WARNING :

When adjusting the sensor, neither put your hand close to the needle entry area nor put your foot on the pedal in order to protect against injuries.

❶

* This LED is intended to improve operability

of the sewing machine and is not intended for

maintenance.

The sewing machine is provided as standard with an

LED light which illuminates the needle entry area.

Intensity adjustment and turn-off of the light is carried

out by pressing switch ❶. Every time the switch is

pressed, the light is adjusted in intensity in ve steps

and is turned off in turn.

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

❶

feed dog and remove the feed dog. Then, replace

the feed dog with an appropriate one.

Each of the feed dogs for heavy- to

❷

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

❶

❷

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

❷

appropriate one.

– 14 –

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.

3-12-4. Replacing the needle thread guide

rials (standard)

❶

❷

❸

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.

When you turn ON the power to the sewing machine, the sewing screen for the pattern that is currently se-

lected is displayed.

This sewing machine is able to sew free sewing patterns and step sewing patterns. As many as 99 different

sewing patterns can be created by combining free sewing patterns and step sewing patterns.

In the case of a free sewing pattern, different sewing conditions can be adopted respectively for sewing at

sections and multi-layered sections of material.

In the case of a step sewing pattern, separate sewing conditions can be adopted for sewing a material on a

step-by-step basis.

The below-stated section of this Instruction Manual describes the free sewing patterns. Refer to

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.

4-5-2. Counter function

This function counts sewing in the predetermined unit and gives a visible alarm on the screen when the pre-

set value is reached.

The following counters can be used.

Display on the

sewing screen

Display on the counter

setting screen

Content

Sewing counter (count-up counter)

The current value shown on the counter increases one by one.

When the current value reaches the set value, the "count completed"

screen is displayed.

Sewing counter (count-down counter)

The current value shown on the counter decreases one by one.

When the current value reaches "0" (zero), the "count completed" screen

is displayed.

Pitch time counter

The current value shown on the counter increases one by one.

In addition, the counter value also increases by one every time the preset

pitch time is reached.

The timing at which the current value shown on the sewing counter is as shown below. It can be changed

over according to the setting of "U014 Sewing counter function".

Set value of

U014

2 The sewing counter increases by one when an external input is accepted.

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.

❷

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

②

• 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.
