5. Thread Wiper Adjustment
BES-916AC
1. Move solenoid arm q in the direction of the arrow with your finger. Loosen three bolts e
and adjust thread hook w for smooth movements.
2. If there is a difference in motion between needle bars No. 1 and No. 9 (No. 12 for BES-1216AC),
loosen four screws r and make an adjustment by moving thread presser base t in the
direction of the arrow.
Make sure that no interference will occur when pressure foot y is raised by the solenoid.
3. Move finger guard plate u up and down, and align the top of finger guard i with the tips of
the needles.
4. After the above steps are complete, check thread hook w for smooth movements.
If the thread hook does not move smoothly, apply grease (Grease Tank BR2 (black)) to the gray part of thread guide
solenoid base ! 0 and check its movements.
Note)
• Care should be taken if the finger guard is inclined. If the finger guard in such a state is pushed exces-
sively toward the needle at the time of color change, it may interfere with the presser foot.
• Then make an adjustment in the crosswise direction by sliding bolt o of finger guard i.
