Figure 3. Air output components.

G.  Quick-Connect Port: Secures and releases 

air hose when pressed in. 

H.  Regulator Knob:  Adjusts  pressure  of  air 

delivered to quick-connect ports. Turn clock-
wise to increase pressure and counterclock-
wise to decrease pressure.

I.  Line Pressure Gauge: Indicates pressure of 

air at quick-connect ports.

Air Output/Delivery

J.  Pressure Switch Lever:  Toggles  pressure 

switch  between  OFF  and  AUTO  modes. 
Machine is 

OFF in OFF mode, and will con-

tinue to pressurize when in AUTO mode.

K.  Discharge Line: Releases air from compres-

sor pump and outlet line when tank pressure 
exceeds 125 PSI (cut-out pressure).

L.  Safety Relief Valve:  Pops  open  to  release 

tank  pressure  in  the  event  that  pressure 
switch fails to stop motor at cut-out pressure.

M.  Pressure Switch:  Turns  motor  ON  when 

tank  pressure  drops  below  95  PSI  (cut-in 
pressure)  and  switch  is  in  AUTO  position. 
Switch contains pressure relief valve that will 
activate  discharge  line  when  tank  pressure 
exceeds 125 PSI (cut-out pressure) or pres-
sure switch is turned 

OFF.

motor when pressed after overload. To reset, 
place pressure switch lever in OFF position, 
wait  a  few  minutes  for  motor  to  cool,  then 
press  motor  reset  button.  If  motor  does  not
