    Hi sir:
    Do this:
    1)The claw does not swing
    down to engage with the bolt.
    2) Abort the command.
    3)Repeat the changeover or
    sheet-length change.
    4)Check the pneumatic valve/
    pneumatic connections.
    5) Check the electrical connections
    to the pneumatic valve
    Let me know
    Blessing

    Which pins are you talking about? You need to give a lot more details about your problem if you want help over a forum. Is it a semi or fully auto perfector and what error is showing up on your screen?
