Choosing the sanding sheet
Different sanding sheets are available, depending on the material you are working with
and the required surface removal rate:
Can be used to work on all materials including wood,
paint, filler, varnish, hard and softwood as well as chip-
board and metal.
For pre-sanding, e.g. of rough and uneven beams and
boards
For surface sanding and levelling of slight irregularities
For finishing and fine sanding of hard woods
For any finishing work, such as polishing (metal and stone in particular), use fleece/pol-
ishing felt.
Different types of fleece and polishing felts should be used depending on the surface fin-
ish required on the workpiece.
Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or bystanders.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in con-
nection with wood-treatment additives (chromate, wood preservative). Materials con-
taining 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 materials to be worked.
Avoid dust accumulation at the workplace. Dust can easily ignite.
