clip the gauge onto the belt edge. Then use your fingers to rotate the outer gauge dial
to fine adjust the needle to precisely 3.0 (0.0%).

key belt tension adjustment bolts to the point where the belt tension just starts
to exceed 3.0 (0 % ref) for each gauge. Do not exceed 3.0 (0 %) reference.
b. At this point the tension pressure has increased significantly and care must be
