There are many kinds of garden tools, but some of them are familiar, some are unfamiliar to us. They play a big role in greening, especially the rapid development of modern urbanization, and landscaping has become a landmark impression of the city. The tools for garden construction are of course inseparable from these garden tools, and we have some understanding of their use and maintenance.

　　Garden tools often endure very heavy work in use, so if you can extend their lifespan to make it easier to use and maximize your functions, you must know the relevant maintenance knowledge. For example, if you use less garden tools in winter, trim the lawn and lawn machine, hedge trimmer or chain saw, etc., you must put off the oil in the fuel tank, then add the appropriate new oil according to the instructions, then remove the spark plug and add the oil. Then put the spark plug on, and then wipe the dust and oil traces on the cutter head, the body and other parts, and put them in the proper position. In the spring and summer, the use of these tools will increase accordingly. First, check whether the screws or parts of these machines are firmly installed, whether they are loose, and whether the oil is enough or not. Do not overspeed when using, the oil used should be reliable, clean and fresh. Non-professionals are not allowed to adjust the machine without authorization. Remove the spark plug cap during refueling, repair and maintenance. Do not smoke or keep away from fire. If the machine emits blue smoke during use, it is probably caused by the burning of the oil. It is likely that the oil is too large and needs to be removed before use, or it may be caused by air filter blockage and blade not sharp. In addition, when the grass is too dense, it will also cause smoke. At this time, the size of the trimming should be increased, and the engine load can be reduced to solve such problems.

　　When the lawn mower is trimming the lawn, sometimes it will be weak. First, clean it first. If it can't be cleaned, replace the blade or sharpen the blade to make it sharp. If the center screw of the blade is not tightened, first check for damage, then tighten the screw before use. Sometimes the lawn machine does not have the best results. The first thing to do is to clean it. If the dirt is not airtight, it will cause the grass to be intensive. In addition, the blade will wear excessively, the blade will not collect grass, and the engine will be Excessive wear and high power loss. The lawn mower will also experience jitter when it is used. It may be caused by hard objects such as stones and roots when it is used, causing the blade to curl or the crankshaft to bend when the machine is severe. When using the hedge trimmer, use qualified gasoline and engine oil. After using one box of engine oil, rest for about ten minutes to ensure heat dissipation. Check the air filter and spark plug regularly when using the brush cutter to ensure the normal use of the machine.
