Lowering presser foot:
The presser foot can be lowered in two ways:
1. Manually turn hand lever to position (0).
2. Raise presser foot with pedal. Presser foot rises slightly, hand
lever lock disengages and the internal spring moves the hand
lever back to position (0).
5.11 Setting presser foot pressure
The regulator on the top left of the machine arm determines the
pressure the presser foot applies to the material. The pressure
can be adjusted continuously by turning the regulator.
Correct setting
Set the pressure of the presser foot as low as possible, but enough
so that the material can pass through evenly without slipping
through.
Defects due to incorrect setting
• Pressure too high:
Material is torn by the feed dogs. Feed is very noisy.
• Pressure too low:
• Material slipping through causes an uneven stitch length.
• When moving up, the needle also takes some of the mate-
rial from the presser foot due to friction.
Risk to injury to eyes.
Loosening the regulator too much can cause it
to unscrew and be shot off by the spring under-
neath.
Never unscrew the regulator more than H = 55 mm,
see fig. 24.
