or realistic people report, but do not know what tools to repair machines, which is to provide a detailed point, thank you!
Full set of six angle wrenches. A multimeter。 If the circuit repair, but also dedicated computers. Cartridge wrench. Do you want to import machines from a set of 12 ring spanner is commonly used open again. Do you want to change the hydraulic oil seal special tool specific what to see what brand of excavator.
Regular maintenance of excavator can reduce the breakdown of the machine, prolong the service life of the machine, shorten the down time of the machine, improve work efficiency and reduce operation cost. As long as the fuel, lubricating oil, water and air are managed properly, 70% of the failures can be reduced. Fuel management according to the different environmental temperature with different grades of diesel oil; diesel oil can not be mixed with impurities, dust and water, otherwise it will make the fuel pump premature wear; content of paraffin and sulfur in the fuel is high, will cause damage to the engine; the daily operation after the fuel tank to fill the fuel tank wall, to prevent the generation of water drop the water drain valve; open the fuel before the daily work. Other oil management of other oil includes engine oil, hydraulic oil, gear oil and so on; different grades and different grades of oil do not mix additives;
different varieties of excavator oil in the production process to add the chemical or physical interaction is different; to ensure the oil clean, to prevent debris (water, dust particles, etc.) into according to the label; the ambient temperature and the use of selected oil. Environment temperature is high, should choose the viscosity of big oil, low temperature environment, should choose a small viscosity oil. Gear oil viscosity is relatively large, to adapt to larger transmission load, hydraulic oil viscosity is relatively small, in order to reduce liquid flow resistance. Grease management uses grease (butter) to reduce wear and tear on the moving surface and prevent noise. Grease storage, can not be mixed with dust, sand, water and other impurities; recommended lithium based grease G2-L1, good abrasion resistance, suitable for heavy duty; filling, as far as possible all the old oil extrusion and clean, prevent sand adhesion. The maintenance of filter filter filter impurities oil or the role of gas, prevent its invasion within the system caused by the fault; according to the different kinds of filter elements (operation and maintenance manual) requires regular replacement; replacement of filters, should check whether the metal is attached to the old filter, if found to have metal particles, should be timely diagnosis and take improvement measures; use in accordance with the provisions of the pure filter machine.
