) Ft bobbn 1 over bobbn wndng shaft 2 .
2) Pass the thread as llustrated n the fgure, and
wind the thread round bobbin four or five times in
the drecton of arrow D .
3) Push bobbn presser 3 toward the bobbn (n
the drecton of arrow E ), and the bobbn wnder
wll start wndng the bobbn. It wll automatcally
stop wndng the bobbn when the predetermned
amount of thread has been wound round the bob-
bn (80% of the outsde dameter of bobbn).
4) To adjust the amount of thread to be wound round
the bobbn, loosen screw 4 and change the po-
ston of the bobbn presser. (Movng the bobbn
presser n the drecton of arrow F wll ncrease the
amount of thread to be wound round the bobbn.)
1. the bobbin winder will not actu-
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 are times when even when
breaker 5 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 C .
