CAUTION:
Ensure that the bush is pushed home until it rests against the stop on the motor shaft.
The hub sleeve has a notch (8) that after assembly
must be aligned with the axial slit in the bush (9)
(Photo 6). This check is essential to ensure correct
impeller balance.

3.- Fit the fixing disk (10) of the impeller (Photo 7):
position the two UNTHREADED through holes of
the disk over the threaded in the hub sleeve. Use
the two bolts provided (hub fixing bolts) (11) with
the relative spring washers to fix the bush to the
hub. These bolts must be tightened alternately. It is
essential to tighten them until the tightening torque
indicated in the "Warnings and instructions for use"
manual is reached. When this tightening torque is
reached, check that the disk is not resting against
the impeller sleeve, but is slightly distant from it
(Photo 8).
