    In QM 46-2, while the Press is in production. The Pile In Table automatically rises step by step BUT there is no corresponding movement in Pile Delivery Table.

    The Pile Delivery needs to be manually lowered in order to avoid Delivery Jams. While Delivery Crank Handle is moved " The Delivery Jam Sensor lights up.

    What may be the problem. Anyone please advise. Thanks in advance

    take non operator side panel off, clean the spring to hold the gear on delivery chain shaft.

    Hi:
    check the clearance at the magnet for the pawl
    movement, of delivery
    Check the distance x. The clearance between
    feeler and lever must be 0.3 mm
    when the pawl is fully disengaged.
    The clearance between feeler and
    pawl must be 0.1 mm when the pawl is engaged.
    Test The position switch S20 recognizes whether the
    crank handle on the delivery is engaged.
    Blessing
