The MAN Lion's Intercity LE is a modern bus designed for efficient and comfortable passenger transport. This manual provides comprehensive information on its various features, including emergency operations, power supply management, and maintenance points.
Function Description
The Lion's Intercity LE is engineered to provide reliable public transportation. Its design emphasizes safety, ease of operation, and passenger comfort. Key functional areas include the emergency opening systems for doors, various methods for deactivating the engine and power supply, and clearly marked maintenance points for routine checks and repairs. The vehicle incorporates advanced electrical systems, a robust fuel delivery system, and a sophisticated refrigerant circuit for climate control. Chassis reinforcement ensures structural integrity and safety, while strategically placed jacking points facilitate maintenance and tire changes.
Usage Features
Emergency Opening of Doors:
The bus is equipped with both external and internal manual emergency opening mechanisms for its doors. To open the doors in an emergency, the lock washer must first be removed. Subsequently, the push button should be pressed, or the rotary switch turned to the right. This action depressurizes the doors, allowing them to be opened manually. For Door 1, an additional front button is available. If necessary, the mechanical main battery switch should be turned on before pressing this button. This front button can be found either directly visible or behind a front flap.
Deactivating the Drive and Power Supply:
Several methods are available to deactivate the engine and power supply, ensuring safety during emergencies or maintenance.
- Via Ignition Key or Toggle Switch: The primary method involves turning the ignition key to the "OFF position" and removing it, or actuating the dedicated toggle switch. This action immediately deactivates both the engine and the power supply.
- Via EMERGENCY-OFF Switch (Optional): An emergency-off switch provides a quick way to cut power. To use it, the red locking mechanism must be pushed forwards in the direction indicated by an arrow, and then the top of the EMERGENCY-OFF switch pressed. This deactivates the power supply and simultaneously activates the hazard warning system. After actuating this switch, the internal and entry lighting automatically activate as emergency lighting. It is important to note that rapid lowering of the vehicle is not expected as long as the air suspension system remains undamaged.
- Via Electrical Main Battery Switch (Optional): The power supply can also be deactivated using the electrical main battery switch. Pressing the bottom of this switch for two seconds will deactivate the ignition. To fully deactivate the power supply, the bottom of the main battery switch must be operated again for two seconds.
- Via Mechanical Main Battery Switch: For a complete power cut, the mechanical main battery switch can be used. This switch is located in the battery compartment. To access it, the battery compartment must be opened. Turning the main battery switch anticlockwise will deactivate the power supply.
- Via Toggle Switch in Engine Compartment: The engine can also be deactivated directly from the engine compartment. Pressing the toggle switch in the engine compartment downwards will shut off the engine.
Maintenance Features
The manual highlights several key areas for maintenance and service, indicated by specific symbols and diagrams.
- Emergency Opening of Doors: While primarily a usage feature, the emergency opening mechanisms require periodic checks to ensure they are functional and accessible. This includes verifying that the lock washers are present and that the push buttons and rotary switches operate smoothly.
- Low-Voltage Battery: The low-voltage battery is crucial for starting the vehicle and powering various electrical systems. Regular inspection of the battery's condition, charge level, and terminals is essential for reliable operation.
- Vehicle Electrical System: The comprehensive vehicle electrical system requires periodic checks for wiring integrity, fuse functionality, and component performance. Any issues with the electrical system can impact various vehicle functions, from lighting to engine management.
- Fuel Line: The fuel line system, including the fuel tank and associated piping, needs to be inspected for leaks, damage, or blockages. Ensuring a clean and intact fuel delivery system is vital for engine performance and safety.
- Vehicle Fuel Tank: The fuel tank itself should be checked for structural integrity and proper sealing. Regular monitoring of fuel levels and ensuring the tank cap is secure are part of routine maintenance.
- Refrigerant Pipe and Component: The refrigerant system, responsible for the vehicle's climate control, includes refrigerant pipes and various components. These should be inspected for leaks, damage, or corrosion. Proper functioning of the refrigerant system is critical for passenger comfort.
- Chassis Reinforcement: The chassis reinforcement points are designed to enhance the structural strength of the bus. While not typically a routine maintenance item, any damage to these areas should be addressed promptly to maintain the vehicle's structural integrity and safety.
- Jacking Points: Clearly marked jacking points are provided to safely lift the vehicle for tire changes or undercarriage inspections. It is important to use these designated points to prevent damage to the chassis and ensure stability during lifting operations.
The manual's detailed diagrams illustrate the locations of these components and features, aiding in both operation and maintenance. The clear labeling of each element ensures that operators and maintenance personnel can quickly identify and address specific parts of the vehicle. This comprehensive approach to documentation supports the safe, efficient, and long-term operation of the MAN Lion's Intercity LE.
