Vacuuming the Dust Resulting from
Running Power Tools
(ENT operation mode with remote automatic
switching)
When the outgoing air is circulated (re-
maining in the work area), a sufficient rate
of air-change (L) in the room must be
given. Observe the respective TRGS 560
regulations. Measured with a Ø 35 mm
vacuum hose at 5 m length, the air flow
amounts to 39 l/s and the maximum vac-
uum to 225 mbar.
Wear a dust protection mask.
In this operation mode the machine can only be
operated in conjunction with a power tool (e. g.
circular saw).
The vacuum cleaner is switched on automati-
cally by the power tool connected to the
socket 7.
The socket 7 of the vacuum cleaner must be
used only for the purposes specified in the oper-
ating instructions.
For connecting the power tools, various hose
systems are available as accessories.
Set the airflow regulator 5 to the suction hose di-
ameter (19 mm or 35 mm) being used.
To ensure adequate dust transport at the vacu-
uming location, the airflow should not fall below
the minimum required amount for the connected
power tool.

Set the mode selector switch 6 to the operation
with remote automatic switching symbol.
In this setting, the volume flow is electronically
controlled according to the adjustment of the air-
flow regulator 5.
With the correct chosen setting, sufficient dust
transport is guaranteed.
To start the operation of the vac, switch on the
power tool connected to the socket outlet 7. The
vacuum cleaner starts automatically. When the
alarm sounds and the warning lamp 4 flashes,
switch the power tool off (the vac automatically
switches off approx. 6 seconds later) and check
as described in the section "Malfunctions".

Reduced Starting Current
(ENT operation mode with remote automatic
switching)
Due to the soft starting of the machine, a starting
current of 13 A is not exceeded.
Electromagnetic filter cleaning
The machine is equipped with an electromag-
netic filter cleaning system, which removes dust
adhering to the folded filter 18.
The filter cleaning system must be actuated lat-
est when the vacuuming performance is no
longer sufficient.
Set the mode selector switch 6 to the symbol
electromagnetic filter cleaning. A possibly
connected power tool must be switched off.
The machine vibrates for approx. 10 seconds
and switches off automatically.
Wait shortly before restarting the vacuuming op-
eration so that the dust can settle in the con-
tainer.
The filter cleaning frequency depends on the
type and amount of dust.
With regular usage, the maximum vacuuming
performance is maintained longer.

The dust bag 17 must be removed before wet
vacuuming.
Empty the container before wet vacuuming.
The machine is equipped with level sensors 20.
The machine switches off when the maximum
filling height is reached. Set the switch to off.
Before opening and emptying, always pull the
plug from the socket outlet.
After vacuuming, remove the folded filter 18 and
allow it to dry thoroughly, in order to avoid mil-
dew. Also remove the vacuum top 3 and allow it
to dry, too.
