8.2.2 Adjusting the brake on the Bearing Unit Friction
(Navigator Lift
(See Figure 11)
For the pendant system Navigator Lift
brakes (friction brakes) keep the extension arm or spring arm in any adjust-
ed position. Adjust the braking force in such a way that the spring arm or
extension arm remain stable in any position and can still be conveniently
adjusted. If the brakes are not adjusted correctly, the extension arm or
spring arm can move automatically in an uncontrolled manner.
NOTE: Adjusting the brakes for the Navigator Lift
Observe the end stop recommendation in Chapter 8.8.3 on page 35 and
make sure that you turn the brake screws of the Bearing Unit Friction on
the ceiling tube tighter than on the bearing point of the spring arm. This fa-
cilitates the bending of the spring arm and allows the bearing unit on the
spring arm to rotate freely. Follow the general safety instructions pre-
scribed in Chapter 8.1 on page 27.

All 3 brake screws must be tightened with the same tightening
torque which, however, must not exceed 1.6 Nm.
