TO CHECK NEEDLE HEIGHT ADJUSTMENT
Note: All screw locations marked in red are permanent and should not be adjusted.
This adjustment should be checked if machine skips stitches, after machine jams,
or a needle has broken.
Install new needle incorrectly with the scarf to the outside (left) rather than inside
(right), (See Figure 1).
1. Remove shuttle access plate.
2. Remove bobbin case.
3. Remove race cover.
4. Leave hook in shuttle.
5. Reverse needle 180° so scarf faces out (See Figure 2). Tilt machine so that it is
at an angle so you can see the shuttle area. as you turn the handwheel
counterclockwise, the hook will travel clockwise; reverse rotation and travel
counterclockwise to a position where the point of the hook is approximately 1/8"
behind the needle and reverse the rotation again. When the point of the hook is
just in line with the back side of the needle, the point of the hook should be in the
center of the scarf (approximately 1/8" above the center of the eye of the needle).
NOTE:
(For adjustments see page 23). Make sure hook is always in full contact with
the bottom most part of driver. When completed, install the needle properly with the
scarf to the right.
