Surface grinding with flap disc

uAlways use the protective guard for grinding(9) when

grinding with the flap disc.

The flap disc (accessory) enables you to machine curved

surfaces and profiles. Flap discs have a considerably longer

service life, lower noise levels and lower grinding temperat-

ures than conventional grinding discs.

Surface grinding with sanding disc

uAlways fit the hand guard (17) when working with the

rubber sanding pad (18).

Grinding with a sanding disc can be done without a protect-

ive guard.

See the graphics page for fitting instructions.

Cup brush/disc brush/conical brush

uAlways use the protective guard for grinding(9) when

brushing with disc brushes. Brushing with cup

brushes/conical brushes can be performed without

the protective guard.

uAlways fit the hand guard (17) when working with the

cup brush or conical brush.

uThe wires of the disc brush can get caught on the pro-

tective guard and break, if the maximum permitted di-

mensions of the disc brushes are exceeded.

See the graphics page for fitting instructions.

Cutting Metal

uFor cutting metal with bonded cutting discs or dia-

mond cutting discs, always use the protective guard

for cutting(11) or the protective guard for

grinding(9) with a fitted cover for cutting(13).

uWhen using the protective guard for grinding(9) for

cutting work with bonded cutting discs, there is an in-

creased risk of being exposed to sparks, particles and

disc fragments if the disc breaks.

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

uFor cutting stone with bonded cutting discs or dia-

mond cutting discs for concrete/stone, always use the

extraction guard for cutting with a cutting guide(25)

or the protective guard for cutting(11) or the protect-

ive guard for grinding (9) with a fitted cover for

cutting(13).

uProvide sufficient dust extraction when cutting stone.

uWear a dust mask.

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

ing.

uWhen using the protective guard for cutting(11) , the

protective guard for grinding(9) or the protective

guard for grinding(9) with a fitted cover for

cutting(13) for cutting and grinding applications in

concrete or masonry, there is an increased dust load

and an increased risk of losing control of the power

tool, which can lead to kickback.

For cutting stone, it is best to use a diamond cutting disc.

When using the extraction guard for cutting with a cutting

guide(25), the dust extractor must be approved for extract-

ing stone dust. Suitable dust extractors 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 has become blunt.

You can resharpen the disc by briefly cutting into abrasive

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

Cutting other materials

uFor cutting materials such as plastic, composite ma-

terials, etc. with bonded cutting discs or Carbide Multi

Wheel cutting discs, always use the protective guard

for cutting(11) or the protective guard for

grinding(9) with a fitted cover for cutting (13). You

can achieve improved dust extraction by using the ex-

traction guard with a cutting guide(25).

Working with Diamond Annular Cutters

uOnly use dry diamond annular cutters.

uAlways fit the hand guard (17) when working with dia-

mond annular cutters.

Do not place the diamond annular cutter parallel to the work-

piece. Plunge it into the workpiece at an angle and in a circu-

lar motion. This will allow you to achieve optimal cooling and

ensure a longer tool life for the diamond annular cutter.
