7. Reassemble the blade connection belt (12)
and the pulley (11).
8. Before tightening the four screws (9), tense
the belt, which is done by moving the left sup-
port sideways. There are two ways to do this:
• Option A
– Tighten the belt by pulling the left-hand
bearing bracket with a force of 300 N (30
kg), then tighten the four screws (9) of the
bearing bracket.
• Option B
– Tighten the belt by pulling on the left-hand
bearing bracket and tighten the four screws
(9) of the bearing bracket.
– Apply a force of 35 N (3.5 kg) to the centre of
the belt. The belt will flex 10 mm. Otherwise,
loosen the screws (9) and repeat the opera-
tion until the correct result is obtained.
9. Complete the assembly by following steps 1 -
4 described above backwards.
10. Verify that the blades orientation meets the correct synchronization parameters indicated in
the "Synchronizing the blades" procedure.
