1. Maintenance of engine oil
Before using the lawn mower, check the oil level to see if it is between the upper and lower marks of the oil dipstick. The oil should be changed after the new machine is used for 5 hours, and the oil should be changed again after 10 hours of use, and then the oil should be changed regularly according to the requirements of the manual. The oil change should be carried out when the engine is in a warm state. Do not add too much oil, otherwise there will be black smoke, insufficient power (too much carbon deposit in the cylinder, small spark plug gap), and engine overheating. The engine oil should not be too little, otherwise, the engine gear will be noisy, the piston ring will be worn and damaged at an accelerated rate, and even rags will appear, which will cause serious damage to the engine.
2. Maintenance of air filter
Before and after each use, check whether the air filter is dirty and wash it frequently. If it is too dirty, the engine will be difficult to start, black smoke, and insufficient power. If the filter element is paper, you can remove the filter element and dust off the dust attached to it; if the filter element is spongy, it can be cleaned with gasoline, and some lubricating oil should be properly dropped on the filter element to keep the filter element moist. Conducive to the adsorption of dust.
3. Maintenance of radiator
The main function of the radiator is noise reduction and heat dissipation. When the lawn mower is working, the flying grass clippings will adhere to the radiator, which will affect its heat dissipation function. In severe cases, it will cause the cylinder to be pulled and damage the engine. Therefore, carefully clean the radiator after each use of the lawn mower. On the sundries.
4. Maintenance of the mowing head
The cutting head is in a high-speed and high-temperature state when it is working. Therefore, after the cutting head has been working for about 25 hours, 20 grams of high-temperature and high-pressure butter should be added.
