Adjustment Feed dog height
[Standard]
• When the feed dog is its highest position, the feed dog height from the surface of the
needle plate should be 1 ±0.1 mm (0.9 to 1.1 mm).
• When the feed dog is its lowest position, the feed dog is 0.3 mm or more lower than the
surface of the needle plate.
[Adjustment]
1. Remove the presser foot and the presser foot holder.
2. When the needle plate assy is removed, attach the needle plate assy.
3. Turn the pulley by hand and move the feed dog to its highest position.
4. Insert the hex wrench into the hole of the needle plate, and adjust the feed dog height from the surface of the
needle plate by turning the vertical adjuster screw.
*Key point
• Loosen the vertical adjuster screw. (turn to the direction of “a”.) → The feed dog is lowered.
• Tighten the vertical adjuster screw. (turn to the direction of “b”.) → The feed dog is raised.
