7. The device
7.1 Switching On/Off, Automatic
Select operating mode at switch (12):
Off = vacuum cleaner off
On = vacuum cleaner on (manual operation)
AUTO= switching On/Off- Automatic:
The vacuum cleaner is switched on or off
by means of a power tool connected to the
mains socket (5).
7.2 PressClean
See illustration G, page 2. To clean the filter (25)
using a strong air flow: Press the button (31) whilst
the suction is running (press down three times)
while keeping the suction opening shut (on the
suction hose or on the container).
7.3 Power socket (5) (only ASA 20-30 L/M/H PC
devices)
The power socket (5) is designed for
connection to a power tool only.
The total maximum permissible current
consumption (of vacuum cleaner and
connected unit) must not exceed the value I
table, page 3).
If the switch (12) is in the "AUTO" position, the
vacuum cleaner is switched on or off by means of a
power tool connected to the mains socket (5) .
7.4 Volume flow control display (10) (only for
devices ASA 20 M PC, ASA 20 M PC, ASA 30
M PC, ASA 30 H PC)
Lights up red when the required volume flow of 20
m/sec is not achieved.
The volume flow control display lights up and there
is an additional acoustic signal when the container
is full and/or if the suction hose is blocked.
For troubleshooting see chapter 10.2
8. Use
8.1 Dry Vacuuming
Vacuum using a dry filter, dry device and dry
accessories only. If the cartridge is damp, dust may
stick and form a crust.
Always use fleece filter bag (20) or PE disposal bag
(33) together with pleated filter (25).
8.2 Wet vacuuming
Never operate the machine without inserting
filter or special wet filter. The machine may be
destroyed and water may also escape.
Before carrying out any wet vacuuming, remove the
dry vacuumed material. This process will prevent
severe soiling and encrustation.
The appliance has a float system that enables it to
switch off the air flow when the maximum liquid level
is reached. When this happens, you will hear a
distinct change in the sound of the motor. Then
switch off the appliance and pull the plug from the
socket. Only vacuum liquids when the float (27) is
functioning properly (see chapter 10. maintenance).
After switching off, some water may run back out of
the hose.
Before emptying, first of all take the suction hose out
of the liquid.
If you are then going to dry vacuum, insert a dry
filter. If there is frequent switching between dry and
wet vacuuming, we recommend the use of a second
(replacement) filter. Allow the filter, container and
accessories to dry: otherwise dust may adhere to
damp components.
Before storage: leave humid filter and the inside of
the dust container to dry completely.
8.3 Transport
L class: Leave the hose on the machine to prevent
dust from accidentally being released.
M and H class: with the hose disconnected, close
the suction inlet with the plug. Insert the hose ends
into each other so that no dust can escape from the
hose.
Secure the suction hose or mains connection lead
(see
max
to the appliance using the accessory fixture (21)
and rubber (15).
The upper part (7) must be securely sealed to the
container (2) - check that the snap locks (13) are
closed.
The handle (6) is only permitted for
manual transport - not for attachment to
cranes or similar!
9. Cleaning
