3.3 AutoClean
N
The "AC" machine is equipped with an automatic fil-
ter cleaning system, AutoClean. A frequent cleaning
S
cycle will automatically run during operation to en-
sure that suction performance is always at its best.
DK
If suction performance decreases or in extensive
dust applications a manually filter cleaning operation
SF
is recommended:
1. Switch off the machine.
E
2. Close the nozzles or suction hose opening with
the palm of your hand.
P
3. Turn the switch to position „I" and let the ma-
chine operate at full speed for approx. 10 sec-
GR
onds with the suction hose opening closed.
If suction power is still reduced take out the filter and
TR
clean mechanically or replace filter.
For certain applications, like wet pick up, it is recom-
SLO
mended to turn off the automatic filter cleaning sys-
tem. For details see chapter 3.1.

The machine is equipped with a system to monitor
air velocity and Dust Class H filter condition
picking up dust with occupational exposure limit val-

1. When the motor is running, hold the suction
hose shut to reduce the volume flow. The LED
indicator on front panel will light after approx. 1
BG
second. The acoustic warning sounds after some
additional seconds.
RUS
2. Set the diameter setting to the actual hose size.
When LED indicator lights, air velocity is
EST
below 20 m/s.check if container or filter bag
is full.

3.5 Antistatic connection
CAUTION
The machine is equipped with an antistatic system to discharge any static electricity that
may develop during dust pick-up.
The antistatic system is placed in front part of the
motor top and creates an earth ground connection to
the inlet fitting of the container.
For proper function the use of an electrical conduc-
tive or antistatic suction hose is recommended.
1. When inserting the optional disposal bag make
sure the antistatic connection is kept.
3.6 Cooling air filter
To protect the electronics and motor, the machine is
equipped with a cooling air diffusor. Clean the cool-
ing air diffusor regularly.
For areas with a high concentration of fine dust in
the surrounding air it is recommended to equip the
machine with an optional cooling air filter cartridge to
prevent dust from settling inside the air channels and
motor. Contact your local sales representative.
CAUTION
If cooling air filter is clogged by dust the over-
load protection switch in the motor can be acti-
vated.
1. In such case switch off the machine, clean cool-
ing air filter and allow machine to cool for approx.
5 minutes.
3.7 Wet pick-up
CAUTION
The machine is equipped with a water level
limit system which shuts off the machine when
the maximum liquid level is reached.
1. When this occurs, switch off the machine.
2. Disconnect the machine from the socket and
empty the container.
3. Never pick up liquids without the water level limit
system and filter in place.
4. Do not pick up flammable liquids.
5. Before liquids are picked up, always remove the
filter bag/wastebag and check that the water
level limit works properly.
6. If foam appears, stop work immediately and
emty the tank.
7. Clean the water level limiting device regularly
and check for signs of damage.
Before emptying the container, unplug the machine.
Disconnect the hose from the inlet by pulling out the
