What should you do with the air lines after disconnecting them from the trailer?
- A.Connect them to dummy couplers or together, and hang them so they cannot be damaged or collect dirt
- B.Let them hang to the ground
- C.Leave the ends open on the catwalk
- D.Wrap them around the exhaust stack
Correct answer
A. Connect them to dummy couplers or together, and hang them so they cannot be damaged or collect dirt
Why
Open gladhand ends collect dirt and moisture that later enter the air system, and dangling hoses can be torn off. Dummy couplers keep the system clean and the lines safe.
