4.5 PNEUMATIC CONNECTION
If the machine is equipped with a pneumatic locking/release spindle and/or zero weight lift, it needs to be fed with
compressed air at 8-10 bar. The compressed air coupling is positioned on the rear of the machine. The compressed
air must be clean and dry. The pipes and pipe fittings must be properly connected by appropriately trained personnel.
The warranty does not cover damage caused by the absence of an adequate air filtration system.
