Dust Extraction/Dust Container
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
u Avoid dust accumulation at the workplace. Dust can
easily ignite.
u Use the dust box only when working on concrete and
stone. Wood chips and plastic chips can easily lead to
clogging.
u Warning: Danger of fire! Do not work on any metallic
materials with the dust container mounted. Hot metal
chips can ignite parts of the dust container.
Please observe the following instructions to optimise your
use of the dust container:
– Ensure that the dust container is placed flush against the
workpiece or wall. This also makes it easier to drill at a
right angle.
– When you reach the required drilling depth, pull the drill
bit out of the drill hole first and then switch off the impact
drill.
– The dust protection ring(15) can wear, especially when
working with large drill-bit diameters. Replace the dust
protection ring when worn/damaged.
