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 modifications, 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 corrosion 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:

WHAT CAN HAPPEN

HOW TO PREVENT IT

•  Failure to properly drain condensed water 

from air tank, causing rust and thinning of 

the steel air tank.

•  Drain  air  tank  daily  or  after  each  use. 

If air tank develops a leak, replace it 

immediately with a new air tank or 

replace the entire compressor.

•  Modifications or attempted repairs to the 

air tank.

•  Never  drill  into,  weld,  or  make  any 

modifications to the air tank or its 

attachments. Never attempt to repair a 

damaged or leaking air tank. Replace 

with a new air tank.

•  Unauthorized modifications to the safety 

valve or any other components which 

control air tank pressure.

•  The  air  tank  is  designed  to  withstand 

specific operating pressures. Never make 

adjustments or parts substitutions to 

alter the factory set operating pressures.

Attachments & accessories:

•  Exceeding the pressure rating of air tools, 

spray guns, air operated accessories, 

tires, and other inflatables can cause 

them to explode or fly apart, and could 

result in serious injury.

•  Follow  the  equipment  manufacturers 

recommendation and never exceed the 

maximum allowable pressure rating of 

attachments. Never use compressor to 

inflate small low pressure objects such 

as children’s toys, footballs, basketballs, 

etc.

Tires:

•  Over  inflation  of  tires  could  result  in 

serious injury and property damage.

•  Use  a  tire  pressure  gauge  to  check  the 

tires pressure before each use and while 

inflating tires; see the tire sidewall for the 

correct tire pressure. 

 

NOTE:

 Air tanks, compressors and similar 

equipment used to inflate tires can fill 

small tires very rapidly. Adjust pressure 

regulator on air supply to no more than 

the rating of the tire pressure. Add air in 

small increments and frequently use the 

tire gauge to prevent over inflation.

HAZARD

 

RISK OF ELECTRICAL SHOCK

CFM: 

Cubic feet per minute.

SCFM: 

Standard cubic feet per minute; a unit of measure of air delivery.

PSIG:

 Pounds per square inch gauge; a unit of measure of pressure.

Code Certification: 

Products that bear one or more of the following marks: UL

®

, CUL, 

CULUS, ETL

®

, CETL, CETLUS, 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  as  you  continue  to  use 

your accessory. When the tank pressure drops to a certain lower 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 automati-

cally shuts off, protecting your air tank from pressure higher than its capacity. The high pres-

sure at which the motor shuts off is called "cut-out" pressure.

Branch Circuit: 

Circuit carrying electricity from electrical panel to outlet.
