1 Complete stator 31 Adjuster nut
1. Turn the adjuster nut (31) counterclockwise using the hook wrench.
– Observe the notches. Positions between notches are impermissible. (Values for the
brake torque reduction see chapter 3.2.1).
– The maximum permissible projection ”h
Emax.
” of the adjuster nut (8) to the stator (1)
is to be observed (values for ”h
Emax.
” see chapter 3.2).
Danger!
The reduction of the brake torque does not increase the maximum permissible
air gap ”s
Lmax.
”.
Do not change the manual release setting for models with manual release.
