This system should not be used as a substitute for physically engaging the parking brake before leaving the operator station.
A Load Haul Dump machine equipped with the automatic parking brake system will automatically engage the parking brake under certain conditions. The system uses the Electronic Transmission Control to detect when all the following conditions are active for 3 seconds or more:
Parking brake disengaged.
Remote control switch is in the OFF position (if equipped).
Ground speed is less than 5 km/h (3.1 mph).
Engine rpm is between 550 rpm and 800 rpm.
Neutralizer pedal released (foot off pedal).
Service brake pedal released (foot off pedal).When all the above conditions are continuously active for 3 seconds or more, the parking brake will automatically engage.If the parking brake is automatically engaged, disengage the parking brake by cycling the parking brake switch from the OFF position to the ON position. Cycle back to the OFF position.Note: The optional ABA Transmission Switch Group must be installed with the Automatic Parking Brake system if not already installed
