HAZARD
RISK OF BURSTING
Air Tank: The air tank on your compressor is designed and may be UM coded [for
units with air tanks greater than 6" (152.4 mm) diameter] according to ASME Section
VIII, Div. 1 rules. All pressure vessels should be inspected once every two years.
To find your state pressure vessels inspector, look under the Division of Labor and
Industries in the government section of a phone book .
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modifica-
tions to the safety valve or
any other components which
control air tank pressure.
• Theairtankisdesignedtowith-
stand specific operating pres-
sures. Never make adjustments
or parts substitutions to alter the
factory set operating pressures.
• Excessivevibrationcanweakenthe
air tank of a stationary compressor
and cause an explosion.
• The compressor must be properly
mounted, see Anchoring under
Installation.
Attachments & accessories:
• Exceedingthepressurerat-
ing 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 simi-
lar 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.
