Hydraulic system
The hydraulic system, 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, priority systems, and
regeneration system provide optimum
performance.
1 Summation system: Combines the flow of both
hydraulic pumps to ensure quick cycle times and
high productivity.
2 Boom priority: Gives priority to the boom up
function for faster cycle times during loading and
deep excavations.
3 Arm priority: Gives priority to the arm operating
function for faster cycle times during digging and
dumping.
4 Swing priority: Gives priority to the swing
function during trenching application to improve
productivity.
5 Regeneration system: Prevents cavitation and
provides flow to other functions during
simultaneous operations for maximum
productivity.
6 Power boost: All digging and lifting forces are
increased.
7 Holding valves: Boom and dipper arm holding
valves are provided to minimize cylinder drifting
while holding loads.
