Treadle
When carrying out automatic sewing with cutting before sewing, the hammer operates
only after the set delay time has passed.
Setting can be carried out in units of 50 ms.
When a smaller value is set, the amount that the treadle is depressed to reach the work
clamp operating position becomes smaller.
When a smaller value is set, the amount that the treadle is depressed to reach the
sewing machine starting position becomes smaller.
When a larger value is set, the amount that the treadle is depressed backward to reach
the work clamp raising operating position becomes smaller.
After the work clamp has been lowered, the work clamp is raised when the treadle is
moved to the neutral position.
After the work clamp has been lowered, the work clamp is held in the lowered position
even when the treadle is moved to the neutral position, and the work clamp is raised
when the treadle is depressed backward.
When the feed base moves to the forward setting position after sewing is finished, the
work clamp moves while it is still raised.
When the feed base moves to the forward setting position after sewing is finished, the
work clamp moves while being lowered at the same time, and once the work clamp
finishes moving, it is raised.
Raising of the work clamp is not allowed during test feeding.
The work clamp can be raised during test feeding when the following operations are
carried out.
(A) For hand start switch or 2-pedal foot switch operation: Press the work clamp switch.
(B) For treadle operation: Depress the treadle backward.
When test feeding is carried out again, the following operations must be carried out to
lower the work clamp.
(A) For hand start switch or 2-pedal foot switch operation: Press the work clamp switch.
(B) For treadle operation: Depress the treadle.
After automatic sewing is finished, work clamp is raised.
After automatic sewing is finished, work clamp remains lowered.
To raise the work clamp, carry out the following operations.
(A) For hand start switch or 2-pedal foot switch operation: Press the work clamp switch.
(B) For treadle operation: Depress the treadle backward.
