NOTICE:
Do not use the dust collection system
for core drilling or chiseling. The dust collection
system is intended for drilling only.
NOTICE:
Do not use the dust collection system
for metal or wood. The dust collection system is
intended for concrete only.
NOTICE:
Do not use the dust collection system
for drilling in wet concrete or use this system
in wet environment. Failure to do so may cause
malfunction.
NOTE: The dust collection system collects the gener-
ated dust at a considerable rate, but not all dust can
be collected.
Installing or removing the dust
collection system
NOTICE:
Before installing the dust collection
system, clean the joint parts of the tool and the
dust collection system.
Foreign matters on the joint parts may cause it diffi-
cult to install the dust collection system. Particularly
the foreign matters on the electrical interface may
cause malfunction.
If any dust remains on the air duct, the dust comes
into the tool and causes jam in the airflow or break-
age of the tool.
Hook the dust collection system on the tool, and then
insert the dust collection system all the way, until it locks
in place with a little double click.
After that, make sure that the dust collection system is
securely installed.

When removing the dust collection system, press the
lock-off button.

Adjusting the nozzle position of the
dust collection system
CAUTION:
Do not point the nozzle at yourself
or others when releasing the nozzle by pushing
the guide adjustment button.
Push in the guide while pushing the guide adjustment
button, and then release the guide adjustment button at
the desired position.

Adjusting the drilling depth of the
dust collection system
Slide the depth adjustment button to the desired posi-
tion while pushing it. The distance (A) is the drilling
depth.

Beating dust on the filter
CAUTION:
Do not turn the dial on the dust case
while the dust case is removed from the dust collec-
tion system. Doing so may cause dust inhalation.
CAUTION:
Always switch off the tool when
turning the dial on the dust case. Turning the dial
while the tool is running may result in the loss of
control of the tool.
By beating the dust on the filter inside the dust case,
you can keep the vacuum efficiency and also reduce
the number of times to dispose of the dust.
Turn the dial on the dust case three times after col-
lecting every 50,000 mm
vacuum performance declined.
NOTE: 50,000 mm
holes of ø10 mm and 14 mm depth (2 holes of ø65"
and 3/8" depth).

Disposing of dust
CAUTION:
Wear dust mask when disposing
of dust.
CAUTION:
Empty the dust case regularly
before the dust case becomes full. Failure to do so
may decrease the dust collection performance, and
then cause dust inhalation.
CAUTION:
Replace the filter with new one
after approximately 200 times of dust fulfillment
as a guide. A clogged filter decreases dust collection
performance, and then cause dust inhalation.
NOTICE:
When cleaning the filter, tap the case
of the filter gently by hand to remove dust. Do not
tap the filter directly; touch the filter with brush
or similar; or blow compressed air on the filter.
Doing so may damage the filter.
