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 operating
conditions, ambient conditions, proper installations, field modifica-
tions, and the level of maintenance. The exact effect of these fac-
tors 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:

the factory set cut-in pressure. It stops the motor when the air tank
pressure reaches the factory set cut-out pressure.
SAFETY VALVE
If the pressure switch does not shut off the air
G
F
compressor at its cut-out pressure setting, the
safety valve (G) will protect against high
pressure by popping out at its factory set
pressure (slightly higher than the pressure
switch cut-out setting).
CHECK VALVE
When the air compressor is operating, the
check valve (F) is open, allowing compressed air to enter the air
tank. When the air compressor reaches cut-out pressure, the check
valve closes, allowing air pressure to remain inside the air tank.

CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSI: Pounds per square inch; a unit of measure of pressure.
Code Certification: Products that bear one or more of the following marks: UL

*, CUL, ETL
®
*, CETL, have been evaluated by OSHA
certified independent safety laboratories and meet the applicable Standards for Safety.

Cut-In Pressure: While the motor is off, air tank pressure drops when accessory is used. When the tank pressure drops to a certain low
level the motor will restart automatically. The low pressure at which the motor automatically restarts is called cut-in pressure.
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.
