Enclosed is short video demonstrating the fine tuning with the 2 axis tracking mechanism. The belt was purposely setup to be running into the grinder to demonstrate how the new mechanism works. First set the tracking wheel so that it is level horizontally . Place a belt onto the grinder and move the belt by hand. Adjusting the two socket cap screws allows the belt to be moved to the left or right. Once you have it dialed in, tighten the two screws. Turn the grinder on and repeat this step if necessary. This tracking mechanism allows you to adjust the tracking wheel in two different planes which makes setup so much easier. See the detailed instruction that are sent with each grinder.
The 2 axis tracking mechanism is installed on all of the Nexus Grinders.
