, i.e. the machine can be used as an extension 

cord.
In position             the machine can be switched on 
and off by the power tool connected. Dirt is picked 
up from the source of dust immediately. To comply 
with regulations, only approved dust producing tools 
should be connected.

The maximum power consumption of the connected 
electrical appliance is stated in section “Specifica-
tions”.

Before turning the switch to position           ensure 
that the tool connected to the appliance socket is 
switched off.

3.3 Push&Clean

*)

The “PC” machine is equipped with a semi automatic 
filter cleaning system, Push&Clean. The filter clean-
ing system must be actuated latest when the suction 
performance is no longer sufficient. Regular use of 
the filter cleaning feature maintains suction perfor-
mance and increases the lifetime of the filter. For 
instruction see quick reference guide.

3.4 InfiniClean

*)

The “IC” machine is equipped with an automatic filter 
cleaning system, InfiniClean. A frequent cleaning cy-
cle will automatically run during operation to ensure 
that suction performance is always at its best.

If suction performance decreases or in extensive 
dust applications a manually filter cleaning operation 
is recommended:
• 

Switch off the machine

• 

Close the nozzles or suction hose opening with 
the palm of your hand.

• 

Turn the switch to position „I“ and let the ma-
chine operate at full speed for approx. 10 sec-
onds with the suction hose opening closed.

If suction power is still reduced take out the filter and 
clean mechanically or replace filter.

For certain applications, like wet pick up, it is recom-
mended to turn off the automatic filter cleaning sys-
tem. For details see chapter 3.1.

Flow rate warning

CAUTION

Check that all the filters are present and 
properly fitted.
The machine is equipped with a system to 
monitor air velocity and Dust Class H filter 
condition

*)

. Before picking up dust with oc-

cupational exposure limit values, check the 
volume flow monitor.
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 second. The acoustic warning sounds after 
some additional seconds.

Set the diameter setting to the actual hose size.
When LED indicator lights, air velocity is be-
low 20 m/s.
• 

check if container or filter bag is full.

• 

check if air flow is reduced in suction 
hose, tube/nozzle, filter.

When LED indicator lights, Dust Class H or 
HEPA filter is missing, damaged or clogged. 
The filter needs to be installed or replaced to 
obtain needed air flow.

3.6 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 func-
tion the use of an electrical conductive or antistatic 
suction hose is recommended. When inserting the 
optional disposal bag make sure the antistatic con-
nection is kept.

3.7 

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 
activated. In such case switch off the ma-
chine, clean cooling air filter and allow ma-
chine to cool for approx. 5 minutes.

3.8 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.
When this occurs, switch off the machine. 
Disconnect the machine from the socket and 
empty the container. Never pick up liquids 
without the water level limit system and filter 
in place.  
Picking up liquids.
• 

Do not pick up flammable liquids

• 

Before liquids are picked up, always re-
move the filter bag/wastebag and check 
that the water level limit works properly.

• 

If foam appears, stop work immediately 
and emty the tank.
