How to adjust the presser foot pressure
The presser foot pressure of this
machine is pre-adjusted at the factory
to suit the sewing of medium weight
fabrics.
Most materials do not require
adjustment of the presser foot
pressure. However, there are some
instances where adjustment is
necessary when sewing lightweight or
heavyweight fabrics
In such cases, insert a screwdriver
through access hole (A) in the top
cover and into slot (B) in the pressure
regulating screw, then turn the
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.
For lightweight fabric – decrease the
pressure
For heavyweight fabric Increase the
pressure
