Installation and regulation of machine
elements
Before carrying out any works on the machine it
must be disconnected from the mains.
Do not draw up the fastening elements
too tight to avoid damaging the thread.
Mounting / dismounting / setting-up of
some elements is the same for all ma-
chine models, in this case specific mod -
els are not indicated in the illustration.
Mounting / dismounting of a plug, current-carrying
cable, stationary network connection
Some machine models are supplied without plugs
and / or current-carrying cables - they must be installed
before the beginning of the operation�
Machines can also be connected to the network on a
stationary basis (not through a socket)�
Note: the stationary connection of the
machine to the network as well as instal-
lation or replacement of current-carrying
cables, plugs and other electrical units
must be performed only by a qualified electrician or
circuit installer authorized to perform such works.
