To increase pressure, push down the pressure
regulator button until suitable pressure is obtained.
To release pressure, push down the ring, then
the button will spring up to its highest position.
The top of button should normally be pushed down to about 3/ 4 position from its highest position,
except for the following:
●
Set the top of button at 1/4 position from its highest position for sewing delicate synthetic fabrics
and knitted fabrics which tend to stretch out of shape.
●
Set the top of button at the depressed position to the bottom for thick and heavier fabrics.
