Match performance to the task using four work modes to tailor the excavator’s power for digging or lifting. Two of the modes change the auxiliary hydraulic flow to use different types of attachments or protect hydraulic system components.
This default setting delivers the power and response you need for general operation, from excavation to loading and lifting. The large excavator’s digging performance can be further enhanced with the four power modes.
While in digging work mode, SPC matches load to engine rpm, hydraulic pump torque and engine response, improving efficiency in any of the four power modes. Operators can activate it in digging work mode, and they can turn it off whenever necessary.
Breaker, or one-way auxiliary hydraulic flow, works great for attachments that only require hydraulic power from one direction, such as breakers or plate compactors.
Shear, or two-way auxiliary hydraulic flow, is best for excavator attachments that need bi-directional hydraulic flow, such as a hydraulic clamp, tilting bucket or shear.
