    DoS only runs in “ADD” direction

    I have 2 DoS units.
    All 4 heads only run in “ADD” direction even when “remove” is selected in the program.

    any help is appreciated.

    Do you have them on AUTO? All heads run in the add direction when using the prime button or manual ON.

    You might be an engineer if...You have no life and can prove it mathematically.

    Thank you for the response. I did not know this info.
    I do have them in auto, but I was priming them. Well attempting to empty the lines and flush them.
