Cautions regarding the setting position of the bobbin changer in the longitudinal direction (Y
direction)
If the clearance provided between the bobbin case that is placed in the sewing machine
・
hook and the chuck is too small when the chuck rests on the sewing machine side,
breakage of the bobbin and hook and mis-chucking can be caused. On the other hand, if the
aforementioned clearance is too large, malfunctions such that the chuck fails to grasp the
bobbin case arm can occur.
Finely adjust the setting position of the bobbin changer in longitudinal direction so that a

signal.
To the sewing machine: "Prohibition of operation"
③
This signal is output from the automatic bobbin changer to the sewing
machine in order to prevent malfunction while the automatic bobbin
changer is automatically replacing the bobbin, or when the manual
mode is selected.
To the sewing machine: "Bobbin replacement completed"
④
This signal is output for approximately 0.5 s upon the completion of
automatic bobbin replacement. It can be used to clear the counter, etc.
To the sewing machine: "Automatic bobbin changer is faulty"
⑤
