Adjusting the Hopping Foot
The HQ Sweet Sixteen 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 hopping foot should be no more than 0.5 mm above
the needle plate when the needle is in the lowest position.
It is permissible for the hopping foot to touch the needle
plate.
The end user may have adjusted the hopping foot at the
threads. This usually can be corrected as stated below.
If a correction is necessary:
• Hold the hopping foot, loosen the jam nut, screw the
hopping foot shaft to the desired height. Make sure the
ring is centered on the needle, Tighten the jam nut.
(8
mm open end wrench)
• Note: Make sure you hold the hopping foot while tight-
ening and loosening the jam nut as shown
(Figure 7.6).
•
Warning: if the jam nut is not properly tightend the
hopping foot may become loose and be hit by the needle
causing serious machine problems.
