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.

To remove the dust collection system, pull up the tool
while pressing the lock-off 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.

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.
