Air Compressor Pump: To compress air, the piston
moves up and down in the cylinder. On the downstroke,

air is forced out through the exhaust valve and then
through the air hose.
Adjustable Pressure Valve Knob: The pressure valve
knob controls the amount of pressure going from the air
compressor to the accessory, Pressure can be set at any
point between 10 and 100 RS,I. (100 P.S.I. is the highest
pressure this compressor will deliver,) Always set the
pressure valve knob at or below the required pressure for
