Unit 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.
TO CHECK SAFETY VALVE
If the safety valve does not work
properly,
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 counterclockwise 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. The air compressor can now be stored.
NOTE: If drain valve is plugged in, release all air pressure. The valve can then be removed, cleaned, and reinstalled.
