    good morning sir and thank you kindly for your response.

    we are sure the issue is not electrical, as the machine can run. the trimmer knives wont sit flush, resulting in bad cuts (either not at all or very roughly).

    the blades are for the trimmer module for the stitcher. weve replaced blades on this unit before with no issues, so i am confident that we did it correctly this time, along with the positioning and adjustments made.

    our troubleshooting guy for this machine spoke to us on the phone, and said the issue may be with the fact that we havent bought new blades for a long time (we have been only sending the blades to get sharpened) and that may have shaved them down too short.

    please let me know if theres more information you need. thanks again!

    understood.
    This is operation like the paper cutter.
    The sharp will be good, otherwise you we have a LOT problem
    Let me know when you have the right Blades, and see if working o.k
    Some machines has limit swtich for protection machine and operator , when you are
    replacing the blades.
