8. Adjustment of top feed foot height
Requirement:
At its highest working position the top feed foot must be 2 mm higher than the lower edge of the zigzag
foot (fig. 13).
Note:
This adjustment must only be carried out when the height of the presser bar is set correctly!
Check:
z Raise the presser bar lifter.
z Fit the zigzag foot.
z Engage the top feed.
z Turn the handwheel until the needle bar is at its lowest position.
Caution: The handwheel must now no longer be turned!
z Lower the feed dog.
z Fully raise the presser bar lifter and hold it in this position.
z At the same time, insert presser foot gauge No. 63-114690-35 from the rear under the zigzag foot and
into the cutouts of the needle plate.
z Lower the presser bar lifter to its raised position again.
z Press the top feed foot 28 about 2 mm upward against the pressure of the spring and release it.
z Check that the top feed foot rests only lightly on the presser foot gauge and has no play.
Adjustment:
z Loosen screws 24 and 25.
z Push counter bearing 29 lightly downward until the top feed foot 28 rests lightly on the presser foot
gauge.
z Tighten screw 24 in this position.
Cross-check:

under "Check".
