    Is it possible to interrogate the parameters on this machine to alter the knife after run time. We have fitted a new clutch complete. Gaps set good yet we still intermittently get error 703.the measured stopping performance in Milli seconds of the knife stopping is good example 80ms. On the machines I test this is good and no other machine has this problem. That is why I wish to know what it is set at
    Thanks

    Hi sir:
    the error 703 cause:
    This message is caused by an "excessive" afterrun of the knife, detected by the
    computer. Although the machine can still be operated with the calculated afterrun,
    the cause for this increase in afterrun ought to be analyzed and eliminated by a
    service engineer.
    Remedy:
    Inspect main clutch (fouled by oil, brake air gap too wide, friction value of
    linings).
    - Check magnetic clutch (iron air gap and / or brake springs).
    - Check mechanical gear play.
    - Bleed the gearbox
    - Make sure, there is no excessive V-belt tension.
    - Replace springs in brake plate (as on model 78)
    - Replace KAP- board (X4).
    - Install new version of brake linings (115 = id. no. 48170, 137 = id. no. 48171,

    Blessing
