Getting to Know Your Air Compressor (Continued)
1 . Air Outlet fittings . These fittings are 1/4 inch
universal-style quick connect fittings and allow rapid
tool changes.
2 . Regulated Outlet Gauge . This gauge shows
at-a-glance, air pressure at outlet. Air pressure is
measured in pounds per square inch (PSI). Most
tools have maximum pressure ratings. Never exceed
the maximum pressure rating of the tool you are
using. Be sure this gauge reads ZERO before
changing air tools or disconnecting hose from outlet.
3 . Handle . Used to move the compressor.
4 . Regulator Knob . This knob controls air pressure to
an air operated tool or paint spray gun. Turning the
knob clockwise increases air pressure at the outlet.
Turning counterclockwise will lower air pressure at
the outlet. Fully counterclockwise will shut off the
flow of air completely.

5 . Tank Pressure Gauge . Gauge shows pressure in
tank indicating compressor is building pressure
properly.
6 . Pump . The pump takes in air and generates the
pressurized air in the air storage tanks.
7 . ASME Safety Valve . This valve automatically
releases air if the tank pressure exceeds the preset
maximum.
8 . On/Off Switch . This switch allows manual control of
OPEN
the compressor. Note that when the switch is turned
on, the compressor will automatically start and stop
depending on tank pressure.
9 . Tank Drain Valve . The tank drain valve allows
moisture to be removed from the tanks.
10 . Air Storage Tanks . The tanks store air for later use.
