may be used.
To start the operation of the vac, set the mode
selector switch 6 to on.

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 vac-
uum hose at 5 m length, the air flow
amounts to 39 l/s and the maximum vac-
uum to 204 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 automatically

The socket 7 of the vacuum cleaner must be
used only for the purposes specified in the oper-
ating instructions.
For connecting the power tool, various hose sys-
tems are available as accessories.
