Performing the vacuuming process
1. Regularly check the filling level in the dirt
receptacle, since the device does not
switch off automatically.
Note
The device is equipped with a mechanical
monitoring unit. This monitoring unit inter-
rupts the airflow when the inert liquid falls
below the minimum filling level. Refill with
inert liquid to continue the vacuuming pro-
cess (see chapter Fill the dirt receptacle
with inert liquid).
2. Make sure that no more than 8 litres of
material are sucked in during vacuum-
ing.
3. If necessary, empty the dirt receptacle
(see chapter Emptying the dirt recepta-
cle).
4. If necessary, replace the main filter (see
chapter Replacing the main filter).
Note
If the dirt receptacle is filled with an inert liq-
uid, moist air may flow through the main fil-
ter during suction and soak it. Check the
main filter for moisture after the vacuuming
process. If necessary, let the main filter dry
or replace it (see chapter Replacing the
main filter).
Reading the minimum volumetric
A pressure gauge showing the vacuum in-
side the device is mounted on the front of
the device. The main filter must be cleaned
when the maximum vacuum (see table) is
reached, see chapter Replacing the main
filter). This value depends on the device
performance and the suction hose used. If
the vacuum is not significantly reduced by
replacing the filter, there must be another
problem (see chapter Troubleshooting
guide).
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. Replace the filter.

Switching off the device
1. Switch off the device via the suction tur-
bine power switches.
2. Pull out the mains plug.
3. Disconnect the earth terminal from the
external equipotential bonding.
Each time after use
1. Remove the accessories.
2. Close the suction connection (see chap-
ter Closing the suction connection).
3. Remove the accessories and, if neces-
sary, flush with water and allow to dry.
4. Empty the dirt receptacle (see chapter
Emptying the dirt receptacle).
5. Vacuum the inside and outside of the de-
vice and clean with a moist cloth.
Emptying the dirt receptacle
The dirt receptacle must be emptied if nec-
essary and after each use.
The inlet opening or the suction hose are
closed.
Regularly check the filling level in the dirt
receptacle, since the device does not
switch off automatically.
1. Switch off the device.
2. Secure the device with the parking
brakes.
