5. Perform at least three functional tests by actuating
the lever (9) on the lever block (1) until the brakes are
released. (Make a visual check of the brake air gap; check
that the traction sheave can turn freely.)
A force of ca. 260 N should be required to release the
brakes with a lever length of 0.5 m (if 3 partial brakes are
provided). Check the installation if greater force than this
is required.

Warning:
More excessive force (> 300 N with a 0.5 m lever
length) is unacceptable, as it can damage the brakes beyond
repair.
Set the lever (9) back to its rest position once the test is
completed (check the air gap with the traction sheave
locked).
Ensure that the manual release levers (4) on the individual
partial brakes are back to their initial positions.

7. Restrict the movement of the lever (9) using the disc (14)
to prevent it from being pulled further (with a tolerance of
approx. +3°).
To this end, lock the disc (14) on the threaded rod (12) in
the appropriate position by tightening the lock nuts (13
and 15).
