Chapter 10 Adjustment
1. Put the attached T-shaped hexagonal wrench (4 mm) into the hole [1] on the left side of the
machine body, and adjust the arrow plate to align with 180 degrees (N.D mark) to move the needle
bar to the lowest point.
2. Insert the bottom dead center gauge [2] into the rotary hook [3].
3. Loosen the screw [5] of the needle bar clamp [4] and Socket head bolt for top dead center stopper
[8], then move the needle bar up and down until the needle tip touches the gauge [2] lightly.
• The needle point should touch the gauge at a place other than the cutting section.
• The bottom dead center gauge should be set in or removed from the rotary hook with its cutting
section facing upward.
4. Tighten the screw [5] of the needle bar clamp [4] securely.
5. Set the needle bar at the highest position (where the arrow plate and the "N.U.”mark are aligned).
Lightly press the top dead center stopper [6] toward the cushion rubber [7], and tighten Socket
head bolt for top dead center stopper [8] while pressing down the needle bar clamp so that it faces
the front. (Tightening torque: 0.78 N.m)
• Make sure that the top dead center stopper [6] does not hit the needle bar guide rail [9] at this time.
• When tightening the upper dead point stopper bolt [8], insert the longer side of the attached wrench
into the bolt and tighten it by using the shorter side.
Excessive tightening may make the needle bar movement sluggish.
