Dust extractor attachment and dust bag

(In concrete drilling operation)

With the dust extractor attachment and the dust bag installed
on this tool, you can do your work very cleanly without dust
scattered around in the work site.
CAUTION:
These two accessories can be used only for drilling
holes in concrete. Accordingly, do not use them in metal
or wood drilling operation.

Installing dust extractor attachment

Loosen the clamp screw of the side grip by turning it counter-
clockwise. Insert the coupling rod of the dust extractor
attachment through the coupling hole of the side grip until the
rod cannot be pushed in any further. And then tighten the
clamp screw clockwise to secure the dust extractor attach-
ment. The coupling rod can be inserted from either side A or
B.
NOTE:
At some angles of the side grip with the tool, the dust
extractor attachment cannot be installed on the tool
because of the interference between the attachment and
the tool.
