Example text

If the air valve should suddenly close, hands or fingers could be injured or lost. Pressurized air can also be trapped between the shutoff valve and the air valve; therefore, any removal of air valve bolts, plugs, or covers must be done with extreme care to release trapped air slowly and prevent serious injury.
