on the multi-layered section" from the start of running on the multi-layered section (⑤), the sewing state
shifts to the state of the "cloth puller runs on the multi-layered section of material".

Setting of the sewing data to be used while the cloth
puller runs on the multi-layered section of material is
carried out.
State display on the operation panel:
* Depending on the " S017 The number of stitch-
es to be sewn on the multi-layered section" and
"S068 The number of stitches at which the cloth
puller runs on the multi-layered section", the state
of the presser foot side may remain in the "state
of sewing the multi-layered section of material".
The following data items are used.
S004 Limit of sewing speed
S078 Presser foot pressure when the cloth puller runs on the multi-layered section
S071 Cloth puller pressure when the cloth puller runs on the multi-layered section
S070 Cloth pulling amount when the cloth puller runs on the multi-layered section
S068 Number of stitches at which the cloth puller starts running on the multi-layered section
S069 Number of stitches during which the cloth puller runs on the multi-layered section
* If the stitch gathering occurs at the multi-layered section of material in the cloth puller, change the
setting appropriately.
After the sewing machine completes sewing of "S069 The number of stitches during which the cloth puller
runs on the multi-layered section" in the "cloth puller runs on the multi-layered section" state, the sewing
state shifts to the state of the "at section of material".

When the cloth detection sensor detects a material from the "no material state", the sewing state shifts to the
"top of material" sewing state.
(①Return to the sewing of the top end of material)
1. Regardless of the current status of sewing such as the sewing of the at section or that of
the multi-layered section of material, the sewing machine state will shift to the "no-material"
state whenever the cloth detection sensor detects the absence of material.
2. False detection of material can occur if the operator places his / her hand under the cloth
detection sensor. Take care not to place the hand under the sensor.

4-4-6. How to edit a step sewing pattern
A step sewing pattern consists of 10 steps at the maximum. Different sewing conditions can be set for each
step on a step-by-step basis.
The condition to be satised to proceed to the next step can be set with "S101 Step changeover condition".
As many as 10 different step sewing patterns can be created.
Step changeover conditionDetails
Number of stitchesWhen the sewing machine completes sewing of the number of stitches set with "S102
The number of stitches for step changeover", the sewing machine proceeds to the next
step.
Material thicknessWhen the material thickness that exceeds the value set with "S103 The sensor value for
step changeover" changes to a value that is smaller than the aforementioned set value (or
the material thickness that falls below the aforementioned set value changes to a value
that is larger than the set value), the sewing machine proceeds to the next step.
Optional inputWhen the sewing machine accepts an optional input, the sewing machine proceeds to
the next step.
Final stepNo further step is possible. When there is no material on the sewing machine, the sewing
machine returns to the rst step.
In the state there is no material on the sewing machine, the sewing machine will not proceed to
the next step.
