Understanding the Model 90 Series ECO
BALANCED INFLATION

First of all, the ECO does not produce air, it only meters it.  So many people over the years have asked me, where is the compressor.

It operates by air pressure, not by electricity.  When you lift the hose from the hook it opens the mechanism allowing the air to circulate.  Once the chuck is placed on the valve stem of the tire, a shot of air is sent into the tire.  It then stops and reads the pressure of the tire to see if it the same as what the setting is.  If it is not the same, another shot of air is sent into the tire.  Each time it does this, the bell rings.  It works like this: SHOT....READ....SHOT....READ....SHOT....  It will continue to do this until the pressure in the tire is the same as the pressure that was set on the mechanism.  This is what the words "BALANCE INFLATION" on the top chrome piece means.

If it does or doesn't do what it is supposed to do, you now need to repair it, my first suggestion is to get a one of my Service Manuals.  If you want us to repair it CLICK HERE
