BOBBIN CASE REPLACEMENT
A special feature of the QuikStitch is the anti-thread jamming bobbin case.
The bobbin case is held in place by a positioning plate which is designed to
flex slightly to allow the bobbin case to move back and forth freely, about 1/16”.

In the event that the bobbin case becomes displaced and does not move freely
or pops out completely, follow the three easy steps below.
STEP 1:
Remove bobbin from bobbin case.
If bobbin case has popped out, put
back in position as follows: Place
bobbin case under position plate so
that screw head is under notch in
position plate. Then, slide the
bobbin case around until the metal
bracket sits between 2 o’clock and 4
o’clock positions. Proceed to step 2.
STEP 2:
Use left index finder to pull bobbin
case toward the right and up, until
lower half of metal bracket touches
the angled edge of the position plate.
Rotate the hand wheel until the
bobbin case rests in its correct
position. Proceed to step 3.
STEP 3:
Check bobbin case for proper
positioning. The screw head should
line up with the seam in the plastic
casing of the machine.
From side view, the top of the bobbin
case will be level with (or slightly
above) the position plate.
