HOW TO REPAIR THE MACHINE

1) Adjusting the height of the needle bar

Loosen the needle bar clamp screw① at its
lowest point, adjust the upper punched mark of
the needle bar to conform to the bottom of the
needle bar bushing as shown in the Figure28,
then tighten the needle bar clamp screw①.

2) Adjusting the needle and the shuttle

B. After unfastening the shuttle drive screw①, open the inner hook pressure bar ② left to right and remove

the shuttle Race ring ③ from the (large) shuttle ④.

C. Make the shuttle hook point 󳟆 accord with the center of the needle. And make the needle and the front

face of the shuttle drive 󳟇 connect each other to prevent the needle from curving. Then, tighten the drive
screw ① firmly.

D. After unfastening the (large) shuttle screw⑤, turn the large hook adjustment shaft ⑥ to the left to right

and adjust the (large) shuttle ④ so that the needle and the shuttle hook point 󳟆 is 0.05~0.1mm apart
from each other.

E. After adjusting the (large) shuttle ④ in place, adjust the rotary direction of the (large) shuttle ④ so the

needle and the (large) shuttle ④ is 7.5mm apart from each other.
Then, tighten the (large) shuttle screw ①.

A. As shown in the Figure29, go up the needle

bar from its lowest point, and conform the
lower-left punched mark of the needle bar to

B. Installation and adjusting method of solenoid wiper (SPS/D(C)-B1202-03)

ⓐ Fix the wiper base plate with screw as

shown in the figure41.

ⓑ Fix the wiper base at the opposite

direction with two screws as shown in the
figure42.

ⓒ Connect the connector located at solenoid

with the connector came out from arm.

ⓓ Loosen the base clamp②, adjust

the thread base③ up and down
that the interval between the
thread wiper and the needle
center can be 2.5mm when the
thread wiper and the needle center
are in a straight line, then tighten
the clamp②

ⓔ Loosen the thread crank clamp④,

adjust the thread wiper crank⑤
that the thread wiper under sewing
standby can have the interval of
15~17mm from the needle center,
then tighten the wiper crank
clamp④.

ⓕ Finally, after arranging the

connector as shown in the
figure48, attach the wiper cover
⑥ by using wiper cover joint
screw⑦.

ⓖ The thread wiper spring⑧ attached on the thread wiper base has the function to hold upper thread after

thread trimming, and its proper tension is about 20~30g. (A little stronger than the tension of lower thread
in the bobbin case)If the tension of the thread wiper spring is strong, the thread may come upward the
button.

B. How to adjust the link stopper

ⓐ With the needle bar in its lowest position, check if there is enough clearance between thetrimming

cam roller and both ends of the trimming cam when the trimming drive link is pushed in the
direction of the arrow(󳥝) within the trimming cam moving part.

ⓑ Make the end of the link stopper screw touch part 󳟆 of the trimming link stick when the

trimming cam roller is inserted into the trimming cam moving part. Then, tighten the nut.

Caution

If there is not enough clearance between the trimming cam roller and both ends of the
trimming cam,

trimming may not be operated correctly or the machine may be lock when

beginning to sew or trimming.

Caution

If the position is not set appropriately, the return to the previous point after trimming may be
delayed and the first stitch may not be tight enough.

F. Adjusting the Moving Knife and the Fixed Knife

ⓐ When the needle bar stops at the upper position, use the trimming lever adjustment screw to

adjust space A between the thread separation point of the moving knife and the needle plate hole
as indicated in the table.(4.5mm)

ⓑ Use the fixed knife screw to adjust space B between the fixed knife and the needle plate cover as

indicated in the table. (0.5mm)

ⓒ after the adjustment, check the position of the mes by manual trimming operation.
