Symptom
Bobbin thread does
not wind neatly on
the bobbin.
Fabric being sewn
with the machine
cannot be removed.
The fabric feeds in
the opposite
direction.
The upper thread
has tightened up.
The thread is
tangled on the
wrong side of the
fabric.
Probable Cause
The thread is not passed through the
bobbin-winding thread guide
correctly.
Bobbin spins slowly.
The thread that was pulled out was
not wound onto the bobbin
correctly.
Thread is tangled below the needle
plate.
The feed mechanism is damaged.
The bobbin thread is incorrectly
installed.
You have not threaded the upper
thread properly.
Remedy
Correctly pass the thread through
the bobbin-winding thread guide.
Move the sewing speed controller
to the right (so that the speed will
be fast).
Wind the thread that was pulled
off round the bobbin five or six
times clockwise.
Lift up the fabric and cut the
threads below it, and clean the
race.
Contact your dealer or the nearest
authorized service center.
Correctly install the bobbin
thread.
Correct the upper threading.
