and wind the thread on the bobbin.
1) Fit bobbin
❶
over bobbin winding shaft
❷
.
2) Pass the thread as illustrated in the figure, and
wind the thread round bobbin four or five times in
the direction of arrow
D
.
3) Push bobbin presser
❸
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
❹
and change the po-
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 bobbin winder will not actuate
unless breaker
❺
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
❺
as the bobbin winder
switch.
2. There are times when even when
breaker
❺
is ON (the white dot is vis-
ible), the bobbin winder fails to oper-
ate. This means that inside, the break-
er 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 threading the bobbin thread
from thread guide arm
B
to tension
controller
C
, fix 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
