Operating Instructions

  Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this 

manual including all text under subheadings therein before set up or use of this product.

Compressor Area Set Up

1.  Designate a work area that is clean and well-lit.  

The work area must not allow access by 

children or pets to prevent injury.

2.  Locate the Compressor on a flat level surface to 

ensure proper pump lubrication and to prevent 

damage to the unit.  Keep at least 12

 of space 

around the unit to allow air circulation.

3.  Route the power cord from the compressor 

to the grounded wall outlet, along a safe path 

without creating a tripping hazard or exposing 

the power cord to possible damage.

General Operation

1.  Close the Drain Valve.

2.  Close the in-line Shutoff Valve between 

the compressor and the air hose.

3.  Plug the Power Cord into a grounded 

120 VAC electrical outlet.

4.  Pull the ring on Safety Valve to release pressure.

5.  Turn the Power Switch ON (AUTO) .

6.  Allow the Air Compressor to build 

up pressure until it cycles off.

Note:

 At the beginning of the day’s first use 

of the Air Compressor, check for air leaks by 

applying soapy water to connections while the 

Air Compressor is pumping and after pressure cut-

out.  Look for air bubbles.  If air bubbles are present 

at connections, tighten connections.  Do not use the 

Air Compressor unless all connections are air tight, 

the extra air leaking out will cause the compressor to 

operate too often, increasing wear on the compressor.

Note:

 As long as the Power Switch is ON (AUTO), the 

operation of the Air Compressor is automatic, controlled 

by an internal pressure switch.  The Compressor will 

turn on automatically when the air pressure drops to 135 

PSI, and will turn off automatically when the 

air pressure reaches 175 PSI.   

WARNING! TO PREVENT SERIOUS 

INJURY AND DEATH FROM 

EXPLOSION:

  

Do not adjust the internal 

pressure switch.  

Any change to the 

automatic pressure levels may cause excess pressure to 

accumulate, causing a hazardous situation.

7.  Pull out the Regulator and adjust so that the air 

output is enough to properly power the tool, but 

the output will not exceed the tool’s maximum air 

pressure at any time.  Turn the knob clockwise to 

increase the pressure and counter-clockwise to 

decrease pressure.  Adjust the pressure gradually, 

while checking the air output gauge to set the 

pressure.  Push in Regulator when finished.

8.  Make sure the air tool’s throttle or switch is in the 

off position.  Connect the air tool to the air hose.

9.  Open the in-line Shutoff Valve.

10. Use the air tool as needed.

11.  After the job is complete, turn the Power Switch OFF.

12. Unplug the Air Compressor.

13. Close the in-line Shutoff Valve.

14. Bleed air from the tool then disconnect the tool.

15. Drain Tank according to 

Draining Moisture 

from the Tank on page 12.

16. Clean, then store the Air Compressor indoors.

Emergency Depressurization

If it is necessary to quickly 

depressurize

 the Compressor, turn the Power Switch OFF.  

Then, pull on the ring on the Safety Valve to quickly release stored air pressure.
