(see chapter Emptying the dirt recepta-
cle ).
3. If necessary, clean the filter (see chapter
Dedusting the filter ) or change/
replace the filter (see chapter Replacing
the filter ).
Reading the minimum volumetric
flow
A pressure gauge showing the vacuum in-
side the device is mounted on the front of
the device. The filter must be cleaned when
the maximum vacuum (see table) is
reached (see chapter
Dedusting the filter ).
This value depends on the device perfor-
mance and the suction hose used. If the
vacuum is not significantly reduced by de-
dusting, the filter must be replaced (see
chapter
Replacing the filter ).
ATTENTION
Exceeding the maximum vacuum
Suction loss
If the specified value is exceeded, the air
speed in the suction hose drops below
20 m/s. Clean or replace the filter.
Dedusting the filter
The filter must be cleaned if the pressure
gauge shows the maximum vacuum (see
chapter
Reading the minimum volumetric
flow ).
