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:

How to prevent it

Failure to properly drain condensed

Drain air tank daily or after each use.

 

water from air tank, causing rust

 

If air tank develops a leak, replace

or replace the entire compressor.

 

 

 

 

Modifications or attempted

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 similar to these 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 pre- vent over inflation.
