PRE-START CHECKLIST:
1. Check oil level. Add if necessary.
2. Remove any moisture in the air compressor air tank. NEVER attempt
to open the Air Tank Drain Valve when more than 10 PSI of air
pressure is in the air tank! Remove excessive pressure with an air
tool, then open the Air Tank Drain Valve in the bottom of the air tank.
Close tightly when drained.
3. Make sure the Motor/Pressure Switch is in the "OFF" position.
4. Make sure the Safety Relief Valve is working correctly.
5. Make sure all guards and covers are in place and securely mounted.
START-UP:
1. Read safety warnings before performing operation.
2. Ensure the Motor/Pressure Switch is in the "OFF" position.
3. Plug the Power Cord into a grounded outlet.
4. Move the Motor/Pressure Switch to the "AUTO" position.
FOR UNITS EQUIPPED WITH DUAL CONTROL: Locate the adjustment
knob at the top of the Pilot Valve.
- Turn it completely clockwise to the fully closed position. This will
allow the air compressor to start building up pressure in the air tanks
and shut-off when correct pressure is achieved. When pressure
drops with usage, the air compressor will start automatically.
- Turn it completely counterclockwise to the fully open position. The
air compressor is now set up to run continuously. When pressure
reaches the preset level in the air tank, pressure will bleed through
the Pilot Valve with the motor still running.
5. Set pressure by adjusting the Pressure Regulator counterclockwise for
less pressure and clockwise for more pressure.
6. If you notice any unusual noise or vibration, stop the air compressor
and refer to "Troubleshooting".
SHUTDOWN:
1. To stop the air compressor, move the lever on the pressure switch
box to the "OFF" position, then unplug the unit from the electric
circuit. NEVER stop the air compressor by unplugging it from the power
source. This could result in risk of electrocution or damage to unit.
2. Drain air from the air tanks by releasing air with an attached air tool or by pulling
on the Safety Relief Valve.
3. Once the Air Tank Pressure Gauge registers under 10 pounds, open the Air Tank
Drain Valve under each air tank to drain any moisture.
4. Allow the air compressor to cool down.
5. Wipe the air compressor clean and store in a safe, non-freezing area with the
cord coiled up and protected from accidental damage.
