1. Inspect belt for cracks, cuts, deformation, wear and cleanliness.
2. Check belt for tension. Belt is in proper tension when it deflects 6 to 8 mm (0.24 - 0.32 inch) under thumb pressure (about 10 kg or 22 lb.).
Belt tension "a":
6 - 8 mm (0.24 - 0.32 inch) (G16 engine)
9 - 11 mm (035 - 0.43 inch) (H-25 engine)
as deflection/10 kg (22 lbs)
NOTE: When replacing belt with a new one, adjust belt tension to 5 - 7 mm (0.20 - 0.27 inch) (G16 engine) or 7 - 9 mm (0.27 - 0.35 inch) (H-25 engine).
3. If belt is too tight or too loose, adjust it to proper tension by displacing generator position.
