Adjustment Procedures
1) Adjusting the tilt of the presser foot
1 Turn the handwheel and place the feed dog in the position
where the feed dog does not jut out the top surface of the throat
plate.
2 Loosen setscrew 1 and adjust so that the presser fopot sole
comes in contact evenly with the throat plate top surface. Then
tighten setscrew 1.
(Reference) Accurate adjustment can be made by using two
pieces of thin paper to check for even drawing-out tension.
In addition, even contact of the presser foot with the throat
plate top surface is achieved rather easily by tightening
the screw while pushing the right side of the presser foot.
2) Adjusting the micro-lifting mechanism of the presser foot
1 When moving presser lifting lever 2 just a little, perform it with
fine adjustment screw 3.
Results of Improper Adjustment
™ Uneven contact will result in bad
straight material feed, weak feed
power, or puckering.
