Adjustment Procedure
Results of Improper Adjustment
10) Installed length of the thread trimmer connector
bar (asm.)
1. Two connecting sections ❽ of the thread cutter connector rod
are movable. For mounting the thread cutter connector rod,
adjust the length to make the angle between the hole direction
of the two connecting sections ❽ and the axis direction of the
thread cutter connector rod a right angle and tighten the rod with
the nut ❼.
2.Inordertoavoidlooseningbymistakeatthetimeofshipment,
“white paint” is applied to the nuts ❼.
3. Loosen the nuts ❼ when removing the thread trimmer connector
bar (asm.) (40174323) without drawing out the lower shaft. When
the nuts are loosened, the respective subsidiary parts are disas-
sembled and the thread trimmer connector bar can be taken out.
4. After disassembly, reassemble the parts so that the standard
adjusting values can be secured.
11) Installation position of the thread trimming shaft
Installthethreadtrimmingshaftinthepositionsothattheedgeof
the thread trimming shaft is matched with the edge of the bed at the
thread trimming initial position.
○If the two rod ends ❽ are not
crossed at right angles, the ob-
tained torque is the value for thread
trimming.
○Ifthecenter-to-centerdistance(102
± 0.2mm) deviates from the stan-
dard value, the initial position of the
moving knife is changed and this
can be a cause of thread trimming
failure.
