Depth adjustment
Loosen the screw of the stopper by turning it counterclock-
wise 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.
Drilling without dust extractor attachment
This tool can be also used as a standard rotary hammer
without the dust extractor attachment and the dust bag.
Before drilling operation without the dust extractor attach-
ment and the dust bag, plug the hose port with the cap pro-
vided. The cap reduces the exhaust air from the dust exhaust
port for your comfortable operation.
