Manual Technical Specifications & Document Data

System Logic and Hydrostatic Performance

The LR614 Series 4 is distinguished by its closed-loop hydrostatic propulsion, which allows for stepless speed control and counter-rotation. This manual contains the axial piston pump regulation data and hydraulic pressure tolerances necessary for driveline calibration. Since the loader arm is subjected to significant stress, the guide includes technical sections on flow-sharing control valves that facilitate simultaneous lift and tilt functions. Understanding the electronic pilot controls and the automatic engine-speed management features is essential for maintaining the LR614’s cycle times and fuel efficiency.
