stitch is stabilized.
2) Effective/ineffective of the knot-tying functon can be selected.
3) Operating/non operating of the wiper can be selected.
In case the wiper is installed and set to the non-operating setting, when the pattern without crossover
thread is selected, the wiper works only when the crossover thread is trimmed, and it does not work after
thread trimming at the time of completion of sewing.
In case of the pattern with crossover thread as well, the wiper does not work after thread trimming at the
time of completion of sewing with this setting.
In case of the setting of operating the wiper, the wiper always works at the time of thread trimming.
(1) Starting of the memory switches
In the state that ＋/−switches 2are simultaneously
pressed, turn ON the power, and the memory switches
are in the state of setting.
At this time, “ ” is displayed in display section A 3 .
Press set ready switch 5and all 5 stitch shape
selection LEDs 9flash on and off. This state means

Tension post No.1 1is used to adjust the thread
tension to sew on the button and a relatively low tension
will be enough.
Tension post No.2 2is used to adjust the thread
tension applied to the root of the button sewing stitches.
This tension must be higher than that of the tension
post No.1 and be adjusted according to the sewing
conditions.
Turn the respective nuts clockwise to increase the
thread tension.

2. Adjustment of thread hauling amount
Adjustment of thread hauling amount is performed by
loosening setscrew 1and move the position of thread
guide 2.
When the end of thread is drawn from arrow hole A in
the button after sewing, move the thread guide in the
direction of Ain the figure, and the end of thread is
drawn from arrow hole B in the button, move it in the
direction of Bin the figure so that the end of thread is
not drawn.

3. Timing of thread tension release
Turn the hand pulley as you draw the thread in the
direction of the arrow as illustrated and you will find a
point at which the tension disk on tension post No.2
releases the thread. At this moment, the standard
distance from the top end of the needle bar bushing
(upper) to the top end of the needle bar is 54 to 56
mm. Perform the following adjustments especially
when the undermentioned troubles occur frequently.
Loosen nut 1, insert the blade of a screwdriver to
the top slot of tension post No.2, and turn it in the
direction of the arrow to decrease the height of
the needle bar, or in the reverse direction of the
arrow to increase it.

When the machine fails to form a seam at the start of
sewing and starts to form it after it has run a while,
adjust the thread tension guide on the face plate if the
aforementioned trouble cannot be corrected by
adjusting the thread pull-off lever.
1) If the machine fails to form a seam at the start
of sewing, reduce the thread tension by turning
