WARNING: RISK OF BURSTING
Air Tank: On February 26, 2002, the U.S. Consumer Product
Safety Commission published Release # 02-108 concerning air
compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life
is dependent upon several factors, some of which include operat-
ing conditions, ambient conditions, proper installations, field modi-
fications, and the level of maintenance. The exact effect of these
factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corro-
sion to the inner wall of the air receiver tank can cause the air tank
to unexpectedly rupture allowing pressurized air to suddenly and
forcefullyescape,posingriskofinjurytoconsumers.
Your compressor air tank must be removed from service by the
end of the year shown on your tank warning label.
The following conditions could lead to a weakening of the air tank,
and result in a violent air tank explosion:

Cut-Out Pressure: When an air compressor is turned on and
begins to run, air pressure in the air tank begins to build. It builds
to a certain high pressure before the motor automatically shuts
off, protecting your air tank from pressure higher than its capacity.
The high pressure at which the motor shuts off is called cut-out
pressure.
Branch Circuit: The circuit carrying electricity from electrical panel
to outlet.
Duty Cycle: This air compressor pump is capable of running
continuously. However, to prolong the life of your air compressor,
it is recommended that a 50%-75% average duty cycle be
maintained; that is, the air compressor pump should not run more
than 30–45 minutes in any given hour.

ADVERTENCIA: RIESGO DE EXPLOSIÓN
Tanque de aire: El 26 de febrero de 2002, la Comisión de
Seguridad para Productos de Consumo delos Estados Unidos
publicó el Comunicado # 02-108 sobre la seguridad en los
tanques de compresores de aire:
Los tanques receptores de los compresores de aire no tienen
una vida útil infinita. La vida útil del tanque depende de diversos
factores, incluyendo las condiciones de operación, las condicio-
nes ambientales, la instalación debida del mismo, modificaciones
realizadas en el campo y el nivel de mantenimiento que reciba.
Es difícil prever cuál será el efecto exacto de estos factores sobre
la vida útil del tanque receptor de aire.
Si no se siguen procedimientos de mantenimiento debidos, la
corrosión interna de la pared interior del tanque receptor de aire
puede causar una ruptura imprevista en el tanque de aire, lo que
hará que el aire presurizado escape con fuerza y repentinamen-
te, pudiendo lesionar al usuario.
