1. During the use of lawn mowing machinery, regular inspection should be carried out and correct operation specifications should be strictly complied with, so as to avoid the damage of machinery to human body and illegal operation to machinery, as well as some unnecessary accidents and failures. Before each use, it is necessary to check whether the amount of gasoline and lubricating oil is sufficient. If insufficient, it should be filled in time to avoid the scrapping of the engine due to the insufficient amount of lubricating oil.
2. In the process of use, we should pay attention to the reliability of the working of the moving parts and transmission parts of the machinery, and check whether the clearance size is in the normal working range. If there is a problem, it should be adjusted in time; Check fastener firmness, if loose should be strengthened in time; Listen to the abnormal sound of machinery, confirm the disease signs and timely maintenance. Some problems can be solved or controlled by adjustment, lubrication and other methods. They should be solved in time to avoid major operations such as mechanical overhaul or disintegration, which will affect maintenance management and cause unnecessary increase in maintenance costs.
3. Lawn mowing machinery must be maintained regularly in the process of use, to achieve "three points by repair and seven points by maintenance"; Must be in strict accordance with the engine requirements of fuel and lubricating oil label, quality and mixing ratio (two-stroke gasoline engine) for refueling. For example, the lubricating oil of B&S engine should use SAE40 oil. The oil of the engine should be changed after 5 hours for the first time and every 50 hours after running in. Gasoline should be no. 93 or above or unleaded.
