Selection of the Sanding Plate

Depending on the application, the machine can be equipped 
with sanding plates of different hardness:
– Soft sanding plate: Suitable for polishing and sensitive 

sanding (also for curved surfaces).

– Medium sanding plate: Suitable for all sanding applications 

and general-purpose use.

– Hard sanding plate: Suitable for high sanding capacity on 

flat surfaces.

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.

– As far as possible, use a dust extraction system suita-

ble for the material.

– 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 
materials to be worked.



Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.
