cycles automatically when power is
on. When performing maintenance,
you may be exposed to voltage
sources, compressed air, or
moving parts. Personal injuries can
occur. Before performing any
maintenance or repair, disconnect
power source from the compressor
and bleed off all air pressure.

NOTE: See "Operation" section for the location of controls.

5.Place suitable container under unit to catch water.

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, contact a trained service technician.

To Drain Tank

NOTICE: Allow unit to cool before draining tank, drain valve becomes hot during operation.

1.Set the Off/Auto switch to "OFF".

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

3.Pull and hold ring on safety valve allowing air to bleed from the tank until air pressure is minimized.

6.Slightly tilt unit and turn drain valve counter clockwise to open.

7.Place unit back onto blocks to drain water from air tank.

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.

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