| Hydraulics | ||
| The power train consists of one main drive. Diesel engine or electric motor can be supplied. One gearbox drives three identical main pumps which draw hydraulic oil from an unpressurized hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency. | ||
| The three-circuit Hydropilot system features electronic engine and pump management to optimise hydraulic power for smooth hydraulic action, fast response, simple system layout and a reduced number of components. Filtration is at the oil intake to pumps, valve blocks, heat exchangers and oil tank. | ||

| 2 heated rearview mirrors are externally mounted. External metal sun louvers and internal pull-down sun blinds. Left-hand sliding window. All windows are tinted parsol green. | ||
| Vehicle Monitoring System | ||
| The Electronic Text Monitoring (ETM) system, mounted in the operator’s console, continuously monitors the performance of the engine, gearbox, autolube and hydraulic systems. Fault messages are immediately available to the operator via a digital display and in the event of critical malfunctions the engine is also shut down. | ||
| The digital storage provides failure summary and analysis, which can be downloaded by laptop computer. This data will assist in predicting or reducing downtime. |
