Hold the Manual Breast Pump to your
breast so that your nipple is centered

counter-clockwise to decrease it.

If an adjustment is necessary,
turn the round knob of the Adjusting
Valve to a comfortable suction level.

Note:
Do not over-turn the Adjusting Valve, as it will cause the Adjusting Valve
to bulge and leak air, creating a suction problem. Make sure the gap opening on
top of the Adjusting Valve is lined up properly on the top of the Valve Stem so the
Adjusting Valve turns smoothly.
If necessary, re-adjust the Adjusting Valve by turning it back and forth a few times.
