To Check Safety Valve

If the safety valve does not work properly, over-

pressurization may occur, causing air tank rupture or an explosion. Before starting com- pressor, 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.Pull the regulator knob out and turn 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) on bottom of tank.

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 pres- sure. The valve can then be removed, cleaned, then reinstalled.
