BALL ACCELERATOR FLAT BELT ADJUSTMENT
Flat Belt Tension
A large tension spring at the front of the accelerator provides the tension for the at belt. When the belt
is under proper tension, this spring will be approximately 185 mm from spring hook to spring hook.
Refer to Figure 4-12. Adjust by tightening or loosening the two tensioning nuts that secure the long
tension bar to the rear of the accelerator frame.
