SECTION 8
PUMPS
The hydraulic system is controlled by 3 pumps, 2 main ones and an independent one for slewing. The engine
and the pumps are monitored by the "Power Limit Control" system.
Up to 7 power levels can be selected for digging and lifting, included the levelling mode for fine works. The
power level can be increased automatically with "Drive" mode.
Main pumps ........................................................................... No. 3 at variable displacement, at axial pistons.
