Correction
• Decrease the pressure on the hopping foot by loosening the nut at
the base of the hopping foot shaft. Adjust to the proper height.
IMPORTANT NOTE: When tightening the nut on the hopping
foot shaft be careful not to tighten so tight that it rotates the
bar. Remember to readjust back to normal height after quilting
the thick quilt. Take note of how many times you rotated the
foot up to accommodate the thick quilt. When finished,
rotate the foot back down the same number of times to bring
it back to the optimum setting.
• Check that the machine is threaded correctly. Make certain that
thread is "flossed" snugly in place between the two tension discs. If
machine is threaded correctly, tighten top tension by rotating the
tension knob clockwise.
• Refer to threading diagram and threading instructions (page 16).
• Turn the machine on by using the switch on the back electrical
control cover.
• Check that the power connector is plugged into the back of the
machine and the three-prong end is plugged into power source
• Make certain that the fabric is not rolled too tight, causing the
fabric to stretch. Check that poles overlap and snap together with the
snap button so bowing won't occur.
• If fabric is beginning to stretch or fray, contact your authorized Baby
Lock retailer for replacement leaders.
• Check that all cables are connected tightly.
