Check Fan/Alternator Belt Tension
Check belt tension every 50 hours. Belt is properly tensioned when it moves about 3/8” (10 mm) when
pushed at the long span (4). To adjust belt, move tensioner pulley:
1. Loosen socket bolt (2) and bolt (1).
2. Use a prybar in slots (3) to move pulley.
3. Tighten socket bolt (2) and bolt (1).
4. Check belt tension and adjust as needed.
Change Hydraulic Fluid Filter (initial)
Change hydraulic fluid filter for the first time at 50 hours and every 500 hours thereafter.
Note: Boltheads are hidden. Use an 8 mm hex wrench, a 17 mm open end wrench, and a 1/2” prybar for
this procedure.
