OM3013 02/99 Operation - Section 3 Operating Instructions Page 3-19 Emergency Brake Lever (5, Figure 3-2) When the lever is set to the PARKING position, if the transmission shift lever is at any position other than "N", the central warning lamp will flash and the alarm buzzer will sound. If the air pressure drops below 215.7 kPa (2.2 kg/ cm 2 , 31.2 psi), the parking brake is automatically applied. For details of the method of releasing the brake when it is applied because of failure in the air system, see BRAKE RELEASE. The lever (5) actuates the emergency brake. EMERGENCY BRAKE RELEASED: (TRAVEL / UNLOCKED position). EMERGENCY BRAKE ACTUATED: (APPLIED / LOCKED position).
ENGINE ELECTRONIC CONTROL SYS- TEM If the pressure in the air tank drops below 411.9 kPa (4.2 kg/cm 2 , 59.7 psi), the emergency brake is automatically applied. The following items (7, 8, 9, 11, & 12, Figure 3 -2) relate to the engine electronic fuel control system. If an abnormal engine condition develops, the control system will record a "fault" code associated with that condition. By use of a series of indicator lamps and switches, the system will display the numerical "fault" code. If the emergency brake is applied because of a failure in the air system, the central warning lamp will flash and the alarm buzzer will sound.
For details of the method of releasing the brake if this happens, see BRAKE RELEASE, Page 3-13. When the keyswitch is turned "On", the lamps (7,8, 9) should illuminate for about 2 seconds and then turn "Off", if no "faults" are detected in the system. This is a system lamp test. Parking Brake Valve Lever (6, Figure 3-2) This lever (6) is used to apply the parking brake. If a light remains ON, or if a light FLASHES, then active "faults" have been detected by the system and the engine should not be started until the condition has been corrected. Refer to DETERMINING "FAULT" CODES. When the lever is set to the PARKING position, the parking brake pilot lamp lights up.
During engine operation, if a "fault" is detected in the system, a light associated with that condition will turn "ON" and stay on for "Warning faults", or it will turn "ON" and "FLASH" for more severe faults that canaf- fect engine operation and require immediate atten- tion. Always apply the parking brake when parking or leaving the machine. Brake actuated. (Locked) ake released. (Unlocked)
