Pfaff 238-0 User Manual

31. Zeroing the Needle for Straight Stitching
When knob G (Fig. 20) is set on "0", the needle bar must not make any sideways
motion and the machine should sew a perfectly straight seam. To check this setting,
drop the feed dog, place a piece of thin cardboard under the sewing foot and turn
knob G to "0". Rotate the balance wheel forward, then backward, and let the needle
stitch into the cardboard lightly. The needle is zeroed correctly, if both punctures are
exactly In the same spot.
If adjustment is required, slightly loosen the set screw on knob G (Fig. 20), hold the
knob steady and turn the zigzag regulator stud to the right or left, as appropriate. Make
sure the zigzag regulator stud has no end play and tighten the set screw securely.
