To Check Safety Valve
If the safety valve does
not work properly, over-
pressurization may occur, causing air tank
rupture or an explosion. Before starting com-
pressor, pull the ring on the safety valve to
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.
To Drain Tank
1. Set the On/Auto/Off lever to “OFF”.
2. Pull the regulator knob out and turn clockwise to
set the outlet pressure to zero.
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 pres-
sure. The valve can then be removed, cleaned, then
reinstalled.
NOTE: See “Operation” section for the location of
controls.
