Removing & Installing
the Bobbin Case
The bobbin case (
B
) is located
on the underside of the machine
beneath the presser foot (
7
).
Removing —
Lift the spring loaded lever (
E
)
and pull the bobbin case out. With the lever
held open the bobbin is captive in the bobbin
case. Release the lever and the bobbin will
fall out.
Installing —
Pull and hold the spring-loaded
lever outward (to keep the bobbin from falling
out) and push the case onto the axle of the
gib hook. The finger of the bobbin case (
F
)
should point upward.
If the lever (
E
) is held up until the bobbin
case is completely installed, the lever, when
released, will lock onto the axle and there will
be no clicking sound. If the lever is released
before the bobbin case is pushed completely
in place, there is a clicking sound when the
case is pushed all the way on. The finger of
the bobbin case will drop into the notch in the
hook’s retaining ring (
G
).
