 Prevent dust accumulation at the workplace. Dust can
easily ignite.
 Use the dust box only when working on concrete and
stone. Wood chips and plastic chips can easily lead to
clogging.
 Warning: Danger of fire! Do not work on any metallic
materials with the dust box mounted. Hot metal chips
can ignite parts of the dust box.
Please observe the following instructions to optimise your use
of the dust box:
– Ensure that the dust box is placed flush against the work-
piece or wall. This also makes it easier to drill at a right an-
gle.
– After reaching the desired 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.
