Approved Grinding Tools

All grinding tools mentioned in these operating 
instructions can be used.
The permissible speed [min

-1

] or the circumfer-

ential speed [m/s] of the grinding tools used 
must at least match the values given in the table.
Therefore, observe the permissible 

rotation-

al/circumferential speed

 on the label of the 

grinding tool.

Dust/Chip Extraction

f

Dusts from materials such as lead-containing 
coatings, some wood types, minerals and 
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are 
considered as carcinogenic, especially in 
connection with wood-treatment additives 
(chromate, wood preservative). Materials 
containing asbestos may only be worked by 
specialists.
– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your 
country for the materials to be worked.

f

Prevent dust accumulation at the work-
place. 

Dusts can easily ignite.

Operation

Starting Operation

f

Observe correct mains voltage! The voltage 
of the power source must agree with the 
voltage specified on the nameplate of the 
machine. Power tools marked with 230 V 
can also be operated with 220 V.

Switching On and Off

To 

start

 the power tool, press the On/Off switch 

5 forward and then down.
To 

lock-on

 the pressed On/Off switch 5, push 

the On/Off switch 5 further forward.
To 

switch off

 the power tool, release the On/Off 

switch 5, or when it is locked, briefly press the 
On/Off switch 5 and then release it.

f

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.

Speed preselection

The required speed can be preselected with the 
thumbwheel 4 (also while running).
The required speed depends on the material 
and the working conditions and can be deter-
mined through practical testing.

Constant Electronic Control

Constant electronic control holds the speed 
constant at no-load and under load, and ensures 
uniform working performance.
