TO DRAIN TANK
Risk of Unsafe Operation. Risk from noise. Air tanks contain
high pressure air. Keep face and other body parts away from outlet of drain.
Use ANSI Z87.1 eye protection (CAN/CSA Z94.3) when draining as debris
can be kicked up into face. Use ear protection [(ANSI S12.6 (S3.19) hearing
protection] as air flow noise is loud when draining.
1. SettheOn/Offswitchto"Off".
2. Turn the regulator knob counter-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 on bottom of tank.
Risk of Bursting. 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.
Risk of Property Damage. Drain water from air tank may con-
tain oil and rust which can cause stains.
6. Afterthewaterhasbeendrained,closethedrainvalve.Theaircompressor
can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, the reinstalled.
