D) BELT REPLACEMENT AND ADJUSTMENT
D1) BLADE ROTOR DRIVE BELT
-
Remove the plastic guard, by unscrewing and taking out the screws shown using the
wrench illustrated in fig. 8 pos D
- If the belt ( fig. 9 ref. A) is slack and therefore unable to ensure proper drive to the flail rotor,
move the tightener ( fig. 9, ref. B) from the lower hole ( hole C ) to the upper hole ( hole D).
- If the belt is worn or breaks it should be replaced.
D2) FLAIL ROTOR BELT
-
Remove the plastic guard ( fig. 8 ref.C), by undoing and removing the fixing screws using
the wrench illustrated in 8 ref. D.
-
If the belt ( fig. 9 ref. E) is slack and therefore unable to ensure proper drive to the flail
rotor, move the tightener ( fig. 9, ref. F) from the lower hole ( hole G ) to the upper hole (
hole H).
- If the belt is worn or breaks it should be replaced.
After having made the adjustments as described above, check that flail rotor brake is still
working properly, stopping roller movement immediately.
