Maintenance principle: First, implement the method of combining scheduled maintenance and temporary teleskop radlader 1000kg maintenance with fixed factory, fixed personnel, fixed vehicle. Use the teleskoplader correct transmission system oil, and the lubricating oil used in the gearbox must comply with specifications. It should be noted that diesel engine oil should not be added to the gearbox, as diesel engine oil reduces friction between moving parts such as pistons, while transmission system oil requires a certain amount of friction between the friction plates during engagement, which is crucial for the normal operation of the transmission system. Only mini telescopic loader by using lubricating oil correctly can the working life of clutch friction plates be effectively extended. At the same time, using the correct oil can significantly improve the wear resistance of gears, eliminate clutch slippage, control brake shaking and abnormal noise, increase braking force, and telescopic mini loader provide greater traction. At present, the telescopic boom loader most commonly used hydraulic transmission oils for gearboxes are 6 # and 8 # hydraulic transmission oils.Second, implement the method of combining self repair by drivers, repair by the company's maintenance team and external repair of major difficult faults. Third, the driver should check, maintain and maintain the vehicle frequently to keep the vehicle with good technical performance at any time. all wheel loader with CE approvel . www.haiqinmachinery.com
