00:00:00,000 --> 00:00:04,667 
Typical steps to remove the steerable truck from under the locomotive are as follows:

2
00:00:04,667 --> 00:00:15,333
<br><b>Warning:</b> Disconnect the Multiple Unit (MU) jumper cables connecting the locomotive being serviced to any other equipment prior to performing any maintenance tasks.

3
00:00:15,333 --> 00:00:19,542
Hazardous voltages may be present between interconnected units. 

4
00:00:19,542 --> 00:00:25,917
Failure to disconnect the MU jumper cables from the locomotive being serviced may result in injury or death.

5
00:00:25,917 --> 00:00:32,458
<b>Note: </b>Ensure that the locomotive is on a straight track before any adjustment or replacements are made.

6
00:00:32,458 --> 00:00:39,500
1. Chock at least two sets of truck wheels on both trucks to prevent the locomotive from rolling in either direction.

7
00:00:39,500 --> 00:00:46,208
2. Release the hand brake, if set, and allow time for the truck wheels to seat against the wheel chocks.

8
00:00:46,208 --> 00:00:53,167
<b>Warning: </b>To eliminate air braking force, ensure that the cut-out cock of the truck that is being worked is closed.

9
00:00:53,167 --> 00:00:59,917
<b>Warning: </b>Ensure that the truck wheels are chocked and release the hand brake before cutting out the brake cylinder air.

10
00:00:59,917 --> 00:01:03,375
Ensure that air is cut out to only one truck at a time.

11
00:01:03,375 --> 00:01:12,500
Unexpected motion can occur if the wheels are not chocked, if the hand brake is set when brake air is released, or if the air is cut off to both trucks at one time.

12
00:01:12,500 --> 00:01:16,875
Unexpected rolling of the locomotive can cause serious injury or death.

13
00:01:16,875 --> 00:01:23,208
<b>Warning: </b>Follow all Railroad Operating Procedures governing compressed air and air lines.

14
00:01:23,208 --> 00:01:31,042
3. With the locomotive secure, locate and close the truck air cut-out cock on the underside of the locomotive frame.

15
00:01:31,042 --> 00:01:35,792
<b>Note: </b>Close only the truck cut-out cock for the truck being removed.

16
00:01:35,792 --> 00:01:42,875
Disconnect the hose to the brake cylinders of that truck only after all air has been exhausted from the truck air lines.
