4. High quality and best service.
The imported engine with original packing has strong power, and can meet the requirements of high-efficient work.
- Precise matching design with advanced energy conservation control can reduce the oil consumption of the machine.
- Low emission meets the Europe II standard.
- The adoption of new cooling fan and large-scale silencer lowers the noise of the machine.
- The adoption of the advanced turbocharging technique increases the highland adaptability of the machine.
- Automatic preheating system improves the working capacity in the low temperature.
- Unique fan cover with the shape of hopper opening greatly improves the air supply of the engine and the radiating capacity of the system, guaranteeing the successive high-efficient work of the machine.
- Restart prevention system effectively avoids the misoperation, and improve the use security of the machine.
