8.5.7.1 Checking the swich-off buffer / switch-off spring
Fig. 62
1. Buffer wear:
In the course of annual inspection visually check the buffers. Check for damage and cracks.
2. Missing buffer plate:
When fitting new buffers, pay attention to the correct fitting sequence of the component parts ( see also
⇒ "Buffer design", Page 92), e.g. a missing buffer plate leads to premature wear of the buffers.
3. Wear of external switch-off spring:
In the course of annual inspection visually check the external switch-off springs. Check the sleeves of the
springs for damage and cracks. The individual windings of the springs must not be shifted above each other.
