Use and maintenance of two-stroke power brush cutter

The first step: The two-stroke engine uses a mixture of oil and gasoline, and the mixture ratio is 1:50. The gasoline is more than 90, the oil is best to use two-stroke special oil, the symbol is 2T, and the use of four-stroke oil is strictly prohibited.

The second step: It is recommended that the new machine should be run in 30, 60 minutes before use, the ratio of oil and gasoline is 1:40, and the oil is distributed according to the normal ratio of 1:50 when working, and it is resolutely not allowed to exceed 1:50, otherwise the concentration is too thin, which will cause the machine to pull the cylinder. The oil should be distributed strictly according to the oil dispensing pot attached to the machine, and the oil should not be distributed at will. It is best to mix the oil with the current use, when the oil is shaken evenly, it is strictly prohibited to use the mixed oil with a long time.

Step 3: Before the machine works, check the oil, blades, nuts, bolts to ensure that the machine is in a safe operation state. Run at a low speed for a few minutes before working. When working, the fuel door can not be high and low, and the throttle should be used at a uniform speed.

Step 4: The length of the grass rope should be controlled, not more than 15 cm, if the grass rope is too long, it will affect the normal operation of the machine. The blade must be installed correctly and pay attention to balance. Before work and during rest, check whether the blade is loose. If it is loose, strengthen it in time.

Step 5: When storing, the body must be cleaned, the mixed fuel must be discharged, and the fuel in the carburetor must be burned; Remove the spark plug, clean up the carbon on the spark plug, and add l-2ml two-stroke oil to the cylinder, pull the starter 2-3 times, and install the spark plug. The lawnmower should be stored in a horizontal position, placed in a ventilated, dry place, away from electrical appliances and fire machinery to avoid fire.
