To reset the correct tension:
1. with the propeller at a complete standstill, open the
safety mesh guard on the pulley/motor side;
2. loosen motor slide fixing screws;
3. tighten the V-belt by pushing the motor sideways;
4. tighten the fixing screws adequately;
5. fix the safety meshes guard to the fan housing.
WARNING
Do not operate the fan with the safety protections removed: safety meshes can be removed only
with specific tools by qualified technicians when the fan reaches a complete standstill.
The fixing systems of the safety protections are not interchangeable with other devices. Therefore, if for
maintenance reasons the user damages or loses any component, this must be definitely ordered from the manufacturer
as spare parts and it cannot just be replaced with other components, even similar, not supplied by the constructor itself. In
this particular event the manufacturer refuses all responsibility on consequent damages caused to things and people and
considers any kind of warranty lost.
8.4 Replacement of propeller
If propeller damaging occurs, it is necessary to substitute the whole propeller because of the difficulty to balance it, in the
field.
