10. SEWING CIRCULAR STITCHES
For -00 and -01 specifications, it is recommended that you use the special parts when sewing. (Refer to the Parts Book.)
<If using a -02 specification sewing machine>
It is recommended that you change to using a -00 or -01 specification sewing machine.
Alternatively, if the version of the main control program (MN) is 1.3.00 or later, simple sewing is possible. However, the following
restrictions will apply, so make sure that you understand them before using the sewing machine.
<Restrictions when using -02 specification sewing machines for sewing circular stitches>
Restriction
Points to note and understand
1
Use standard -02 specification parts for the needle plate and work clamp.
Note that the work clamp range will
become smaller and the amount of play
in the material will increase.
2
The lower thread trimming mechanism will not operate.
Thread trimming will become unstable
because of the way the mechanism
operates, so the mechanism will be set
to be disabled.
3
The only material setting position available is “Front”.
The “Back” setting position would result
in the lower thread and gimp getting
caught on the thread trimming knife
when the material is pulled out at the end
of sewing, and so this setting cannot be
used.
4
Move the position of the block stopper plate (1) used to install the knife back
by 1 mm and install the circular stitch knife (2).
In order to match the seam position to
the standard work clamp, the seam
position for circular stitches is moved
back by 1 mm. As a result, the knife
installation position should also be
moved back.
<Knife pressure>
The cutting area will be smaller than for eyelet shapes, so it is recommended that you decrease the knife pressure.
