Adjustment Procedures Results of Improper Adjustment
Lightly press the needle thread trimmer control lever to the needle
thread trimmer arm, rear (pressing in the direction of f) in the
state that the starting safety hook engages with the starting lever
and fix it with two setscrews.
Move the stop-motion solenoid base up or down to adjust so
that the clearance provided between the stop-motion solenoid
spring and the starting safety lever is 0.5 to 1 mm.

needle thread trimmer control lever
is deflected and the pedal becomes
heavy.
™ If the pressing amount is small (if
there is a clearance), the needle
thread trimmer arm comes out to the
front and the needle thread trimmer
may interfere with the needle.
™ If the clearance is small, starting
may not function.
™ If the clearance is large, the starting
safety lever may not return at the
stop-motion.
