CAUTION
The belt tensioner is spring-loaded and must be
pivoted away from the drive belt. Pivoting in the
wrong direction can result in damage to the belt
tensioner.
Pivot the tensioner to relieve tension in the belt, and
remove the belt.
NOTE: The belt tensioner winds in the direction that the
spring tang is bent over the tensioner body. To loosen the
tension on the belt, rotate the tensioner to wind the spring
tighter.
CAUTION
Applying excessive force in the opposite direction of
windup or after the tensioner has been wound up to
the positive stop can cause the tensioner arm to
crack or break.
