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 Air Compressor Power Cord into
a grounded 120 V~ electrical outlet.
4. Turn the Power Switch ON.
5. 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, 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 125 PSI,
and will turn off automatically when the
air pressure reaches 150 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.
6. Adjust the Regulator Knob 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.
7. Make sure the air tool’s throttle or switch is in the
off position. Connect the air tool to the air hose.
8. Open the in-line Shutoff Valve.
9. Use the air tool as needed.
10. After the job is complete, turn the Power Switch OFF.
11. Unplug the Air Compressor.
12. Close the in-line Shutoff Valve.
13. Bleed air from the tool then disconnect the tool.
14. Turn the Drain Valve, at the bottom of the Tank,
two turns to release any built-up moisture and the
internal tank pressure. Close the valve after moisture
has drained out. Do not remove the Drain Valve.
15. 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.
