8. Adjustment of top feed height
Requirement:
In its highest working position the top feed foot must be 2 mm higher than the lower edge of the zigzag
foot sole (fig. 25).
Note:
This adjustment must only be carried out when the height of the presser bar is set correctly.
Check:
● Raise the presser bar lifter.
● Insert the zigzag foot sole.
● Engage the top feed.
● Turn the handwheel until the needle bar is in its lowest position.
Caution: The handwheel must now no longer be turned!
● Lower the feed dog.
● Fully raise the presser bar lifter and hold it in this position.
● At the same time insert the presser foot gauge (63-114 690-39) from behind under the zigzag foot
and into the cutouts of the needle plate.
● Lower the presser bar to its normal raised position.
● Press the top feed lightly downward.
● Check that the top feed foot rests only lightly on the presser foot gauge and has no play.
Adjustment:
● Loosen screws 34 and 37 (fig. 25).
● Push counter bearing 40 lightly downward until the top feed foot rests lightly on the presser foot gauge.
● Tighten screw 34 in this position.
Cross-check:
● Check for light resting and freedom of play of the top feed foot on the presser foot gauge as described
under "Check".
Adjusting the guide piece
● Fully raise the presser bar lifter and hold it in this position.
● Remove the presser foot gauge.
● Lower the presser bar lifter to its raised position.
● Turn the handwheel until needle bar 44 is in its top position.
● Set guide piece 42 at a clearance of 0.2 mm from cross head 41 (fig. 24).
● Tighten screw 37.
