1) Fully raise latch 2 of bobbin case 1 until it stops,
and take the bobbin case out of the hook. The bob-
bin fitted in bobbin case 1 will not come off the
bobbin case by holding latch 2withngers.
2) To install the bobbin case in the hook, be sure to
raise latch 2andfullytthebobbin caseoverthe
hook driving shaft. Then release latch 2 to let it
down.

Pl eas e u se the accessory exclus ive
bobbin case. Also, if it is not pushed in
far enough, bobbin case 1 might fall
out during sewing. So, be careful.
1) Hold the bobbin in a way that the thread open end
is directed to the right as observed from you, and
set the bobbin into the bobbin case.
2) Pass the thread through thread slit
, and pull the
A
thread in direction B. By so doing, the thread will
pass under the thread tension spring and come out
from notch C.
3) Check that the bobbin rotates in the direction of the
arrow when bobbin thread D is pulled.

.
3) Push bobb in pre sser 3 toward the bobbin (in
the direction of arrow E), and the bobbin winder
will start winding the bobbin. It will automatically
stop winding the bobbin when the predetermined
amount of thread has been wound round the bob-
bin (80% of the outside diameter of bobbin).
4) To adjust the amount of thread to be wound round
the bobbin, loosen screw
and change the po-
4
sition of the bobbin presser. (Moving the bobbin
presser in the direction of arrow F will increase the
amount of thread to be wound round the bobbin.)
1. The bo b b i n wi nder wi l l n ot act u ate unless breaker 5 of the seesaw
type switch is in its ON state (where
the white engraved marker dot can
be observed). It means that you can
use breaker 5 as the bobbin winder
switch.
2. There a r e ti m e s wh e n even when
breaker 5 is ON (the white dot is visible), the bobbin winder fails to operate. This means that inside, the breaker is actually OFF. Turn the breaker
OFF and back ON.
3. Be sure to use the JUKl’ s genuine
bobbins and bobbin cases.
4. When threa ding the bobbin thread
from thread guide arm B to tension
controller C, x thread stand disc A
in such a position that the disc A and
arm do not interfere with the bobbin
thread path between B and C.

(1) Bobbin winder circuit protector
1) When the bobbin winder is operated, it sometimes
happens that thread 1 catches on something, pro-
ducing a force that tends to stop it from winding (
direction).
2) In such a case, to prevent the motor from burn-
ing out, circuit protector 2 operates to temporarily
break the circuit inside the bobbin winder, stopping
the winder.

turn the post with the screwdriver. Turning the post
clockwise (in direction A) will increase the stroke.
Turning it counterclockwise (in direction B) will de-
crease it.
(2) Adjusting the pressure of thread take-up
spring
1) The pressure of the thread take-up spring should
be adjusted to 0.15 to 0.25N when it starts pulling
the thread.
2) Fit a flat-bit screwdriver in the groove in tension
post 3, and turn the tension post clockwise (in di-
rection A) to increase the pressure of thread take-
up spring, or counterclockwise (in direction B) to
decrease it.
,
1. When adjusting the stroke of thread take-up spring, the position of the thread breakage detecting plate should also be adjusted. Adjust the position of the thread breakage detecting
plate so that it always comes in contact with the thread take-up spring when the thread take-
up spring is not threaded. (Deection of the spring is approximately 0.5 mm)
* Do not adjust the stroke of thread take-up spring using the thread breakage detecting plate.
Doing so may result in thread take-up spring breakage.
2. Conrm that the tension disc comes in close contact with the thread take-up spring after the
stroke of thread take-up spring after the stroke of thread take-up spring has been adjusted.
If the tension disc does not come in close contact with the thread take-up spring, Ioosen
sorew 2 in the tension post socket, and draw the tension post in direction 4 to make the
