When the end of the nozzle and the tip of the drill bit are
aligned, the distance that the nozzle can move is drilling
depth. (Fig. 9)

NOTE
○ The dust extractor system is only to be used when
drilling concrete.
Do not use it while drilling metal or wood.
○ Do not use the dust extractor system with wet concrete
or in a wet environment. Doing so may result in a
malfunction.
(1) Grasp the nozzle with your hand and pull it back slightly,
and align the tip of the drill bit with the spot to be drilled.

(2) Release the nozzle and allow it to make fi rm contact with
the surface of the concrete. (Fig. 11)

NOTE
If the nozzle is raised off the surface, the dust extraction
performance declines.
(3) With the end of the nozzle still in fi rm contact with the
surface of the concrete, proceed with drilling. (Fig. 12)
5. Emptying the dust
If too much dust is collected in the dust box, the dust
extraction performance declines.
Additionally, if the dust box is full, dust may leak out of
the dust extractor system.
Inspect the dust extractor system regularly, and dispose
of the dust before it becomes full.
WARNING
When emptying the dust, in order to prevent an unlikely
accident, be sure to turn off the tool's switch and remove
the rechargeable battery from the tool body.
