Especially in rainy and Electric Single Wheel Barrow, the sticky sand particles make the chain sprocket wear early and shorten the life. The correct maintenance method is: After mixing clean 4T engine oil and hydraulic oil or transformer oil (available in stores) at a ratio of 1:1 or 1:2, use a clean brush to evenly drip the lubricant on the roller in the middle of the chain. A thin oil film is formed to protect the chain. After using it for a period of time, drip it again when the oil film is quick to dry.

The principle is "less oil, more frequency" and keep the chain tight enough so that the chain and sprockets will be clean and durable. 3. Motorcycle chain adjustment should be appropriate Motorcycle chains should be adjusted regularly as required, and they are required to maintain good straightness and tightness during the adjustment process. The so-called straightness is to ensure that the large and small chainrings and the chain are in the same straight line.

Only in this way can it be ensured that the chainrings and the chain will not wear too fast and the chain will not be dropped during driving. The tightness requirements are generally adjusted based on the tightness of the chain. The correct adjustment should be to pull the chain up and down by hand to make the chain move up and down within the range of 15mm to 20mm as the standard. Too loose or too tight will accelerate the wear or damage of the chain and chainring.

As for the method to maintain the life, the first is to clean up, which is to clean up the carbon deposits attached to the electrodes or insulators. Since carbon deposits are conductive bodies, when carbon deposits are attached to the spark plugs, the power leakage or splash sparks will be weakened, and the original cooling effect cannot be exerted due to the influence of carbon deposits; the spark plugs will not be damaged when cleaning the spark plugs. Just use a copper brush to clean it up completely. 2. Electrode shape modification and electrode gap adjustment As the use time increases, the shape of spark plug electrodes and their gaps will change. Especially the center electrode, after continuous spark splashing.

After that, the surface will become rough and the corners will peel off, so that the sparks are not easy to splash. Therefore, it is necessary to use a knife to reshape it to show the original smooth surface and complete corners. For this reason, the gap between the electrodes will be enlarged. After measuring with a thickness gauge, adjust to the originally specified gap. If you can do the above-mentioned regular maintenance, you can definitely keep the spark plug in good technical condition.
