Put the tool in horizontal position and slowly pour in the hydraulic oil (ISO VG 32 type)

Connect the tool to compressed air line and start up a couple of idle cycles. Stop pulling the trigger and slowly
loosen screw

On a periodic basis check the state of wear of the screws and of the heads and, if necessary, replace them as indicated in
section 6.2.
