Carry out regular maintenance on Excavator that reduce machine failures, extend the life of the machine; to reduce machine downtime; improve efficiency, reduce operating costs. Selection of different grades of diesel fuel management: different ambient temperature; diesel can not be mixed with the magazine, dust and water, otherwise, will enable the fuel pump to premature wear; high paraffin and sulfur content in the low-quality fuel, the engine will produce damage ; daily operations after the fuel tank to fill the fuel to prevent the tank wall to produce water droplets; open the fuel discharge valve of the bottom of the water before the daily operations; Although the road in the air, to be ranked in the engine fuel exhaustion or replace the filter.
Two other oil management
Different varieties excavator oil added in the production of chemical action or physical effects of different additives; to ensure that the oil clean to prevent debris mixed; selected according to the ambient temperature and use the oil label. High ambient temperature, the viscosity of the oil should be used, the ambient temperature is low viscosity of the oil should be used; gear oil viscosity is relatively large, to accommodate a larger load of the transmission, hydraulic oil viscosity is relatively small, to reduce the liquid flow resistance.
3 of lubricating
 The lubricants can reduce wear of the moving surface, and prevent noise. Grease storage custody can not be mixed with dust, sand, water and other impurities.
(4) filter management
Play the role of filter impurities in oil or gas line filter, to prevent its intrusion within the system may cause a malfunction; filter should be changed regularly in accordance with the requirements; replace the filter should be checked whether there is metal attached to the old filter, such as metal particles Woodland timely diagnosis and remedial action; comply with the provisions of the machine pure filter.
Five other tests of management:
(1) Check th e engine oil, fuel and coolant leaks.
(2) the availability of loose bolts and nuts.
(3) in an electrical circuit, wire breakage, short circuit and the battery connector is loose.
(4) whether there is oil.
