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
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.

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.
