► 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.
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.
Installation
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.
Hang the hooks of the dust collection system on the
pockets at the bottom front of the tool. Lift the nozzle
up to secure the dust collection system in place with a
click, so the air duct of the tool becomes covered with
the suction air outlet of the dust collection system.
