d. For variable-speed models only, verify that
V-belts are properly tensioned by applying a
set force to the belt and measuring the
deflection to determine the belt tension. Refer
to Table 6 for the acceptable belt tension
ranges. Belt tension measurements should be
taken as close to the center of the belt span as
possible. Refer to Figure 11.
