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. 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).
