5. Fine tune the belt tension with the adjustment bolts so that you
can push in the belt approximately 1/2-inch on one side.
6. Activate the self-calibration feature as instructed in chapter 3,
“Maintenance.”
Tracking Adjustments
The motor is mounted at a very slight angle so that the belt meshes
quietly with the sprockets. Because of this design, the belt will always
track to one side of the top sprocket. However, you may have to make
slight adjustments to the top sprocket’s 3/32-inch Allen screws to align
the top sprocket with the lower sprocket so the belt tracks evenly on the
lower sprocket.
NOTE
Excessive tension will cause undue stress
on the motor shaft.
