The 2 tonne excavator plays an important role in city construction and infrastructure development, especially in the small-sized engineer construction. Being compact and flexible, the mini digger can be used in narrow space where the large digger can not reach to make the maximum productivity, thus becoming the representative construction machinery in city construction. Built to be the best digging tool, Sany mini digger features with high efficiency, low fuel consumption, high safety, low pollution and ease of operation, making great contribution in saving labor and resources.
Regular maintenance should be made to keep the 2 tonne excavator in a good condition, especially in winter, during which the freezing temperature will cause damages to the hydraulic parts. Before starting working, the excavator should be set in idle running with low speed for several minutes, then speed up the engine to the maximum and make the bucket and rod running for 5 minutes. Attentions should be paid to the ambient to avoid injuring people or other objects around when preheating.
If the 2 tonne excavator is idle in winter, special care should be taken to the machine to make it ready for immediate use. Clean the surface of the machine and check the parts to avoid loose bolts. Keep the fuel oil and antifreeze in good quality and normal work. If the machine needs to be idle for a long time, the engine coolant should be discharged completely and the accumulator should be stored in warm place.
