Section 8: Adjusting the Hopping Foot and Presser Bar
Height (Continued)
 IMPORTANT: One of the main causes
of skipped stitches besides timing is the
hopping foot being set too high above
the needle plate .
Page 26
Final Hopping Foot Check: When the machine is run
full speed without fabric under the hopping foot, with
the bottom of the hopping foot set at .5 mm above
the needle plate, the machine should not knock
loudly inside on the hopping block mechanism. If
the presser bar spring inside the presser bar is not
compressed enough it is possible for knocking to
occur at higher speeds .
 NOTE: If knocking occurs at high speeds
after adjusting the machine as per the
previous instructions, you need to add a little
more pressure to the presser bar spring, as
described below.

If a correction is necessary:
• Turn the handwheel until the needle bar is at its
lowest position. This is the position where the
presser bar is also at its lowest position.
• Place the 0.5 mm feeler gauge (Part # QM40133)
under the hopping foot .
• Loosen screw C through the machine front cover
access hole (3 mm Allen driver)
• While holding the tool in screw C, and pushing
down on the tool to maintain internal assembly
contact, push up on the presser bar and hopping
foot to be slightly above the .5 mm feeler gauge to
tighten the presser bar spring. Firmly tighten screw
C. Repeat this process a couple of times until the
internal knocking is minimized or eliminated. The
foot will now be too high above the needle plate.
 NOTE: It may be helpful to add a business
card along with the gage to aid in raising the
hopping foot slightly more each time until the
spring has the correct tension .
• To make the final hopping foot height setting,
loosen the jam nut on the presser bar and rotate
the foot down to 0.5 mm or less above the needle
plate . Center the hopping foot ring over the needle
plate hole and firmly tighten the jam nut while
holding the foot firmly.
