1. TESTING FOR EXCESSIVE WEAR
Option 1: Connect an API-LI to the LYNX series coupler. Please consult Liquip for more info on the API-LI.
Option 2: Connect the coupler to a new API vehicle adaptor. With the vehicle adaptor clamped securely in a vice try to
rock the coupling in relation to the vehicle adaptor. Be sure to rock the coupler about the axis which it would normally
receive the most wear and tear. If there is any more than 5mm lateral movement at the back end of the coupler it is
worn out and unserviceable.
