c. For flat-pulley drive systems, verify allowable
distance of belt from edge of pulley as shown
in Table 6 below:
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 7 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.

NOTE: Hoses and other natural rubber parts
deteriorate after extended use. Hoses may develop
cracks, blisters or material wear from the
temperature and constant high pressure they are
subjected to.
2. Check all hoses for any visible signs of
deterioration. Any hose showing signs of
deterioration listed above should be replaced
immediately.
NOTE: All hoses should be replaced every five
years.
