VII.  Fixing Leaks

1. If there is a problem with the swivel fitting, then:

a. Check the air line connection by deflating the spring and removing the line by pulling the collar against the fitting

and pulling firmly on the air line.  Trim 1" off the end of the air line.  Be sure the cut is clean and square.  Reinsert
the air line into the push-to-connect fitting.

b. Check the threaded connection by tightening the swivel fitting another

 turn.  If it still leaks, deflate the air

spring, remove the fitting, and re-coat the threads with thread sealant.  Reinstall by hand tightening as much as
possible, then use a wrench for an additional two turns.

2. If there is a problem with the inflation valve, then:

a. Check the valve core by tightening it with a valve core tool.

b. Check the air line connection by removing the air line from the barbed type fitting.  

CAUTION:  Do not cut it off.

As this will usually nick the barb and render the fitting useless.  Cut air line off a few inches in front of the fitting
and use a pair of pliers or vise-grips to pull/twist the air line off the fitting.

3. If the preceding steps have not resolved the problem, call Air Lift Technical Service at 1-800-248-0892 for assistance.

VIII.  Troubleshooting Guide

Problems maintaining air pressure, without on-board compressor.

1. Leak test the air line connections and threaded connection of the elbow into the air spring.  See Section VII to

repair.

2. Leak test the inflation valve for leaks at the air line connection or dirt or debris in the valve core.  See Section VII for

repair.

3. Inspect air lines to be sure it is not pinched.  Tie straps may be too tight.  Loosen or replace strap.  Replace leaking

components.

4. Inspect air line for holes and cracks.  Replace as needed.

5. A kink or fold in the air line.  Reroute as needed.

You have now tested for all of the most probable leak conditions that can be easily fixed.  At this point the problem is
most likely a failed air spring - either a factory defect or an operating problem.  Please call Air Lift at 1-800-248-0892 for
assistance or a replacement air spring.
