QUILT MAKER PRO 16
• Since thread slides over the surface of the bobbin case at a high
speed, make sure the case is free of any lint or foreign matt er that
could impede thread passage through the machine.
• Synchronize machine movement and needle speed to get roughly
8 to 10 sti tches per inch. Elongated sti tches are an indicati on of
moving the machine too fast for the current speed.
Correcti ve Measure(s)
• If using short staple threads, inexpensive, or industrial threads,
or coated threads, lint and other material will build up under the
tension spring and begin to lift the spring, reducing the spring's
ability to compress against the thread. Insert a needle or business
card under the spring and clear out the lint. The bobbin tension
will return fairly close to its preset tension. Test the tension
before quilti ng.
Correcti ve Measure(s)
• 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 ti mes, and then remove
the thread caught in the hook.
Correcti ve Measure(s)
• Check that the machine is threaded correctly. Make certain that
the thread is fl ossed snugly in place between the two tension
discs. If the machine is threaded correctly, ti ghten top tension by
rotati ng the tension knob clockwise. (For more informati on about
adjusti ng tension, see Bobbin and Bobbin Tension and Top Thread
Tension in the Using Your Machine secti on of this manual.)
• Refer to threading diagram and threading instructi ons.
Correcti ve Measure(s)
• Center the carriage wheels on top of the conti nuous track. Check
that the machine carriage has not jumped the track.
• Remove all thread or debris in wheels. Check that the tracks are
free of lint and threads.
