Lower the feed dogs. Then, using the QM39401 step gauge, slide the 6mm gauge under
the foot in the normal up position. The gauge should slide snuggly under the foot and not
have any up or down movement.

If an adjustment needs to be made,
locate and loosen the set screw with a
2mm tool on the presser bar block.
Grab the presser bar and move it up or
down accordingly; then lightly tighten
the screw. Recheck using the gauge.

Before
tightening the screw
completely, check the radial angle of the
presser foot. The foot should be aligned
with the feed dogs.
