When operating the machine with power from

mobile generators that do not have sufficient

reserve capacity or are not equipped with suit-

able voltage control with starting current ampli-

fication, loss of performance or untypical

behavior can occur upon switching on.

Please observe the suitability of the power gen-

erator being used, particularly with regard to

the mains voltage and frequency.

Switching On and Off

To

start

the power tool, push the On/Off switch

2

forwards.

To

lock

the On/Off switch

2

, press the On/Off

switch

2

down at the front until it latches.

To

switch off

the power tool, release the

On/Off switch

2

or, if it is locked, briefly push

down the back of the On/Off switch

2

and then

release it.

�

Check grinding tools before using. The

grinding tool must be mounted properly

and be able to move freely. Carry out a

test run for at least one minute with no

load. Do not use damaged, out-of-centre

or vibrating grinding tools.

Damaged

grinding tools can burst and cause injuries.

Working advice

��

��

Exercise caution when cutting slots in

structural walls; see Section “Informa-

tion on Structures ”.

��

��

Clamp the workpiece if it does not

remain stationary due to its own weight.

��

��

Do not strain the machine so heavily that

it comes to a standstill.

��

��

After heavily straining the power tool,

continue to run it at no-load for several

minutes to cool down the cutting/grind-

ing tool.

��

��

Grinding and cutting discs become very

hot while working; do not touch until

they have cooled.

��

��

Do not use the power tool with a cut-off

stand.

Rough grinding

��

��

Never use a cutting disc for roughing.

The best roughing results are achieved when

setting the machine at an angle of 30° to 40°.

Move the machine back and forth with moder-

ate pressure. In this manner, the workpiece will

not become too hot, does not discolour and no

grooves are formed.

Flap disc

With the flap disc (accessory), curved surfaces

and profiles can be worked.

Flap discs have a considerably higher service

life, lower noise levels and lower sanding tem-

peratures than conventional sanding sheets.

Cutting metal

��

��

For cutting metal, always work with the

protection guard for cutting 12.

When cutting, work with moderate feed,

adapted to the material being cut. Do not exert

pressure onto the cutting disc, tilt or oscillate

the machine.

Do not reduce the speed of running down cut-

ting discs by applying sideward pressure.
