7. The Appliance
7.1
Switching On/Off, Automatic, vibrator
Select operating mode at switch (1):
0= Vacuum cleaner off
I = Vacuum cleaner on (manual operation)
A=Automatic On/Off switch:
The vacuum cleaner is switched on or off by
means of a power tool connected to the
mains socket (3).
R A= Automatic On/Off switch and
Automatic vibrator switch
• If the switch (1) is turned to position R A, the
electromagnetic vibrator switches on. Dust is
then shaken off the filter. The vibrator
switches off automatically after approx. 10 s.
• In switch position R A, the vacuum cleaner
is switched on or off by means of a power tool
connected to the mains socket (3).
• In switch position R A, the electronic system
checks the air flow during work. If the flow is
too low due to a contaminated filter, the
"Filter control" lamp lights up (2). During the
next work break of the connected power tool,
the electronics system switches the vibrator
off for approx. 10 s.
ASR 50 M SC:
• If an average air flow rate of 20 m/s in the
hose system with a diameter of 35 mm is
undershot, the volume flow control display (2)
flashes to indicate that the paper filter bag
has to be changed or the vibrator has to be
actuated.
7.2
Power socket (3)
The power socket (3) is designed for connec-
tion 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 2).
Caution! Ensure that the power tool is
switched off when plugging it in. Regardless of
the switch position, the plug socket is always live
when the mains plug is plugged in.
If the switch is (1) in the "0" position, you can use
the plug socket as an extension lead (e.g. for a light
fitting).
If the switch (1) is in the "RA" position, the vacuum
cleaner is switched on or off by means of a power
tool connected to the mains socket (3).
7.3
Volume flow control display
The volume flow control display lights up when the
container is full and/or if the suction hose is blocked.
(2). In the case of ASR 50 M SC, an acoustic signal is
also issued.
7.4
Rotary switch for setting the suction hose
diameter (ASR 50 M SC only)
Adjust the rotary switch (4) to the hose diameter of
the suction hose fitted.
18
The volume flow is being monitored if switch (1) is at
the "RA" or "I" position.
If the volume flow falls below a set value, the filter
cassettes (17) are automatically vibrated (without
any reduction in suction power). If the value remains
too low, the volume flow control display lights up and,
in switch position "RA" an acoustic signal is also
sounded to indicate that the container must be
emptied, or that the paper filter bag (7) / fleece filter
bag (6) or the PE filter bag (5) must be replaced.
dia. 35 mm => 70 m³/h
dia. 27 mm => 41 m³/h
dia. 19 mm => 20 m³/h
Note: If the suction hose diameter is 19 mm or less,
and if the flow conditions in the suction hose are
unfavourable, the volume flow control display (2) may
occasionally light up and the acoustic signal may
sound, even though the paper filter bag/fleece filter
bag does not yet need to be emptied. In this case,
lay out the hose straight and clean it.
Note: If you need to turn the rotary switch to a lower
value because of a machine generating dust (e.g.
small diameter of suction canal in the machine
generating dust, compared to large suction hose
diameter) (4), there is no guarantee that dust will be
conveyed adequately in the suction hose. The
suction hose must be removed from the machine
generating dust after every operating sequence, so
it can be vacuumed clear.
8. Use
8.1
Dry Vacuuming
Vacuum using a dry filter, dry appliance and dry
accessories only. If the cartridge is damp, dust may
stick and form a crust.
Always use filter cassettes when using paper filter
bags (7), fleece filter bags (6) or PE filter bags (5)
(17).
(see
max
8.2
Wet vacuuming
Never operate the machine without inserting a
filter cassette first (17) The machine may be
destroyed and water may also escape.
Vacuum without a paper filter (7) bag. You can use
either fleece filter bags (6) or PE filter bags (5). The
filter cartridges (17) are suitable for wet vacuuming.
Before carrying out any wet vacuuming, remove the
dry vacuumed material. This process will prevent
severe soiling and encrustation.
The integrated water sensor switches off the motor
when the container is full. Empty the appliance. If
the appliance is not switched off, the restart protec-
tion device remains effective. The appliance is not
operable again until it has been switched off and
switched back on again.
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
