of the Air Compressor, check for air leaks by
applying soapy water to connections while the
Air Compressor is pumping and after pressure cutout. 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.
10. Open the in-line Shutoff Valve.
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 95 PSI,
and will turn off automatically when the
air pressure reaches 125 PSI.
14. Close the in-line Shutoff Valve.
4. Close the in-line Shutoff Valve between
the compressor and the air hose.
5. Plug the Power Cord into a grounded
