Fig. 27. Regulating the Pressure on the Material
The correct presser foot pressure helps feed the work
properly. You can regulate the amount of pressure by
means of the thumb screw, as shown in
Fig. 27.
The pressure on the material should be as
light
as
possible, while still sufficient to insure proper feeding.
To increase the pressure turn the thumb screw down
ward
(clockwise).
To
reduce
the
pressure
turn
this
screw
upward

and
smoothly
without stalling.
