6. STANDARD ADJUSTMENT (MECHANISMS)
6-1. Adjustments required when the belt loop length is changed
6-1-1. Adjusting fork bracket F
NOTE
●
Retract slider base F e so that loop presser
F q does not touch the fork shaft w.
●
Refer to "6-1-2 Adjusting slider base F" on
page 50".
1. Loosen the two bolts r, and then move fork bracket
F t in the direction of the arrow so that it matches
the width between the machine needles, and then
tighten the two bolts r.
NOTE: It will be easier to see the position relative to
the needle hole at this time if the air is released
and the fork shaft y is lowered so that it is
below the presser foot u.
The diameter of the fork shaft, the loop thick-
ness and the amount of looseness will all have
slight effects on the bar tacking position, so
carry out a test sewing to check the position.
2. Loosen the two screws !0 and move the loosen loop
presser plate i as far as possible (approx 0.5 mm)
so that it does not touch the presser foot u and so
that it is parallel to the loosen loop presser set plate
o.
・ Carry out the following adjustments after changing the length of the belt loop.
