Inspect the condition of the serpentine belt (1). Over time the belt ribs will lose material (C). The space between the ribs will increase (D). The loss of material will cause the pulley sheave to contact the belt valley. This will lead to belt slippage and accelerated wear (E). Replace the belt if the belt is worn or frayed.Note: If a new belt is installed, recheck the belt adjustment after 30 minutes of operation.Note: This machine is equipped with a belt tensioner (2). The belt tensioner automatically adjusts the belt to the correct position.
