1, the engine oil maintenance projects plane, fuel tank, fuel tank vent hole, oil-water separators, air filters, liquid cooling system, engine operation is normal or not pass. 2, electrical equipment maintenance item check each meter, indicator lights, electrical system cable, generator performance, battery 3, the maintenance of the transmission system leaks 4, mobile machinery maintenance Four Wheels loose 5, hydraulic maintenance of oil hydraulic oil system, hydraulic system leaks 6, the whole project to clean the whole car maintenance, fastening bolts, check each component performance, lubricate the hydraulic excavator metaphor if a person, then the hydraulic system the equivalent of the human circulatory system. Hydraulic circulatory system is a hydraulic excavator is extremely important part of the small excavator price list, which includes the production of precision: the main hydraulic pumps, hydraulic tank, multiple valves, cylinders, motors and lots of piping. Because of its production of precision, the hydraulic system is actually very "fragile", we need well-maintained; if not maintenance or improper maintenance can lead to all kinds of failure, affect your huge loss. Maintenance of the hydraulic excavator: Cleaning articles 1 to keep clean hydraulic oil. Hydraulic oil must be placed in the position of second-hand small excavator clean price, oil changes is to use the grid with a fine filter funnel clean oil from the container into the tank if the hydraulic oil contains impurities will stuck valve, abrasions pump, blocking ports, causing malfunction. 2 To keep clean the system. Periodic replacement of the hydraulic oil and hydraulic oil filter. Because there are a lot of hydraulic oil additive, had the role of these additives is to prevent deterioration of hydraulic oil, but will expire after 5000 hours, this time should be replaced with new hydraulic oil up. In addition to oil changes should also be regularly excluded outside of the tank water and sediment small excavator, if the fuel tank of a precipitate smallest excavator price, without cleaning, replace the hydraulic oil is not useful. 3 To keep the work area clean. In the tank when refueling, make sure the area is clean around the filter cover. Use only clean funnel or container. Never dirt with human systems. Maintenance of the hydraulic system, only the clean plastic plugs for end wiper pipeline. Maintenance of hydraulic components, workstations must be absolutely clean. Check status of the use of tools, they must be cleaned. Small excavators and heavy price list _ _ Ka Liaoning small excavator by 泰安嘉 and Heavy Machinery Co., Ltd.泰安嘉 and Heavy Machinery Co., Ltd.
