The purpose to maintain the excavator in regular time is to reduce the faults of machine, prolong machine's working life; shorten the downtime of machine, improve the working efficiency and reduce the working cost. As long as managing fuel oil, lubricating oil, water and air of excavator parts can reduce 70% faults. In fact, 70% faults are caused by poor management.
Details to Maintain Excavator
Firstly, We should select different diesel oil according to various environmental temperatures. And the diesel oil cannot be mixed with impurities, dust and water, or the fuel pump may be worn in the early time. Paraffins and sulphur which take up mostly in bad fuel oil will do harm to excavator engine parts. The fuel tank should be filled with fuel oil every day after work to prevent water-drop. Before everyday operation, we should open the bottom of fuel tank to turn on the water. Secondly, different oil in various levels cannot be mixed together. We have to guarantee the clean of oil, and prevent impurities (water, dust and particles). The oil with high viscosity should be used in low temperature. Thirdly, we should also pay attention to filter element, and filter oil and impurities to prevent them entering into the interior of system to cause some faults. In addition, filter element should be changed in regular time, and take some efficient measures to improve it if some metal particles adhere to the components. Fourthly, lubricating oil can reduce the wearing on the moving surface to prevent the noise. When we add oil, the old oil should be forced out totally.
Regular Maintenance
When the machine has to be stored for a long time, the working device should be placed on the ground to prevent the rust of hydraulic cylinder piston. The whole machine should be cleaned and dried in the room. If it is limited by condition, the machine has to be placed in outdoor, and we should place it on cement court with excellent drainage. The machine should be operated every month to lubricate every moving component, and charge the storage battery at the same time. We should also make some inspections before starting engine. Examine the height of cooling liquid, oil level of engine and add some oil. In addition, examine whether the element air filter is blocked, whether rthe horn is in normal, and we should also examine the lubricating of bucket and sediments in oil-water separator. Do not clean the machine when the engine is working, because the high-speed revolution will cause some dangers.
