Installation Guide
Mark the center of the span. At the center mark, use
a tension tester and apply a force perpendicular to
the span large enough to deflect the belt 1/64 inch
for every inch of span length (example: a 100 inch
span requires a deflection of 100/64 inch or
1_⁄{| inches).
Compare the actual deflection force with the values
in Tables 5, 6 and 7 (at right and page 14). A force
below the target value indicates under-tension.
A force above the target indicates over-tension.
