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

valveremains closed. On the upstroke of the piston,air is
compressed. The intake valves close and compressed
air is forced out through the exhaust valve and then
through the air hose.
Adjustable Pressure Valve Knob: The pressure valve
knobcontrols the amount of pressure going from the air
compressor tothe accessory, Pressure can be set at any
point between 10and 100 RS,I. (100 P.S.I.isthe highest
pressure this compressor will deliver,) Always set the
pressure valve knob at or below the required pressure for
the accessory being used, THE ADJUSTABLE PRES-
