1. Choose lubricating oil correctly according to the season. Summer and winter lubricants should not be mixed. Summer lubricating oil is easy to be heated to dilute, poor oxidation resistance, easy to deteriorate, and even cause failure such as burning tile holding shaft. Therefore, the crankcase and gear box should be replaced with summer lubricating oil, often check the quantity of lubricating oil, oil quality, and timely replacement.
2. After the water tank is boiled, do not open the tank cover by hand immediately. In case of accident, the cooling water can not be added immediately, easy to cause the cylinder head or cylinder block "crack". Do not immediately turn off the engine, should idle for a period of time, and then add cooling water after the cooling water of the engine cools down naturally.
3. Agricultural machinery that is not used for a long time should be placed in the garage as far as possible. If placed in the open air, the tracks or tires should be padded with thick wood to prevent corrosion and aging of rubber parts. Cut off the power and turn off the main power switch. Remove the battery negative wire or unload the battery for ventilation and storage.
4. Timely clean the soil and weeds on the agricultural machinery. Unload the exhaust pipe and clean the sewage sediment inside. Clean the engine surface oil in time. If the oil pollution outside the engine is too thick, it will affect the heat dissipation and bury hidden dangers for the failure of various parts. By high-pressure injection method, the engine parts will be cleaned with cleaning agent that does not corrodes the body parts.
5, cool body explosion-proof tire. Summer temperature is high, tire rubber is easy to aging, serious will appear tire burst phenomenon. Therefore, the tractor should check the tire pressure at any time in the driving, and find that the tire is overheated and the pressure is too high. It should be parked in the shade to cool down, and can not be splashed with cold water, otherwise it will lead to a tire burst on the way.
6, in order to prevent the engine from overheating, maintenance, should pay attention to the fan belt can not touch oil, to prevent skidding, the belt should be kept as tight as possible. During the long journey, we should pay attention to timely rest, try to choose a cool place, and open the hood for ventilation and heat dissipation. When the tire pressure increases due to heat, it should be stopped immediately to cool down, or there is a risk of tire burst, special attention should not be used to deflate and pour cold water to reduce the tire pressure and temperature.
Attention: maintenance of agricultural machinery to do the "three", that is, hand, eye and ear attendance. General agricultural machinery and tools in the failure before there will be abnormal phenomenon, such as can do "three attendance", the various failures of agricultural machinery and tools will be found and eliminated in time, so as to reduce unnecessary losses.
