Hand Wheel Won’t
Rotate
Corrective Measure
Thread is entangled and
caught in the hook Turn off the machine and unplug the machine from the electrical outlet. Lubricate the hook,
strongly turn the hand wheel clockwise and if necessary counterclockwise several times, and
then remove the thread caught in the hook.
Thread Nests Under
Quilt
Corrective Measure
Not enough tension on top
thread
Moving the machine too fast
for needle speed selected.
Improper threading
Check that the machine is threaded correctly. Make certain that thread is snugly in place
between the two tension discs. If machine is threaded correctly, tighten top tension by rotating
the tension knob clockwise.
Synchronize machine movement and needle speed to get roughly 6-8 stitches per inch.
Elongated stitches are an indication of moving the machine too fast for the current speed.
Refer to threading diagram and threading instructions (page 7).
Hard to Guide Machine Corrective Measure
Carriage wheels not centered
on track
Thread caught in wheels
Center the carriage wheels on top of the continuous track. Check that the machine carriage has
not “jumped” track. Slightly loosen wheel on one side to allow machine to more easily follow
track
alignment.
Remove all thread or debris in wheels. Check that the tracks are free of lint and threads.
Motor Fails to Run Corrective Measure
On/Off switch turned off
Machine not receiving power
Turn the machine on by using the switch on the back electrical control pod.
Check that the power connector is plugged into the back of the machine and the three-prong
end is plugged into power source
Uneven Quilt Design Corrective Measure
Take-up rollers may be
bowed or bent
Leaders are stretched/worn
Make certain that the fabric is not rolled too tight, causing the fabric to stretch. Check that poles
overlap and snap together with the push pin so bowing won’t occur.
If fabric is beginning to stretch or fray, contact Handi Quilter Company for replacement leaders.
Needle Thread Breaks Corrective Measure
Thread cones/spools may
have abraded thread casing,
severe twisting or thread rot
Top and bobbin tensions not
balanced
The machine head has been
threaded incorrectly or
thread spools are not
positioned correctly
Particles in tension discs
Bobbin rotation is not smooth
Needle is burred, bent or dull,
or installed incorrectly
Needle not suited for thread
Hesitating too long at one
point in pattern
Improper needle/hook
relationship
Damage or “Burr” at needle
hole of throat plate or other
thread handling part
Wrong type of needle
Look for severe twisting of threads when approximately 12 to 15 inches has been pulled off,
with the ends pinched together. Cotton threads are particularly susceptible to dry rot or wet rot
which makes thread brittle.
The top thread tension is many times tighter than the bobbin case. If the bobbin case tension is
too tight, a very tight top tension is required for tension balance. See Page 8-9 for proper
adjustment.
Check that the machine is threaded correctly.
Inspect for accidental double wrapping of thread on thread guides.
Inspect the thread mast, making sure that the eyelets of the mast are directly over the spools.
Inspect the vertical positioning of the thread cones. Tipped cones can dramatically affect thread
tension and can cause breakage.
Inspect for particles and remove any fuzz or debris.
Change the bobbin. The slightest hesitation of the bobbin rotation can be the cause of dramatic
tension change and thread breakage.
Change the needle at least once per quilt. Make sure the needle is installed to the top of the
stop hole in the needle bar
Replace the needle to one better suited for the thread. Use the proper size needle.
Move more quickly so stitches don’t overlap or build up. When starting the machine, begin
moving immediately. Sewing in one place too long will cause the thread to break.
Timing-consult a repair technician.
If thread is shredding at the throat plate, check for burrs or jagged edges. Gently rub with metal
cloth to remove the sharp edge. Consult a repair technician to polish any hard to reach or
delicate areas, or if the burr is inside the throat.
Use needles recommended by Handi Quilter Company. Using the wrong needle with a smaller
shank diameter causes many problems. For example, a system 1738 or 287WH needle with a
shank diameter of 1.64mm will fit loosely into the needle bar clamp. This condition allows the
