Auto-On/Off socket outlet for power tools

CAUTION

 Appliance socket.

The appliance socket is designed for electrical 

auxiliary equipment; see technical data for refer-
ence.

1. Prior to plugging in an appliance, always switch

off the machine and the appliance that is to be
connected.

2. Read the operating instructions to the appliance

to be connected and observe the safety notes
contained in these.

An appliance socket with earthing contact is inte-
grated in the machine. An external power tool can 
be connected there. The socket features permanent 
power on, when the electrical switch is in position 

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

cord.

In position AUTO 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 AUTO ensure 
that the tool connected to the appliance socket is 
switched off.

3.3 

AutoClean

The machine is equipped with an automatic filter 
cleaning system, AutoClean. 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:

1. Switch off the machine.
2. Close the nozzles or suction hose opening with

the palm of your hand.

3. 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.

3.4 

Flow rate warning

CAUTION

Check that all the filters are present and prop-
erly fitted.

The machine is equipped with a system to monitor 
air velocity. Before picking up dust with occupational 
exposure limit values, check the volume flow moni-
tor.

1. When the motor is running, hold the suction hose

shut to reduce the volume flow. The LED indica-
tor on front panel will light after approx. 1 second.
The acoustic warning sounds after some additional
seconds.

2. Set the diameter setting to the actual hose size.

When LED indicator lights, air velocity is 
below 20 m/s.

1. Check if container or filter bag is full.
2. check if air flow is reduced in suction hose, tube/

nozzle, filter.
