Risk of Unsafe

Operation. Unit

cycles automatically when power is on. When servicing, you may be exposed to voltage sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool.

NOTE: See Operation section for the location of controls.

To Check Safety Valve

Risk of Bursting. If the safety valve

does not work properly, over- pressurization may occur, causing air tank rupture or an explosion.

1.Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve

is stuck or does not operate smoothly, it must be replaced with the same type of valve.

To Drain Tank

1.Set the On/Auto/Off lever to "Off".

2.Turn the regulator knob counter- clockwise to set the outlet pressure to zero.

3.Remove the air tool or accessory.

4.Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring.

5.Drain water from air tank by opening drain valve (counter- clockwise.

Risk of Bursting. Water will

condense in the air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture.

6.After the water has been drained, close the drain valve (clockwise). The air compressor can now be stored

NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, the reinstalled.
