Regalia Service Manual
Adjusting the Hopping Foot
The Regalia features the KinetiQuilt hopping
mechanism; allowing the hopping foot to move (hop)
up, down and dwell on the fabric when the needle is
in the fabric. This allows fabric to move through the
machine similar to a normal sewing machine with a
feed dog. The dwell time allows for a longer hesitation
of the hopping foot on the fabric and completion of the
stitch cycle. The results are better tension, less needle
breakage and increased hook life.
The initial setting of the presser bar height is 1.5”
from the bottom of the jam nut to the needle plate
surface with the needle and presser bar in their lowest
position. This helps set the proper internal spring
pressure on the presser bar along with the setting on
the presser bar guide block inside the machine. When
properly set, the spring tension will be sufficient to hold
the fabric properly during stitching and also keep the
presser bar from knocking at high speeds.
The customer may be tempted to change the foot
height at the jam nut to sew a thick quilt or one with
thick seam allowances. This can cause stitch and
noise issues .
Check: There should be about 7 (6 to 8) threads
showing below the jam nut on the quick change mount
adaptor. If this has been screwed way in or out it will
affect the spring tension on the presser bar.
If a correction is necessary:
• Hold the hopping foot firmly, loosen the jam nut with
an 8 mm open end wrench, and screw the foot until
it has 7 threads showing below the jam nut (5 mm
from jam nut to top of foot). Make sure the foot is
centered on the needle plate hole .
• Tighten the jam nut firmly while holding the foot
firmly, being careful not to scratch the foot or mount
adaptor .
NOTE: This is the initial setting of the presser
bar, not the final setting.
Tools required: 8 mm open end wrench.
