Place the complete assembly you have obtained on
the fan, inserting the axle throught the central support
hole.
Place the nut (ref.7.10/Bolts&nuts) on the axle and
then tighten it by mean of pneumatic screwdriver

Check tensioning: right tensioning is obtained when
maximum deflexion on one side only (half-way from
motor and central pulley) is about 15 mm.
