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" and unplug unit.
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.
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.
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, and 
reinstalled.
8. Protect the electrical cord and
air hose from damage (such as 
being stepped on or run over). 
Wind them loosely around 
the compressor handle. (If so 
equipped)
9. Store the air compressor in a
clean and dry location.
