ADJUSTING THE PRESSER FOOT
9-1 Presser foot pressure
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.
9-2 Disassembling and reassembling the presser foot
■
To disassemble the presser foot
Move the presser bar all the way to the up position
by pressing the presser foot lift pedal.
Loosen screw A.
■
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.
9-3 Presser foot lift
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.
