STORAGE
Before you store the air compressor, make sure you do the following:
1. Review the "Maintenance" section on the preceding pages and perform
scheduled maintenance as necessary.
2. Set the On/Auto/Off lever to "OFF".
3. Turn the regulator counterclockwise and set the outlet pressure to zero.
4. Remove the air tool or accessory.
5. Pull ring on safety valve allowing air to bleed from the tank until tank
pressure is approximately 20 psi. Release safety valve ring.
6. Drain water from air tank by opening drain valve 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.
7. After the water has been drained, close the drain or drain valve.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, then reinstalled.
8. Wrap electrical cord onto the cord
wrap as shown.
9. Protect the air hose from damage
(such as being stepped on or run over).
10. Store the air compressor in a clean and
dry location.
