■ Hold the power tool only by the insulated

gripping surfaces, when performing an op-

eration where the cutting tool may run into

hidden wiring or its own cord.

Contact with a “live” wire will make exposed

metal parts of the tool “live” and shock the op-

erator.

■ Use appropriate detectors to determine if

utility lines are hidden in the work area or

call the local utility company for assist-

ance.

Contact with electric lines can lead to fire and

electric shock. Damaging a gas line can lead

to explosion. Penetrating a water line causes

property damage or may cause an electric

shock.

■ For work with grinding or cutting discs, the pro-

tection guard 6 must be mounted. For work

with the rubber sanding plate 20 or with the

cup brush 23/disc brush/flap disc, the hand

guard 18 (accessory) is to be mounted.

■ Use dust extraction when working with stone.

The vacuum cleaner must be approved for ma-

sonry dust. When cutting stone, use the cutting

guide.

■ Do not work with materials containing asbes-

tos.

■ Use only grinding tools with a permissible

speed at least as high as the no-load speed of

the machine.

■ Check grinding tools before use. The grinding

tool must be properly mounted and turn freely.

Perform a test run for at least 30 seconds with-

out load. Do not use damaged, out-of-round or

vibrating grinding tools.

■ Protect the grinding tool from impact, shock

and grease.

■ Apply the machine to the workpiece only when

switched on.

■ Keep hands away from rotating grinding tools.

■ Pay attention to the direction of rotation. Al-

ways hold the machine so that sparks and

grinding dust fly away from the body.

■ When grinding metal, flying sparks are pro-

duced. Take care that no persons are endan-

gered. Due to danger of fire, no combustible

materials should be located in the vicinity

(spark flight zone).

■ Be careful when cutting grooves, e. g. in struc-

tural walls: See Information on Structures.

■ Blocking the cutting disc leads to jerking reac-

tion forces on the machine. In this case switch

off the machine immediately.

■ Pay attention to the dimensions of the grinding

disc. The mounting hole diameter must fit the

mounting flange 9 without play. Do not use re-

ducers or adapters.

■ Never use cutting discs for rough grinding. Do

not exert any lateral pressure on the cutting

discs.

■ Observe the manufacturer’s instructions for

mounting and using grinding tools.

■ Caution! The grinding tool runs on after the

machine is switched off.

■ Do not clamp the machine in a vice.

■ Never allow children to use the machine.

■ Bosch is only able to ensure perfect operation

of the machine if the original accessories in-

tended for it are used.

The machine is intended for cutting, roughing and

brushing metal and stone materials without using

water. For cutting stone, a cutting guide is re-

quired.

Slots in structural walls are subject to the Stand-

ard DIN 1053, Part 1 or country-specific regula-

tions.

These regulations are to be observed under all

circumstances. Before beginning work, consult

the responsible structural engineer, architects or

the construction supervisor.
