■To reassemble and adjust the feed roller
1. Insert the feed roller presser bar into the feed

and then feed roller bracket.
2. Replace screw A of the feed roller presser bar
clamp.
Tighten screw A until it contacts the flat spot on
the feed roller presser bar. Tighten screw B.
3. Create a clearance of approximately 0.1mm
between the feed roller and the needle plate with screw E of the feed roller presser
bar clamp touching the surface of the casting on the machine head. Then tighten
screw D.
If the feed roller contacts the needle plate when the machine runs with no fabric, the
feed roller will be worn out. This clearance (0.1mm) prevents the feed roller from
being worn out.
■Interlock between the feed roller and the presser foot
Pressing the presser foot lift pedal raises simultaneously the presser foot and the feed
roller.
The feed roller is factory-set to be raised shortly after the presser foot is raised.
Adjust the timing at which the presser foot and the feed roller are raised according to
sewing conditions. Refer to the procedures below.
1. Loosen screw D to release the feed roller.
