d. For variable-speed models only, verify that V-belts are properly tensioned by applying a set force to the belts and measuring the deflection to determine the belt tension. Refer to Table 3 for the acceptable belt’s tension ranges. Belt tension measurements should be taken as close to the center of the belt span as possible. Refer to Figure 16.
