The machine is equipped with a positive flow control system with variable flow. With this system, the working pump can
deliver flow according to demand. A variable flow from the pump allows precision work even with high engine speed.
The hydraulic system, also known as the “Automatic Sensing Work Mode,” is designed for high-productivity, high-digging
capacity, high-maneuvering precision and excellent fuel economy. The summation system, boom, arm and swing priority
along with boom and arm regeneration provides optimum performance.
The following important functions are included in the system:
Summation system: Combines the flow of both hydraulic pumps to ensure quick cycle times and high productivity.
Boom priority: Gives priority to the boom operation for faster raising when loading or performing deep excavations.
Swing priority: Gives priority to swing functions for faster simultaneous operations.
Regeneration system: Prevents cavitation and provides flow to other movements during simultaneous operations
for maximum productivity.
Power boost: All digging and lifting forces are increased.
Holding valves: Boom and arm holding valves prevent the digging equipment from creeping.
The following functions are included in the main control valve :
Optional equipment, X1
The optional control valve has the following functions:
Adjustable boom, X2
Optional equipment, X3
line rupture for boom and arm

Hydraulic system, description
The machine's hydraulic system is divided into two subsystems - the working hydraulic system and servo hydraulic system.
All power transmission is via hydra
