Rotating the Machine Head



Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport 
and storage, remove the battery from the power tool. 

There is danger of injury when unintentionally actuating 
the On/Off switch.

The machine head can be 
rotated with respect to 
the machine housing in 
90 ° steps. In this man-
ner, the On/Off switch 
can be brought into a 
more convenient position 
for special working situa-
tions, e.g. for left-handed 
persons.

Completely unscrew the 
four screws. Rotate the 

machine head carefully, 

without removing it from the hous-

ing,

 to the new position. Screw in and tighten the four screws 

again.

Dust/Chip Extraction



Dusts from materials such as lead-containing coatings, 
some wood types, minerals and metal can be harmful to 
one’s health. Touching or breathing-in the dusts can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered 
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials 
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the mate-
rials to be worked.



Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

Operation

Starting Operation

Inserting the battery

Insert the charged battery 

5

 from the front into the base of the 

power tool until the battery is securely locked.

Switching On and Off

To 

start

 the power tool, push the On/Off switch 

3

 forwards.

To 

lock

 the On/Off switch 

3

, press the On/Off switch 

3

 down 

at the front until it latches.

To 

switch off

 the power tool, release the On/Off switch 

3

 or, 

if it is locked, briefly push down the back of the On/Off switch 

3

 and then release it.

To save energy, only switch the power tool on when using 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 grind-
ing tools. 

Damaged grinding tools can burst and cause in-

juries.

Working Advice



Exercise caution when cutting slots in structural walls; 
see Section “Information 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 acces-
sory.



Do not touch grinding and cutting discs before they 
have cooled down. 

The discs can become very hot while 

working.



Do not use the power tool with a cut-off stand.

When the power tool is electrostatically charged, the built-in 
electronic control switches it off. To restart the power tool, 
press the On/Off switch 

3

 again.

Rough Grinding



Never use a cutting disc for roughing.

The best roughing results are achieved when setting the ma-
chine at an angle of 30 ° to 40 °. Move the machine back and 
forth with moderate 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 temperatures than conventional 
sanding sheets.

Cutting Metal



For cutting with bonded abrasives, always use the pro-
tection guard for cutting 16.

When cutting, work with moderate feed, adapted to the mate-
rial being cut. Do not exert pressure onto the cutting disc, tilt 
or oscillate the machine.

Do not reduce the speed of running down cutting discs by ap-
plying sideward pressure.
