13. PRESSER BAR HEIGHT
STANDARD
The height of the presser bar should be such that when the presser lifter is raised (1st-stage lift state), the
distance from the top surface of the needle plate to the bottom surface of the presser foot should be 6.0-6.5 mm.
ADJUSTMENT
1. Raise the presser lifter.
2. Loosen the screw securing the presser bar clamp.
3. Move the presser bar up and down and adjust so that the distance between the top surface of the needle
plate and the bottom surface of the presser foot is 6.0-6.5 mm.
4. Tighten the screw securing the presser bar clamp.
Adjustment Point
3. Check that the side surface of the presser foot and the needle plate feed dog groove are parallel. If the
presser foot is not parallel, the needle may strike the presser foot or the fabric may not feed straight while
overcasting.
Adjust the presser bar height with the feed dog below the needle plate top surface.
