To make small four-wheel tractors strong, vigorous and long life, must be scientifically managed and used. Do not speak science, do not follow the rules, it is a poor tractor.
1. Seriously run in. Newly-manufactured tractors cannot be used immediately after they are bought back. The machine must be ground for a time, so that the various parts can be better fitted and engaged. If you use it immediately, it will cause some damage. The running-in of small four-wheel tractors is usually divided into three stages: engine idling, tractor empty line and carrying load. The tractor moves from static to dynamic, the speed is from low to high, and the load is from small to large. Each stage has certain requirements. In the running-in, it is necessary to observe the working conditions of the engine, but also pay attention to the working conditions of the clutch, gearbox, steering gear, and brakes. If problems are found, they should be promptly resolved.
2. Oil and water are adequate and clean. In order to ensure the normal operation of the engine, you must add enough cold water to the tank, add enough diesel to the tank, and add enough lubricant to each lubrication area. Water is added to reduce the temperature of the engine. Water should be soft water containing no or less calcium and magnesium salts, such as rainwater, well water after boiling precipitation, and river water. If hard water or dirty water is added, the water tank and radiator may easily clog or generate scale, causing the engine to overheat.
3. Carry out items on time. A small four-wheel tractor will be required to perform class maintenance when working 10 hours a day or using 20 kg of diesel fuel. Each time one hundred hours, five hundred hours, and one thousand hours of work, one-level, two-level, and three-level technical maintenance are performed. Each technical maintenance has fixed items and content. If maintenance is carried out during the shift, remove dirt, dust and grease from all parts of the tractor; check engine oil level after stopping the engine for 10 minutes; check tank water volume and tank oil level; check for leaks or oil leaks at joints. , Leakage phenomenon; check the air pressure on the wheel; check the tightening of the external nuts and bolts; check whether the oil pressure indicator is normal.
4. Carefully use and use. The first step to use is to start. The correct method is used for starting. If the method is not correct, not only can it not start but it can also fly out of wounds. After starting, warm up after low speed operation. Walk straight and use the proper speed. It was found that the sound of the engine was heavy and black smoke could be reduced by one grade. In case of obstacles, you must not use the method of violently taking off the clutch, nor should you always put your feet on the pedals of the clutch or brake, or even change the speed with the clutch. The ramp should be operated at a low speed. It is not allowed to shift gears midway, and it is forbidden to coast and brake suddenly, not to make a sharp turn at high speed. Temporary parking, to turn off. Some people often throw a few throttles when they are off. This habit is not good. It not only accelerates the wear of parts, but also easily deposits carbon.
Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
