Components
Pressure switch - Auto/Off Switch - In
the "auto" position, the compressor
shuts off automatically when tank
pressure reaches the maximum preset
pressure. In the "off" position, the
compressor will not operate. This switch
should be in the "off" position when
connecting or disconnecting the power
cord from the electrical outlet or when
changing air tools.
Regulator - The regulator controls the
amount of air pressure released at the
hose outlet.
ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.

pressure from tank.
2. Remove existing pressure switch
