In order to ensure that our quality can reassure and satisfy customers

We will conduct a detailed inspection of each excavator to ensure that each one is in good working condition. Before the machinery is dispatched, for each piece of equipment, we will replace the engine oil, hydraulic oil, gear oil, new air filter, oil filter, diesel filter, as well as the oil inlet/return/pilot/pipeline filter elements. Other damaged parts will also be replaced with new ones
