PTO Belt Inspection Inspecting the PTO belt of this power unit can prevent sudden belt failure by finding problems before they cause a belt to break. Inspect the PTO belt prior to operation, as part of the daily inspection or anytime a problem is suspected. There may be a PTO belt prob- lem if there is a squealing or chattering sound, or the smell of a slipping belt. Check the PTO belt (A) at the PTO idler pulley (B).

Loosen the adjustment bolt (A) and rotate the ten - sion adjustment link (B) clockwise to increase the tension applied to the PTO and attachment belts. Rotate the tension adjustment link counterclock- wise to decrease the tension applied to the PTO and attachment belts.
