Baby Lock Tiara III Instruction Manual
Handwheel Won’t Rotate
Corrective Measure
•
Thread is entangled and caught in
the hook
•
Turn off the machine and remove the power plug from the electrical
outlet. Remove the bobbin case from the machine. Lubricate the
hook, then manually rotate the handwheel clockwise and counter-
clockwise several times. Remove the thread caught in the hook.
Thread Nests Under the
Quilt
Corrective Measure
•
Not enough tension on top thread
•
Check that the machine is threaded correctly. Make certain that the
thread is flossed snugly in place between the two tension discs. If the
machine is correctly threaded, tighten the top tension by rotating the
tension knob clockwise.
•
Improper threading
•
Refer to the threading diagram and threading instructions in the
section titled Threading the Machine.
Motor Fails to Run
Corrective Measure
•
On/Off switch is off or power cord
is loose
•
Turn the machine on only by using the switch on the back of the
power pod. Verify the power cord is plugged in tightly at both the
machine and the power source.
•
Foot pedal is unplugged
•
Verify that the foot pedal is plugged in. If the main screen status
message in the upper left hand corner states “Check Pedal”, then the
pedal is not properly installed.
Needle Thread Breaks
Corrective Measure
•
Top and bobbin tension not
balanced
•
Check the tension of the top thread tension assembly and bobbin
for proper balance. (See B
obbin Case and Bobbin Thread Tension
Adjustments
and
Top Thread Tension Adjustment.
)
•
Thread cones/spools are poor
quality or may have severe twisting
or thread rot
•
Look for severe twisting of threads when approximately 12 to 15
inches has been pulled off, with ends pinched together. Cotton
threads are particularly susceptible to dry rot which makes thread
brittle. Do not use poor quality thread, or thread that is rotted or
brittle.
•
The machine head has been
threaded incorrectly or thread
spools are not positioned correctly
•
Check that the machine is threaded correctly.
•
Inspect for accidental double wrapping of thread on thread guides.
•
Inspect the thread antennae making sure the eyelets of the antennae
are directly over the spools.
•
Inspect the vertical positioning of the thread cones. Tipped cones can
dramatically affect thread tension and can cause breakage.
•
Particles in tension discs
•
Inspect for particles and remove any lint or debris.
•
Bobbin rotation is not smooth
•
Change the bobbin. The slightest hesitation of the bobbin rotation
can be the cause of dramatic tension change and thread breakage.
Use ONLY Baby Lock bobbins
