10. FEED DOG, THROAT PLATE, HOOK, BOBBIN CASE, BOBBIN, AND BED SLIDE
(1) Since the feed dog, throat plate, hook, bobbin case, bobbin, and bed slide are specifically
used for thread trimming, be sure to use ones specified by Mitsubishi.
(2) Slip running prevention spring
A conical spring is loaded in the rotating hook
to prevent the bobbin from slip running
during thead trimming.
(3) Bobbin
Use the bobbin which is attached to the
machine. Since the bobbin is made of alumi
num, it easily deforms. To prevent this, wind
the thread as lightly as possible.
