OPERATION
DRAINING THE TANKS
See Figure 12.
To help prevent tank corrosion and keep moisture out of the air used, the air tanks of the compressor should be drained daily.
NOTE: The air compressor has two separate tanks: an upper tank and a lower tank. Be sure to open drain valves for both and perform this operation for both tanks.
To drain:
nRotate drain valves counterclockwise to open.
nDrain moisture from tanks into a suitable container.
NOTE: Condensate is a polluting material and should be disposed of in compliance with local regulations.
nIf drain valves are clogged, release all air pressure, remove and clean valves, then reinstall.
WARNING:
Unplug the air compressor and release all air from the tanks before servicing. Failure to depressurize tanks before attempting to remove valve may cause serious personal injury.
nRotate drain valves clockwise until tightly closed.
CHECKING THE SAFETY VALVE
See Figure 13.
DANGER:
Do not attempt to tamper with the safety valve. Anything loosened from this device could fly up and hit you. Failure to heed this warning could result in death or serious personal injury.
The safety valve will automatically release air if the air re- ceiver pressure exceeds the preset maximum. The valve should be checked before each day of use by pulling the ring by hand.
nTurn the air compressor on and allow the tanks to fill. The compressor will shut off when the pressure reaches the preset maximum.
nTurn the air compressor off.
nPull the ring on the safety valve to release air for three to five seconds.
nRelease the ring. Air must immediately stop escaping when the ring is released. Any continued loss of air after releasing the safety valve ring indicates a problem with the safety valve. Discontinue use and seek service before continued use of the air compressor.

WARNING:
If air leaks after the ring has been released, or if the valve is stuck and cannot be actuated by the ring, Do not use the air compressor until the safety valve has been replaced. Use of the air compressor in this condition could result in serious personal injury.
