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 reac-
tions 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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Always use dust extraction.
– 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.
The dust/chip extraction can be blocked by
dust, chips or workpiece fragments.
– Switch the machine off and pull the mains
plug from the socket outlet.
– Wait until the saw blade has come to a com-
plete stop.
– Determine the cause of the blockage and cor-
rect it.
Integrated Dust Extraction (see figure C)
– Mount the dust bag 19 onto the sawdust
ejector 22.
During sawing, the dust bag must never come in-
to contact with the movable machine parts.
Always empty the dust bag in good time.

When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
