If Main Handle had been in notch 12 or above, wait 10 seconds before advancing Braking handle. Observe braking scale limits of traction motor load indicators. Do not operate in Red Band. If braking limit is exceeded the wheel slip light will come on and buzzer will sound. When this occurs notch back until light goes out.
Advance handle with judgement to bunch slack and to maintain desired braking effort.
Dynamic Braking cannot be obtained on any particular unit when any of its traction motors are cut out. Do not use dynamic braking on either unit if any traction motor is cut out. Do not use dynamic braking when a rectifier ground exists on any unit. Locomotive can now be motored. The automatic air will not apply on the locomotive during ordinary service brake application, but will apply in event of safety control or train speed control service application or an emergency application initiated by either the brake valve or train line.
