D) BELT REPLACEMENT AND ADJUSTMENT
If a belt breaks or becomes worn it is advisable to change both belts connected to the engine
at the same time. The replacement of just one belt alone may give rise to adjustment problems.
Conversely, the blade rotor control belt is completely independent of the others, so for its
replacement or adjustment carry out the following:
WARNING
ANY COMPLEX JOB AND ANY WORK AFFECTING THE SAFETY OF THE
OPERATOR AND/OR OTHER PERSONS MAY ONLY BE CARRIED OUT AT AN
AUTHORISED SERVICE CENTRE
D1) BLADE ROTOR DRIVE BELT
- remove the guard ( Fig. 9 Ref. C), by unscrewing and taking out the screws shown in
Figure 9 Ref. B
- pull the spring ( Ref. A Fig. 10 ) off the upper connecting screw ( Fig. 10 Ref. B) , so that
the belt tightener ( Ref. C Fig. 10 ) remains free and lowers automatically.
- slip the belt off by turning the lower pulley in an anti-clockwise direction using your hand
(Ref. D Fig. 10).
-
obviously for assembly the procedure must be reversed, bearing in mind that once the
spring is in position the belt is automatically in its ideal adjustment position.
