Proper needle to hook relationship is required to prevent skipping of stitches on various
fabrics and to prevent hook and needle damage.
If the needle is too far from the hook, the hook point will be unable to pick up the needle
thread loop and skipping of stitches will occur. If the needle is too close to the hook, the
hook point will strike the needle as it passes and may cause damage to the hook point or
needle breakage.
Before attemptinq any adjustment, needle location and hook timing must be verified. Also,
visually inspect the hook point for any damage. If the point is bent or burred, it must be
replaced.
1. Set the machine for straight stitch, center needle position.
2. Remove presser foot, needle plate and bobbin case.
3. Install a size 18 needle.
4. Turn the hand wheel toward the front of the machine until the point of the hook is
directly behind the needle. There should be a 0,00 mm (.000") interference to a 0,10 mm
(.004") clearance between the point of the hook and the needle (illustration A).
1. Remove needle plate, bobbin case, face plate cover, arm top cover, light, light socket
and light shield.
2. Loosen screws (A), (B) and (C).
3. Pivot the head end assembly (D) on screw (A) front to back to obtain the proper distance
between the needle and the hook point. (illustration A).
4. Securely tighten screws (A), (B) and (C).
