Before replacement
First release pressure from the pump head.
Stop the pump operation.
Rotate the adjusting screw two revolutions anticlockwise to open
the air vent port.

Do not rotate it three revolutions or more. Otherwise, the adjusting screw may
come off with solution spray.

NOTE
If pressurized liquid is not expelled, run the pump with an opened air vent port
until pressure is removed.
