Multiple operation modes available via monitor: Eco, Standard, Heavy Mode, suitable for municipal reconstruction, foundation excavation, pipeline laying, bulk earthmoving and medium light rock breaking projects. All hydraulic cylinders are equipped with built-in double anti-shock buffer valves to suppress vibration under medium and light load operation. Factory pre-installed full auxiliary hydraulic piping for hydraulic breaker, compatible with 85–110mm hydraulic hammer without secondary modification. Exclusive CAT intelligent load sensing hydraulic system automatically adjusts pump flow according to joystick signal, reduces idle fuel consumption by 12% during standby, delivers smooth, precise and fuel-saving operation response. Auto idle function reduces engine speed automatically after 3 seconds without operation to save fuel consumption.
