How I Adjust My AVL Mechanical Dobby

        Dobby Depth 1     Here are 2 pictures to help you adjust the depth of the dobby head. Note that you will want to test harnesses 1 & 16 - if they both lift properly then both sides are adjusted properly. Tighten the lock nuts carefully afterwards so the dobby head does not vibrate out of position.
        Dobby Depth 2     Here are the left and right set-screws.   Make sure you use the correctly-sized allen wrench.   Use the allen wrench to keep the set screw from moving while you use a wrench to turn the lock nut counter-clockwise to loosen. Give the nut a couple of counter-clockwise turns so you can freely adjust the set screw with your allen wrench. When the adjustment is complete use the allen wrench to hold the set screw in place while you re-tighten the lock nut with the wrench (turn clockwise).
