3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing air to bleed from
the tank until tank pressure is approximately 20
psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve
(counter-clockwise) 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.
6. After the water has been drained, close the drain
valve (clockwise). The air compressor can now
be stored.
NOTE: If drain valve is plugged, release all air pressure.
The valve can then be removed, cleaned, then rein-
stalled.

If the safety valve does
not work properly, over-
pressurization may occur, causing air tank
rupture or an explosion. Before starting com-

make sure that the safety valve operates
freely. If the valve is stuck or does not operate
smoothly, it must be replaced with the same
type of valve.
