3-12. To use the sewing machine with a cloth puller for sewing heavy-to medium-weight ma-
terials
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.
The MS-1261A has been developed to sew extra heavy-weight materials as standard. Various kinds of gaug­es have been prepared to enable the machine to be used for sewing heavy- to medium-weight materials. Re­place the gauge, when sewing heavy- to mediumweight materials, following the procedure described below.

3-12-1. Replacing the feed dog

Remove the throat plate. Loosen screw ❶ in the
feed dog and remove the feed dog. Then, replace
the feed dog with an appropriate one.
Each of the feed dogs for heavy- to
medium-weight materials has been
designed so that it can be used only
by replacing it without adjusting the
feed dog height. However, it is really
necessary to adjust the feed dog height,
refer to "3-7. Adjusting the feed dog
height" p. 10

3-12-2. Changing the throat plate

To change the height in difference on the
righthand side of the feed dog
Loosen two serews ❶ in the adjusting feed dog and
remove spacer ❷ (plate thickness: 0.5 mm).
Many different types of spacers are available.
Detach throat plate setscrews ❶ (two pieces) and
(one piece). Then, change the throat plate with an
appropriate one.

3-12-3. Adjusting the difference in height of the presser foot

Remove two screws ❷ that are used to retain ad-
justing presser foot ❶, and adjust the difference in
height of the presser foot by replacing spacer ❸.
Thicknesses of spacers that match the respective
throat plates and feed dogs are as shown in the
table.
No. Plate Thickness Specication
(Standard L: 3.5 mm)
1 1.0mm Extra heavy-weight mate-
2 0.5mm Heavy-weight materials 3 None Medium-weight materials
To replace spacer ❸ with a spacer (0.5 mm or
none), replace screw ❷ with a shorter one (L=3.0
mm SS5060310SP).

3-12-4. Replacing the needle thread guide

rials (standard)
When sewing a medium-weight material using a thin
thread, larger needle thread loops will be produced
and they will be likely to tilt causing stitch skipping.
To prevent the aforementioned trouble, replace
thread guide ❶ located above the needle clamp with
an appropriate one.
Loosen screw ❷ that is used to x thread guide ❶,
and replace the thread guide with thread guide ❸ for
medium-weight materials.

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 satised 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 condition Details
Number of stitches When 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 thickness When 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 input When the sewing machine accepts an optional input, the sewing machine proceeds to
the next step.
Final step No 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.

The sewing counter increases by one when the back part of pedal is depressed to its 2nd level by the
set value of "U183 Number of times of thread trimming for the sewing counter".
The sewing counter increases by one after the sewing machine has repeated the sewing sequence by
"U183 Number of times of sewing of materials" (one sewing sequence = when the absence of material
is detected after the sewing machine performs sewing of material). If the number of stitches sewn on
the material is smaller than "U211 Number of stitches for sewing the material while the sewing counter
is enabled", the relevant sewing sequence will be invalid.

It is possible to copy the sewing data using the commercially-available USB thumb drive.
Refer to
thumb drive.
"4-5-8. Communication function" p. 63
Position of the USB connector
for details of how to copy the sewing data on a USB
[USB thumb drive insertion position]
The USB connector is provided on top ❶ of the
operation panel.
To use a USB thumb drive, remove connector
cover ❷ and insert the USB thumb drive into the
USB connector.
* In the case a USB thumb drive is not used,
the USB connector should be protected with connector cover ❷ without exceptions.
If dust or the like enters the USB connector, a
failure can be caused.
Precautions to be taken when handling USB devices
• Do not connect to the USB connection terminal other than the USB memory.
It may cause failure.
• Do not leave the USB device or USB cable connected to the USB port while the sewing machine is in operation. The machine vibration can damage the port section resulting in loss of data stored on the USB device or breakage of the USB device or sewing machine.
• Do not insert/remove a USB device during reading a program or sewing data.
It may cause data breakage or malfunction.
• When the storage space of a USB device is partitioned, only one partition is accessible.
• Never forcefully insert a USB thumb drive into the USB connector while carefully checking the orienta­tion of the USB thumb drive. Forceful insertion of the USB thumb drive can cause failure.
• JUKI does not compensate for loss of data stored on the USB device caused by using it with this sewing machine.
• In principle, connect only one USB thumb drive to the operation panel. When two or more devices/media
are connected/inserted, the machine will only recognize one of them. Refer to the USB specications.
• Do not turn the power OFF while the data on the USB ash drive is being accessed.
