Do not interfere with the measurement by snapping the belt with finger during the
measurement.

Before measuring the belt tension, rotate the belt through one complete circuit to re-
move any localized tension risers. When installing a belt, be sure to adjust the tension
to higher than the specification as the belt will stretch over time. After a 24 hour period
has lapsed, measure the tension again and adjust it to the specification.
