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

Start-Up

uPay attention to the mains voltage. The voltage of the

power source must match the voltage specified on the

rating plate of the power tool. Power tools marked

with 230V can also be operated with 220V.

uProducts that are only sold in AUS and NZ: Use a resid-

ual current device (RCD) with a nominal residual current

of 30 mA or less.

When operating the power tool using a mobile generator that

does not have sufficient reserve capacity or an adequate

voltage control system with inrush current boost converter,

loss of performance or atypical behaviour may occur upon

switch-on.

Please check the suitability of the power generator you are

using, particularly with regard to the mains voltage and fre-

quency.

uHold the tool by the insulated gripping surfaces and

auxiliary handle only. The application tool could come

into contact with hidden wiring or its own cord. Con-

tact with live wires may make metal parts of the tool live,

posing a risk of electric shock.

Switching on/off

To start the power tool, push the on/off switch (4) forward.

To lock the on/off switch (4) in position, push the on/off

switch (4) forward and down until it clicks into place.

To switch off the power tool, release the on/off switch (4);

or, if the switch is locked, briefly push the on/off switch (4)

backward and down and then release it.

uAlways 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.

Working advice

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.

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.

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 (8) 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

uProvide sufficient dust extraction when cutting stone.

uWear a dust mask.

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

ing.
