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.
Close the globe valve.
4.
Remove the air tool or accessory.
5.
Open the globe valve and allow the air to slowly bleed from the air tank until
tank pressure is approximately 20 psi.
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.
Protect the air hose from damage (such as being stepped on or run over).
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.
