Setting the Top Feed and Presser Foot Height
The measurement from the bottom of the presser foot to the top of the needle
plate should be 6.5–7 mm when the presser foot is in its highest position. To
achieve this setting, perform the following steps. See

correct components.

pressure on the top feed
and the presser beam to
hold them against the
inner guide.

Remove the outer guide by removing the two socket head cap screws from
the outer housing.

Center the cap screw within the presser foot arm holder slot. Tighten the
screw.

With the presser foot in its highest position, loosen the walking foot drive
crank screw, and manually move the drive crank up or down until the
desired setting of 6.5–7 mm is achieved.
