What are the daily maintenance methods for garden tools?

The daily maintenance methods of gardening tools include:
1. When the four-stroke air-cooled gasoline engine is working continuously, the crankcase temperature cannot exceed 90 degrees, and it can continue to work after 15 to 20 minutes of shutdown when it is overheated. Fuel filling must be carried out in a cold state. The cold engine should be used normally after running at low speed for 3 minutes. Do not use the maximum throttle for a long time when not cutting the grass.
2. For other lubrication parts of the machine, add lubricating oil or grease regularly according to the instructions.
3. Check the tightness of the bolts in the working part and other parts before and after each use of the machine.
4. Do not run the gasoline engine at excessive speed. Except in emergency situations, stop at low speed.
5. The fuel of the four-stroke gasoline engine is clean gasoline (above No. 90), and the lubricating oil is SAE30 four-stroke engine oil. The new machine has been idle for 2 hours and can be used normally after the engine is warmed up and the oil is changed. In normal use, the oil should be changed every 30 hours accumulated work. Check the oil level before and after each use.
6. Do not operate indoors. When the machine is working, apart from the operator, unrelated persons are more than 15 meters away from the machine.
7. Keep the gasoline engine, especially the cylinder fins clean.
8. Non-professionals are not allowed to adjust the carburetor. When adjustment is necessary, generally tighten the oil needle clockwise slightly, and then turn it counterclockwise for 1.5 to 1.75 weeks.
