J. TENSION OR REPLACEMENT OF THE TRANSMISION BELTS.
The transmission belts (C, Fig.10) should be checked after some time and then should be adjusted if necessary.
Check frequently the belt tension and place finger pressure on the top of the belt. The belt should deflect around 8 mm.
Normal wear of the transmission belts can also mean that they should be replaced.
To check the belt tension, remove the belt guard (P, Fig.10) loosening the screws (T, Fig.10) and adjust them
or replace them.
If the belt tension requires adjustment, adjust the engine's position backwards loosening the nuts (A, Fig.10)
and tighten the screw (R, Fig.10). Once set, tighten again the nuts of the engine.
If the belt tension needs replacement, adjust the engine's position forward and loosen the nuts and screw R. Then
remove them and replace them. After, adjust again the engine until you reach a correct tension for the belts. Tighten again
the nuts of the engine.
Whenever you remove the belt guard P, check the pulley alignment between the engine pulley and the blade
pulley. Take a ruler, place it and check that there is no room left between.
