Condition of Belts
BNUUUM02.C07 0000274604 A.4 A.2 2/4/20 8:08 AM Released
Slippage when the pulley turns more quickly than the belt can move
Slippage occurs if belts are not aligned (see Section ) or by incorrect tension explained in Section
. Slippage can cause belts to become too hot. Belts must not have a temperature more than than
140F (60° C).
TIP: The belt storage area must be cool and dry with no sun light.
TIP: New and used belts can look the same. These belts will have different strength
properties and a small difference in length.
