OPERATING PROCEDURES
In freezing weather, precautions must be taken to see that the cooling water does not freeze. See DRAINING COOLING WATER SYSTEM and follow railroad rules for this situation.
SAFETY CONTROL
Safety control consists of a foot-pedal-operated air valve, whistle, and a cut-out cock. Except when the locomotive is stopped and locomotive brakes are applied, the engineman must keep the safety control foot pedal depressed at all times. This prevents safety control brake application.
After a penalty brake application has occured, normal locomotive operation is restored in the following maner :
Move the throttle handle to IDLE.
Move the automatic brake valve handle to LAP.
Depress the safety control foot pedal.
Depress the penalty reset valve on the control console until the P-2A Brake Application Valve is heard to click. Then the valve can be released and allow the system to charge completely.
After the system has charged to normal pressure, move the automatic brake valve handle to RELEASE.
NOTE : Other forms of safety control may be provided. See railroad rules for specific procedures.
DRAINING COOLING WATER SYSTEM
For weather above freezing, the cooling water system may be drained by opening the main water drain valve and the air compressor drain valve, both on the right side of the locomotive near the base of the lub-oil cooler. See Figure 16.
