@0 Number of rotations of thread trimming (Function setting No. 36)
Number of rotations of sewing machine at the time of thread trimming is set.
3 6 1
@1 Number of rotation of one-shot stitching (Function setting No. 38)
This function can set, by the pedal operation of one time, the sewing speed of one-shot stitching when the sewing
machine continues stitching until completing the number of stitches specified or detecting the material end.

2 5
(Caution) 1. Setting of one-shot stitching is made by the operation panel of the CP-160, or the
function setting No. 76.
2. The max. number of rotation of one-shot stitching is limited by the model of the sewing machine head.
@2 Presser lifting function at the time of turning ON the power (Function setting No. 46)
Whether making presser go up or making it come down at the time of turning ON the power can be set.

@3 Holding time of lifting presser foot (Function setting No. 47)
Solenoid type presser foot lifter (No. 46 0) can adjust the holding time control of lifting presser foot.
This function automatically lowers the presser foot when the time set with the setting No. 47 has passed
after lifting the presser foot.
When the pneumatic type presser foot lifter (No. 46 1) is selected, the holding time control of lifting presser
foot is limitless regradless of the set value.

@4 Pedal presser lifting function (Function setting No. 50)
Pedal type setting can be changed. Selection of conventional PFL and KFL types can be performed.
5 0
Set value 1 : PFL is the standard. For PFL type in the standard state, the amount of depressing back part of
pedal to make thread trimming motion is large (position of thread trimming motion is deep) since there is an
auto-lifter section.
For this reason, if you feel that the work is hard, setting to KFL type is recommended.
By setting to KFL type, thread trimming motion is performed at a shallow position when depressing the back
part of pedal.
@5 Compensation of timing of the solenoid for reverse feed stitching (Function setting No. 51 to 53)
When the normal and reverse feed stitches are not uniform under the automatic reverse feed stitching action, this
function can change the ON / OFF timing of the solenoid for back tack and compensate the timing.
1 Compensation of on-timing of solenoid for reverse feed stitching at the start of sewing (Function setting No. 51)
On-timing of solenoid for reverse feed stitching at the start of sewing can be compensated by the unit of angle.
