11.2 Service
During normal operation and at the routine inspections verify the air gap and check if all screws are
tight. In case when any symptoms of inefficient braking are observed, then use the self-locking nut
(8) to re-adjust the air gap to the value corresponding to Table 1.
Such readjustment may be repeated until the brake linings are completely worn out. When this will
occur, a complete armature with brake linings (2) must be replaced.
If the air gap of the brake is correctly adjusted and despite of it the brake does not operate properly
(the brake fails to release), it may be caused by:
the electromagnet (1): burned coil or defected output cable (10),
rectifying circuit (installed in the electric motor terminal box).
The above mentioned subassemblies should be checked and defected part replaced.
