    Dear all
    Can anyone help or suggest if you need to tight
    The pincer grippers if it’s necessary to go into
    Perfecting mode on pm 52/2 colour I was told
    That unless he goes into perfecting the pincer
    Cannot come up and he can’t see them clearly
    To tight them with a Allen key
    Pls advice
    Thanks

    By turning the adjusting set screws, you are changing the timing of when the grippers open and close, not "tightening" the pressure. Proceed with caution.

    All peferctor operations have a procedure to do , and you must do it with caution , it s hard to solve a mechanical issue here , we must check and do the operations by our self , what i can say here that some operation we do it on petfecting mode and other on straight mode buy it s difficult to describ all here there isa lot of points to check and a lot of procedure to do to solve your issue .

    in short, dismantle the turning bar then adjust the fixed clamps and after the mobile clamps, fix the new position of the conical pin, and reassemble the bar then adjust the stroke of the pinion and the opening of the clamps in the high position 11mm
