The DX170LC-5 delivers outstanding performance with the high-pressure common rail fuel system on the engine and Electronic Power Optimizing System (EPOS). Choose between four work modes, auto-idle and machine diagnostics. Smart Power Control (SPC) improves machine efficiency while maintaining productivity through variable speed control and pump torque control. Each of the four power modes will function with SPC engaged or disengaged; however, SPC only is active in the digging work mode. Auto shutdown helps owners save fuel while the machine isn't working. The EPOS links to the engine's Electronic Control Unit, electronically synchronizing the engine and hydraulic system. The system enables power and work operating modes, electronic control of fuel consumption, auto-idle, hydraulic oil flow regulation and control, and machine diagnostics. It also improves control, allowing you to precisely place material and easily level ground.
