or replacing parts, relieve the entire
system pressure by opening the air tank
drain/vent valve, which will vent all
pressure to the atmosphere.

SLOWLY (contents under pressure) to
make sure all pressure has been
relieved.
NOTE
This procedure should only be
performed when the compressor is warm
immediately after extended operation.
