The presser foot pressure should be as light as 
possible, yet be sufficient to produce uniform 
stitches and feed the fabric properly. 
If the pressure is too light, the fabric may not be fed 
evenly or skip stitching and/or uneven stitching may 
occur.  Adjustment is made by loosening screw A 
and turning adjusting screw B. 
To increase the pressure, turn adjusting screw B 
clockwise.    To decrease the pressure, turn adjusting 
screw B counterclockwise.

To reassemble the presser foot 
Move the presser bar all the way to the up position 
by pressing the presser foot lift pedal. 
Install the presser foot with screw A. 
Make sure the presser foot is replaced onto the flat 
spot of the presser bar.  The needles should drop 
into the centers of the needle drop holes on the 
presser foot.  To make this adjustment, loosen 
screw B of the presser bar clamp and turn the 
presser bar. 

To adjust the presser bar clamp 
Loosen screw B of the presser bar clamp with the 
presser foot tightly rested on the top surface of the 
needle plate.    Clearance between presser foot link C 
and screw D should be approximately 0.5mm.

With the presser foot tightly rested on the top 
surface of the needle plate (the presser foot lift pedal 
is not pressed), there should be a clearance of 
approximately 0.5mm between presser foot link C 
and screw D of the presser bar clamp. 
To make this adjustment, adjust screw J on the 
presser foot lift lever or screws L.
