Dust/Chip Extraction

The dust from materials such as lead paint, some types of

wood, minerals and metal can be harmful to human health.

Touching or breathing in this dust can trigger allergic reac-

tions and/or cause respiratory illnesses in the user or in

people in the near vicinity.

Certain dusts, such as oak or beech dust, are classified as

carcinogenic, especially in conjunction with wood treatment

additives (chromate, wood preservative). Materials contain-

ing asbestos may only be machined by specialists.

– Use a dust extraction system that is suitable for the ma-

terial wherever possible.

– Provide good ventilation at the workplace.

– It is advisable to wear a P2 filter class breathing mask.

The regulations on the material being machined that apply in

the country of use must be observed.

uAvoid dust accumulation at the workplace. Dust can

easily ignite.

Operation

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

stop.

uPull the plug out of the socket before carrying out any

work on the power tool.

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.

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.

Working advice

Rough grinding

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

rough grinding with bonded abrasives.

uNever use cutting discs for rough grinding.

uWhen rough grinding, the protective guard for

cutting(10) or the protective guard for grinding(9)

with a fitted cover for cutting(11) can impact the

workpiece and lead to a loss of control.

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.

uThe protective guard for cutting(10) or the protective

guard for grinding(9) with a fitted cover for cutting(11)

must be used when using bonded discs which are ap-

proved for cutting and grinding.

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 (24) when working with the

rubber sanding pad (25).

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

ive guard.

See the graphics page for fitting instructions.

Screw on the round nut(27) and tighten it with the two-pin

spanner.

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 (24) 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.

The cup brush/conical brush/disc brush with M14 thread

must be screwed onto the grinding spindle until it rests

firmly against the grinding spindle flange at the end of the

grinding spindle thread. Tighten the cup brush/conical

brush/disc brush with an open-ended spanner.

To fasten the disc brush with a diameter of 22.22mm, at-

tach the mounting flange with O-ring(12) to the grinding

spindle(23), screw on the round nut(27) and tighten with

the two-pin spanner.

Cutting Metal

uFor cutting metal with bonded cutting discs or dia-

mond cutting discs, always use the protective guard

for cutting(10) or the protective guard for

grinding(9) with a fitted cover for cutting(11).

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.
