4 Maintenance / Care
4.1 Safety measures during cleaning and maintenance of the machine

Before any maintenance or cleaning work is carried out, the machine must be sepa-
rated from the mains with the main switch being set to "0“ and the mains plug discon-
nected. This will prevent accidents caused by electrical voltage or moving parts.

During cleaning or maintenance work on the machine, when parts are being replaced
or new equipment fitted for a new function, care must be taken that the machine can
not accidentally start, roll or turn over and that no parts can fall down or flap closed.
If the operator has any questions or doubts regarding safety, he must request advice from
the manufacturer or the relevant sales agent before starting the machine.
