Insert the vacuum hose from the vacuum
into the dust port of the dust extraction unit
(Fig. 9).
The Bosch vacuum hose comes with a
sleeve nozzle attached to a snap-in
connector (Fig. 9). The sleeve nozzle
provides the quickest, easiest connection of
the nozzle to the attachment. The snap-in
connector provides a more secured
connection.
To use the snap-in connector, remove the
rubber nozzle from the vacuum hos e. Press
the snap-in connector into the dust port until
you hear the click.
Dust port adaptors are also available to
connect the Bosch dust extraction
attachment to any common size vacuum
hose. See Boschtools.com for details.
Turn the vacuum on and place the tool /
attachment over the desired chiseling
location. Follow all tool safety and operating
instructions.
