Dust can be hazardous to health. Always work with a
dust extractor. Always read applicable national regu
-
lations before extracting hazardous dust.
The power tool does not have its own extractor
unit. At the extractor connector (Fig 1.5), an
appropriate mobile dust extractor with an ex

traction hose diameter of 40mm should be con
-
nected. Use the dust extractor assembly kit as
demonstrated in Fig. 5.
