Explanation of operations
Stitching operations
(1) Reconfirm the stitching data before starting. Take special care to the set stitching speed.
(2) The stitching speed is determined according to the set speed and stitch length. The maximum
stitching speed is determined by the speed setting, and the stitch length limits the stitching speed.
[Caution] Do not change the sewing machine stitching speed during operation except in
emergencies. (Changing the speed can cause fault such as thread catching faults.)
(3) Set the material to be stitched, and turn the work holder switch ON. Next, when the start switch is
turned ON, the sewing machine will start rotating and stitching. Once started, stitching will continue
even the operator's foot is released from the start switch. When the stitching is completed, and the
work holder returns to the home position, the sewing machine will stop and the work holder will
automatically rise.
Halting
To stop during the stitching, press the HALT switch (installed on sewing machine head; refer to
following drawing). The sewing machine will stop at the needle UP position. (Standard default setting.)
To cancel the halted state, turn the HALT switch in the direction of the arrow. The following operations
will be possible when the halted state is canceled.
(1) Restart of stitching by pressing start switch (gray pedal)
(2) Movement to stitching start position with forward jog/reverse jog keys.
(3) Lifting of work holder by pressing work holder switch (black pedal)
(4) Change of stitching speed by setting stitching speed
(5) Lifting/lowering of presser bar lifting
[Caution] The needle position during the halted state can be set with the program mode
