Turn off the oil circuit switch under the oil tank. There is an oil pipe between the oil circuit switch and the carburetor. Pull out the tubing connected to the carburetor and put it into the container.

Pay attention to your health

1, the maintenance of the fuel tank, mainly combined with the first-class maintenance of the automobile, releases the water and dirt in the fuel tank and checks whether there is oil leakage at the oil pipe joint and switch. For the tank cover with air valve and steam valve, check whether the vent hole is clear.

2. The filter screen of the fuel filler should be kept intact-to avoid impurities entering the fuel tank and blocking the oil circuit when refueling. The gasket of the fuel filler cap should also be intact to avoid the oil in the fuel tank from overflowing when driving.

3. After the car is used for a period of time, the fuel tank should be thoroughly cleaned and overhauled. When cleaning the fuel tank, wash the inside with hot water first, and then blow dry with compressed air to remove the gasoline vapor in the fuel tank. Then, put the gasoline tank into an aqueous solution containing 10% sodium hydroxide, and wash the inside and outside of the tank with flowing water after soaking.

4, also can use 5% caustic soda boiling water solution after cleaning, then rinse with hot water. If there is rust on the outside of the fuel tank, clean it with a wire brush and paint it. After cleaning the fuel tank, check the tightness.

5. During inspection, all the orifices of the oil tank should be blocked with rubber plugs, then immersed in water, and compressed air should be input from the connecting hole of the oil pipe. If there is air bubble in a certain part, it is air leakage. At this point, mark the leakage, and then weld after paint removal.

Matters needing attention

1, don't go to the car wash shop or ask others to help you wash your car unless you have to. Car wash shops seem to have complete tools and standardized operation, but there are also cases of pursuing efficiency and poor results. If it is not good, it will also cause cremation plugs and various lines to break down.

2. Be sure to let the hot car cool before washing the car. Suddenly washing the engine, exhaust pipe and other parts with cold water, the principle of thermal expansion and cold contraction is very clear to everyone, which will destroy the oil seals of various parts and lead to oil leakage of the engine. Many motorcycle engines leak oil slightly. It will also cause the chromium plating layer at the joint between the exhaust pipe and the engine to fall off and oxidize and rust.

3. Headlights, left and right handrails, switches, exhaust holes (preferably plugged with something), speakers, cremation plugs, air filters, batteries and other components are best not to be washed directly with water. These parts have circuits, which will lead to short circuit or leakage, and there will be failures such as no light, no horn, no fire and driving fatigue. You'd better scrub them with a rag.

4. When washing the car, you must clean the lower part of the engine and the radiator. It is recommended to dip it in a toothbrush for cleaning. The advantage of this is that it is beautiful and easy to find problems such as oil leakage.

5. After washing the car, dry the whole car with a dry rag, especially the switch, instrument, left and right handrails, cremation plug, fuel tank cover and other parts. Pay special attention to take off the cremation plug cap and shake it a few times, otherwise it will affect the ignition.

6. After drying, start the vehicle, idle sideways for 5- 10 minutes, drain the water in the exhaust pipe, then drive on the road at a medium speed for a few minutes or dry in the shade, and don't explode in the sun.

7. Every time it rains, after riding home and putting the car in storage, pay attention to dry the car, especially the exhaust pipe. Now the pollution is serious and the rain is acidic. Most of the exhaust pipes have long been rotten. Although it is troublesome, it is definitely the way to love a car.

8. After cleaning the car, you can spray wax on the shell, rub it evenly with a fine emery cloth, and re-lubricate the chain.
