xing screws on the housing, brakes and traction sheave are marked with locking varnish.
That means a loosened screw is optically visible. If a screw does get turned, it must be tightened
using the prescribed tightening torque, the old locking varnish needs to be removed and marking has
to be made again.
8.2.1
Checking the air gap
1. The airgap has to be measured 4 times at the circumference (see arrows) of both brakes. The
maximum value of the four has to be taken into account.
2. Air gap control areas (1) are indicated by a coloured dot or a machining around the circum-
ference.
3. If the maximum value of the air gap is exceeded on one of the magnets, it must be changed both
brake rotors and the four appendant O-rings.
Maximum admissible air gap after wear: 0.6 mm!
Caution!
Feeler gaugh do not introduce more than 10 mm into the air gap, to avoid damage to the
dampers of noise or deterioration by the springs.
