Adjusting the position of dust extractor
attachment
Loosen the clamp screw of the dust extractor attachment
by turning it counterclockwise.
And then align the tip of the bit with the top of the dust
extractor attachment.
Tighten the clamp screw by turning it clockwise to secure
the dust extractor attachment.
Depth adjustment
Loosen the screw of the stopper by turning it counter-
clockwise so that the stopper could slide on the depth
gauge of the dust extractor attachment. Slide the stopper
to the desired drilling depth of the gauge, and then
tighten the screw by turning it clockwise.
OPERATION
Drilling with dust extractor attachment
In drilling operation, hold the tool so that the top end of
the dust extractor attachment is always kept in complete
contact with the surface of concrete.
NOTE:
• Any space between them would result in a
considerable loss of dust extracting power.
Cleaning out dust bag
Remove the dust bag from the tool. Pull the fastener out
of the dust bag, and then remove dust or particles to
clean out the dust bag.
NOTE:
• Too much dust in the dust bag would result in a
considerable loss of dust extracting power.
Accordingly, clean out the dust bag from time to
time.
