6. Start the engine and run it at idle speed, then allow the stone to resurface the collector ring.

2
00:00:07,458 --> 00:00:13,958
<b>Note: </b>When the stone wears down to a very small portion, it will crumble and fall out of the brush assembly.

3
00:00:13,958 --> 00:00:19,042
7. Shut down the engine and re-inspect the collector rings.

4
00:00:19,042 --> 00:00:26,875
<b>Note: </b>Additional segments of stone may be re-inserted into the brush holder if it is determined that additional resurfacing is necessary.

5
00:00:26,875 --> 00:00:32,333
Some pitting of the collector ring is normal and does not constitute a collector ring failure.

6
00:00:32,333 --> 00:00:35,542
Resurfacing will not remove all the pits.

7
00:00:35,542 --> 00:00:40,375
Continue with the process on other collector rings that require resurfacing.

8
00:00:40,375 --> 00:00:47,917
8. When the resurfacing is complete, clean up the collector ring and the surrounding area with compressed air.

9
00:00:47,917 --> 00:00:57,125
<b>Warning:</b> When using compressed air for cleaning purposes, an environment that is potentially hazardous to personnel in the immediate area is created.

10
00:00:57,125 --> 00:01:03,958
To prevent physical injury due to flying debris, observe all railroad and government safety regulations.
