    Hi Guys

    Can anyone tell me how to go about diagnosing an error 84 on the Polar 76EM.
    It happens while doing a cut. The blade will go all the way down then come back up a small bit then it will stop. It seems to be that it stops as soon as s22a is switched on.

    So far I have tested the 42v line is ok at the KUP board, and tried adjusting s22a and s22b up and down but no change.

    If anyone could help, it would be greatly appreciated.


    Kind Regards
    Chris
