Removing & Installing
Bobbin Case
21
The bobbin case (B) is located on the underside of
the machine beneath the presser foot (21).
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 (F).
The finger of the bobbin case (G) should fit into the
retaining ring’s notch (H).

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 (H). Bobbin
thread should loosely dangle.
