The calibration of the operation time is made by Biffi Italia S.r.L
according to customer requirements and to technical data-sheet
included in technical documentation. If necessary it’s possible to
modify or reset the operating time through two flow regulation valves
(optional) placed on inlets of hydraulic cylinder (see Picture 12 and
the applicable operating diagram).
