(1) Removing the bobbin case
1) Open cover ❶ . Then, the bobbin can be
changed.
2) Raise latch A of bobbin case ❸ , and remove the
bobbin case ❸ and the bobbin ❷ .
Check the position of your hands and the
locations of goods before opening / clos-
ing cover ❶ so as to prevent the goods
from being caught under the cover and
to prevent bodily injury.
In addition, do not push cover ❶ with
your hands placed on it.
(2) Installing the bobbin
1) Set the bobbin ❷ into bobbin case ❸ in the direc-
tion shown in the figure.
2) Pass the thread through thread slit B of bobbin
case ❸ , and pull the thread as it is. By so doing,
the thread will pass under the tension spring and
be pulled out from thread hole C.
3) Pull out the thread by 50 mm from thread opening
C.
If the bobbin ❷ is installed in the bobbin
case orienting the reverse direction, the
bobbin thread pulling out will result in an
inconsistent state.
(3) Installing the bobbin case
1) Place the bobbin case in the hook with its knob A
tilted and fully push it into the hook until you hear
it click.
2) Close cover ❶ .
If it is not fully inserted, bobbin case ❸
