power tool, the electronics system switches
the vibrator off for approx. 10 s.
ASR 25 M SC, 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 fleece 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
connection to a power tool only. The total
maximum permissible current consumption
(of vacuum cleaner and
connected unit) must not exceed the value I
max
(see 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 25 M SC, ASR 50 M SC, an acoustic
signal is also issued.
7.4 Rotary switch for setting the suction hose
diameter (ASR 25 M SC, ASR 50 M SC only)
Adjust the rotary switch (4) to the hose diameter
of the suction hose fitted.
The volume flow is being monitored if switch (1) is
at the "RA", „A“ or "I" position.
If the volume flow falls below a set value, the filter
cassettes are automatically vibrated in the work
breaks in position RA. 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 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 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 fleece filter
bags (6) or PE filter bags (5) (16).
8.2 Wet vacuuming
Never operate the machine without
inserting a filter cassette first (16) The
machine may be destroyed and water may also
escape.
Vacuum without a paper filter (6) bag. You can
use either fleece filter bags (6) or PE filter bags
(5). The filter cartridges (16) 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 protection 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 (replacement) filter. Allow the filter,
container and accessories to dry: otherwise dust
may adhere to damp components.
8.3 Special instructions for ASR 25 M SC,
ASR 50 SC
Use as industrial vacuum cleaner (IS): Turn
switch (1) to the "I" position.
Adjust the rotary switch (4) to the hose diameter
of the suction hose fitted.
