Suction system
The suction fan is connected via a belt coupling to the diesel
engine, and is operated with compressed air. Under the
ALARM page in the display, check that “Air pressure VAC
main switch” is inactive (green symbol). To activate vacuum
cleaning, set the knob in the ON position.
Operation
If the suction system is to be effective, it is necessary for
the cyclones to be emptied at regular intervals. The suction
system is designed with two parallel routes in order that they
can be emptied independently of each other, which means
that you are never without suction capacity. This takes place
automatically as long as the suction system has been acti-
vated.
In order to empty one side manually, press either LEFT or
RIGHT by EMPTY VAC under the SERVICE page. It is not
possible to empty both sides simultaneously.
In order to replace vacuum cleaner bag: Press LEFT or
RIGHT under “EMPTY VAC” in the SERVICE menu. Wait
until the indicator is green (can take up to 30 seconds). Re-
place bag.
When suction is to be activated again, press the same but-
ton again.
The emptying interval can be regulated by the SOFT
GRINDING button indicating red or green in the SER-
VICE menu, where green indication in the event of HEAVY
GRINDING means that emptying takes place at short inter-
vals.
Pay attention to the level to which the Longopac bags below
the cyclones are lled, so that they are replaced at the right
time.
