Excavators how to care? 2, launched engine oil, hydraulic oil, gear oil management. Remember not to put different brands and grades of oil mix; to ensure that oil clean to avoid debris (water, dust, particles, etc.) mixed;? Depending on the ambient temperature and the use of the use of different labels used mini excavators sale of oil, the ambient temperature high, the viscosity of the oil used mini excavators Komatsu, the ambient temperature is low, the selection of a smaller absolute viscosity oil; the larger the absolute viscosity gear oil, in order to conform to the large transmission load; viscosity hydraulic oil is relatively small? aim to increase the liquid active resistance. With the expansion of China's construction machinery market, the purpose of buying groups become more rational. According to experts, the import of used mini excavators, future purchases of small construction machinery main groups: First leasing company.
