8.6 Fan bearing lubrication
Bearings are properly sized, with double sealed protection (2RS) and lubricated for life, therefore they do not
require any additional lubrication.
8.7 Propeller replacement
If damage occurs to the propeller,
it is necessary to replace the whole
propeller because of the difficulty to
balance it in the field. How to replace
the propeller:
1. remove the pyramidal safety mesh
and unscrew the four M8 bolts
holding the propeller to the fan;
2. remove the propeller;
3. insert the new propeller;
4. tighten the four M8 bolts holding
the propeller to the fan and re-
install the pyramidal safety mesh.
