IMPORTANT:
Air pressure in the tank
must be 2 psi lower than the “cut-in” of
the pressure switch. Pump/tank (A) has a
20/40 psi pressure switch, so tank pressure
must be set at 18 psi. Locate the air valve/
stem on the tank and check pressure with
a tire gauge (not included). If air needs to
be removed, press down on valve to bleed
air off. Use a tire pump or air compressor to
add air if needed.
