DRIVING BELT TENSION.
Each belt should be tight enough to drive without undue strain on bearings. Using moderate finger pressure at the points indicated in the illustrations
each belt should not deflect more than 0.19 to 0.25 in (4 to 6 mm). Deflection beyond this limit indicates belt looseness which may cause a loud whining
or knocking noise in operation and intermittent drive.
