, 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
that the tool connected to the appliance socket is
switched off.

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.

ensure
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
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.

Optional accessories / Option depending on model
*)
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.
Antistatic connection
*)
CAUTION
The machine is equipped with an antistatic
system to discharge any static electricity that
may develop during dust pick-up.
Cooling air filter
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.
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.
