Oil and moisture residue must be drained from the air receiver daily or after each use.
Accumulations of oil residue in the receiver can be ignited by embers of carbon created
by the heat of compression - causing an explosion, damage to property and injury to
personnel.
Do not open a manual tank drain valve on any air tank containing more than 30 PSIG of air
pressure!
Never attempt to relieve an air tank by removing a pipe plug or any other system
component!

Manually Draining an Air Tank:
Step 1).
Disconnect and lockout the compressor from the power source (electric models) or disconnect

Step 2).
Tank(s) subjected to freezing temperatures may contain ice. Store the compressor in a heated
area before attempting to drain moisture from the tank(s). Reduce the air pressure in the tank
to 30 PSIG by pulling the pressure relief valve ring.
Step 3). Slowly open the drain valve and allow the moisture and air mixture to drain from the tank.
Step 4).
Once the moisture has been completely drained, close the drain valve.
