6. The needle
thread comes
out on the wrong
side of the
material.
①
The needle thread tension is not
high enough.
○
Increase the needle thread tension. 13
②
The tension release mechanism
fails to work properly.
○
Check whether or not the tension disc

③
The needle thread after thread
trimming is too long.
○

the right side of
the material.
①
Stitch skipping at the 1st stitch
○
Adjust the hook timing faster by a 1/2
stitch.
②
Needle used and thread used
are thick in terms of the inner
diameter of the intermediate
presser.
○
Increase the inner diameter of
intermediate presser.
③
Intermediate presser is not
properly positioned in terms of
the needle.
○
Adjust the eccentricity between
intermediate presser and needle so
that needle enters in the center of
intermediate presser.

10. Uneven length
of the needle
thread
①
The tension of thread take-up
spring is too low.
○
Increase the tension of the thread
take-up spring.

11. The length of
needle thread
does not
become short.
①
The tension of thread tension
controller No. 1 is too low.
○
Increase the tension of thread tension
controller No. 1. 13
②
The tension of thread take-up
spring is too high.
○
Decrease the tension of thread take-
up spring. 14
③
The tension of thread take-up
spring is too low and motion is
unstable.
○
Increase the tension of thread take-
up spring and lengthen the stroke as
well.
12. The knotting
section of
bobbin thread
at 2nd stitch at
the sewing start
appears on the
right side.
①
Idling of bobbin is large.
○
A just the position of the moving knife. 116
②
The bobbin thread tension is too
low.
○
Increase the bobbin thread tension. 13
③
The needle thread tension at 1st
stitch is too high.
○
Decrease the needle thread tension at
1st stitch.
○
Turn OFF the thread clamp.
13. Wiper fails to
work. (Return is
