Operating instructions
1. Setting up and installation
1.1 Setting up
Place the unit on a stable, flat work-•
bench.
Position the unit so that the mains plug is•
easily accessible.
1.2 Electrical connection
Ensure that the voltage corresponds to•
the voltage on the rating plate of the unit.
Plug in the unit.•
1.3 Connecting the extractor
The Millo / Millo pro must be
operated with an extractor.
Attach the extractor hose to the connec-•
tor on the unit (Fig. 6).
1.3.1 MILLO PRO
The Millo pro has a plug-in socket.
This plug-in socket has an electrical cur-
rent when the Millo pro is switched on so
that an extractor can be operated directly
with it.
Do not exceed the connected
load for the plug-in socket.
The plug-in socket should only
be used for connecting an ex-
tractor.
Connecting other electrical units
to the plug-in socket could dam-
age the Millo pro.
Plug the extractor into the plug-in socket•
on the back of the Millo pro (Fig. 7).
Section D.1 at the end of these instruc-
tions offers information concerning electri-
cal systems employing different power
plug designs.
The Millo / Millo pro is now ready for
operation.
Information for the purchaser

cation, possible hazards during
use and operation of the Millo /
Millo pro arch trimmer based on
the user information.
Ensure that this user information is avail-
able to operators.
