• The low-pressure fuel system with an electrically controlled governor allows the engine to be more robust with quality fuel.
• Boom and stick regeneration valves help reduce fuel consumption.
• Highly efficient hydraulic pumps deliver optimal power to suit general construction applications.
• The machine’s China Nonroad Stage III and U.S. EPA Tier 3/EU Stage IIIA equivalent engine can run on biodiesel up to B20 that meets ASTM 6751 standards.

• Multiple seat and joystick adjustment options enhance comfort.
• Excellent work site visibility from the cab enhances productivity and safety.
• Low-effort joystick controls reduce operator fatigue.
• The automatic climate control system with 10 vents maximizes comfort.

Serviceability

• Most service locations can be accessed at ground level.
• The fuel filtration system has two filters, both located in the radiator compartment, rather than three filters as in the 312D, lowering O&O costs and simplifying service.
• Remote-mounted filters reduce the time to service the machine.
• Pressure taps and S·O·SSM ports help maximize uptime.

Technology
