The hydraulic system has several improvements over
conventional hydraulic systems - including cross-sensing total
horsepower control - to maximize output efficiency.
The system features an electronically controlled output
optimization system, which allows the operator to choose
between two, distinctly different power modes: high-output/rapid
cycling maximum speed power mode, and a standard power
mode for most types of general operation.
Electronic management of hydraulic control valves assists in
optimizing the application speed and overall operator control of
hydraulic actuators and functions.
