Adjustment Procedures Results of Improper Adjustment
Adjust the position by increasing or decreasing the number of
pieces of the needle thread trimmer locking bracket latch spacer
(B2023761000).
(Caution) Make sure of the relative position of the needle
thread trimmer and the needle thread trimmer
actuating plate since the position is related to the
position where the needle thread trimmer holds
the needle thread. Then, increase or decrease the
number of pieces of the spacer.
1. Loosen the setscrews in the needle thread locking bracket
latch and move the latch back and forth to adjust the timing.
2. Moving the latch to this side will shorten the period of retaining
the needle thread. On the contrary, moving it to the rear will
lengthen the period of retaining the needle thread.
<Check after the adjustment>
After adjusting the trimmer, move the feed and make sure
that the trimmer does not come in contact with the presser
foot or needle when the trimmer opens.
