• The presser foot pressure of this machine is
preadjusted at the factory to suit the sewing of
medium weight fabrics.
• Most of the materials do not require adjustment of
presser foot pressure however, there are some
instances where adjustment is necessary when
sewing lightweight and heavyweight fabrics.
• In such case, insert screwdriver through access hole
(A) in top cover and into slot (B) in pressure
regulating screw and turn regulating screw as
required.
Note: Turn regulating screw counterclockwise until
it stops against the top cover. Then turn
screw clockwise 6 turns which will be the
standard presser bar pressure.
