The machine's Intelligent Power Control System increases digging force by up to 10 percent for 10-second inter- vals. The no-time-limit, heavy-lift system enables the operator to increase pres- sure to build force and reduce hydraulic flow to the attachment, while reducing speed. An automatic boom-descent regeneration system allows the boom to descend faster. A multi-working-mode selection system gives the operator the ability to match performance with the job.
