PREVENTIVE MAINTENANCE - S/N : 1942-2014
     The machine building is mainly mechanical, so it doesn’t need continuous and assiduous maintenance. For perfect and long usage, we hereby list a series of intervention tasks and how often they should be performed. To guarantee perfect and continuous working, we suggest you follow the flow-chart below indicated.   All maintenance works must be performed at machine stopped, the electric supply and pneumatic system OFF (at zero).  Switch off power to the control panel by rotating the switch inside the panel from the “1” position to the “0” position and lock it.    All maintenance, installation, start-up, handling, inspection and repairs operations must be performed and followed by pertinent skilled personnel only in charge to provide these works. Before to execute any operation on the frequency inverters, ensure that no power is supplied to the unit. In addition, since these units can keep power for seconds even after switched off, wait for 3-5 minutes minimum before acting on the power terminals and generally be careful to all internal powered parts marked with caution signals. Inverters contain components sensible to electrostatic discharge.   To avoid damages, before acting on the connections, personnel must check not to be electrostatic. Before performing any work to the pneumatic system, ensure the compressed air pressure switch shows “ 0 “. All maintenance works must be performed at machine stopped, the electric supply and pneumatic system OFF (at zero). Before to perform any work to the pneumatic system, ensure the compressed air pressure switch shows “ 0 “.   If , during maintenance operations, the operator will be in an area situated in the back of the machine or will be hidden from the sight of the people situated in front of the same machine, a sign will have to be placed close to the pushbutton panel.
