5. OPERATION OF THE SEWING MACHINE
5-1. How to operate the pedal (In the case of the direct-drive type sewing machine)
*
Thread trimming operation is only carried out on the sewing machine provided with a thread trimmer.
*
When the auto-lifer (AK device) is used, one more operating switch is provided between the sewing ma-
chine stop switch and thread trimming switch.
The presser foot goes up when you lightly depress the back part of the pedal D, and if you further depress
the back part, the thread trimmer is actuated. When starting sewing from the state that the presser foot
has been lifted with the Auto-lifter and you depress the back part of the pedal, the presser foot only comes
down.
•
If you reset the pedal to its neutral position during the automatic reverse feed stitching at seam start, the
machine stops after it completes the reverse feed stitching.
•
The machine will perform normal thread trimming even if you depress the back part of the pedal immedi-
ately following high or low speed sewing.
•
The machine will completely perform thread trimming even if you reset the pedal to its neutral position
immediately after the machine started thread trimming action.
