6. Maintenance

6.1 Particulars

At the first installation and afterwards, at regular intervals

arranged beforehand, it is necessary to take care for the good func-

tioning of the machine, by means of the below mentioned operations of

maintenance.

During these operation special attention should be paid to the

safety provisions.

The inspection and maintenance operations must be carried out only

and exclusively by trained staff, after having cut off the voltage

using the main switch and having insulated the pneumatic circuit, dis-

connecting the feed pipe from the feeding net.

If some safety protections have to be removed, to make the main-

tenance operations easier, the protections must be replaced in their

correct position when the maintenance is accomplished.
