the torque when the power

tool is switched on and increases the service life of the mo-

tor.

Working Advice

uExercise caution when cutting slots in structural walls;

see the "Information on structural design" section.

uClamp the workpiece if it is not secure under its own

weight.

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

stop.

uIf 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.

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

uDo not touch grinding and cutting discs until they have

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

ing.

If the power tool becomes electrostatically charged, the

built-in electronics will switch the power tool off. Press the

on/off switch (4) again to restart the power tool.

Rough grinding

uNever 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

uAlways use the protective guard for cutting (10) 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 (see figure A)

uProvide sufficient dust extraction when cutting stone.

uWear a dust mask.

uThe 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 cutting

guide (20), the vacuum cleaner must be approved for vacu-

uming stone dust. Suitable vacuum cleaners are available

from Bosch.

Switch on the power tool

and position it with the

front part of the cutting

guide on the workpiece.

Move the power tool with a

moderate feed motion that

is suited to the material be-

ing machined.

When cutting especially

hard materials such as con-

crete with a high pebble content, the diamond cutting disc

can overheat and become damaged as a result. This is

clearly indicated by circular sparking, rotating with the dia-

mond cutting disc.

If this happens, stop cutting and allow the diamond cutting

disc to cool down by running the power tool for a short time

at maximum speed with no load.

If work is noticeably slower and with circular sparking, this

indicates that the diamond cutting disc that has become

dull. You can resharpen the disc by briefly cutting into abras-

ive material (e.g. lime-sand brick).

Information on structural design

Slots in load-bearing walls are subject to DIN 1053 part 1 or

country-specific regulations. These regulations must be ob-

served under all circumstances. Seek advice from the re-

sponsible structural engineer, architect or construction su-

pervisor before starting work.

Recommendations for optimal handling of the battery

Protect the battery against moisture and water.

Only store the battery only within a temperature range of -20

to 50 °C. Do not leave the battery in your car in the summer,

for example.

Occasionally clean the ventilation slots on the battery using a

soft brush that is clean and dry.
