Clean the contact surfaces of the insert shaft (2)
(inside) and the motor shaft (3). They must not
be lubricated or oiled.
7) Set the motor down on the fan cover.
8) Position the shaft clamp (1) (use a new shaft
clamp) in the centre of the cranked clamping di-
ameter (2) of the insert shaft.

shaft (2).
10) Tighten:
Mark the first screw and tighten all the screws
evenly by hand, one after the other in a clock-
wise direction (not cross-ways).
Use a torque screwdriver to tighten each screw
first with 2 Nm then with 3.5 Nm and finally with
5 Nm (in a clockwise direction again).
