Garden machinery: how to maintain garden tools?
There are different kinds of garden tools in garden machinery equipment, but how should we maintain them? How should we care for the accessories of gasoline engines, air filters and other machinery? Let us take a look at the maintenance methods of garden machinery 1. The four-stroke gasoline engine fuel is clean gasoline (above 90), and the lubricating oil is SAE30 four-stroke engine oil. The new machine is run in at idle speed for 2 hours, and the engine can be used normally after the engine oil is changed. During normal use, change the oil once every 30 hours. Check the oil level before and after each use. 2. When the four-stroke air-cooled gasoline engine works continuously, the crankcase temperature cannot exceed 90 degrees, and it can continue to work after stopping for 15 to 20 minutes when overheating. Fuel refueling must be performed in the cold state. The cooler should be used normally after running at low speed for 3 minutes. Do not use the maximum throttle for a long time without cutting grass. 3. Do not run the gasoline engine at an excessive speed. Except in emergency, it should be stopped at low speed. 4.

Air filter element should be checked frequently, washed with soapy water or replaced regularly. 7. After the gasoline engine has been running for 100 to 300 hours, use wood chips or bamboo chips to remove the carbon deposit once. Remove the cylinder head during cleaning to remove the carbon deposits attached to the cylinder, cylinder head, piston, valve, etc. Carbon deposits must not enter the cylinder bore and valve seat. 8. Keep the gasoline engine, especially the cylinder fins clean. 9. When refueling, checking, repairing, and maintaining, remove the spark plug cap, do not smoke, and stay away from open flames. 10. Do not operate indoors. In addition to the operator, unrelated persons leave the machine more than 15 meters while the machine is working. 11.
