DUST COLLECTION
SYSTEM
Optional accessory
The dust collection system is designed to collect dusts
effectively when the concrete drilling operation.
► Fig.25: 1. Dust collection system
CAUTION:
The dust collection system is
intended for drilling in concrete only. Do not use
the dust collection system for drilling in metal or
wood.
CAUTION:
When using the tool with the dust
collection system, be sure to attach the filter
to the dust collection system to prevent dust
inhalation.
CAUTION:
Before using the dust collection
system, check that the filter is not damaged and
the inner pipe is free of dust and foreign matter.
Failure to do so may cause dust inhalation.
CAUTION:
The dust collection system col-
lects the generated dust at a considerable rate,
but not all dust can be collected.
NOTICE:
Do not use the dust collection system
for core drilling or chiseling.
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.

Installing or removing

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 difficult to install the dust collection
system. If any dust remains on the air duct, the dust
comes into the tool and causes jam in the airflow or
breakage of the tool.
To install the dust collection system, insert the tool
completely into the dust collection system until the tool
is locked in place with a little click.
► Fig.26
To remove the dust collection system, pull up the tool
while pressing the lock-off button.

Adjusting nozzle position
CAUTION:
Do not point the nozzle at yourself
or others when releasing the nozzle by pushing
the guide adjustment button.
Slide in and out the nozzle guide while pressing the
guide adjustment button, and then release the button
at an exact position where the tip of the drill bit sits just
behind the front surface of the nozzle.

Adjusting drilling depths
Drilling depths can be adjusted by changing the lengths
between the depth adjustment button and the support
arm for nozzle guide. Press and hold the depth adjust-
ment button and slide it to your desired position.

Beating dust on the filter
CAUTION:
Do not turn the dial on the dust
case while the dust case is removed from the
dust collection 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
10 holes of ø10 mm and 65 mm depth.
