In summer, the weather is hot and the tractor has a poor working environment. Please pay attention to the following points when using it:
(1) To prevent the water temperature of the water tank from being too high.
In summer, the cooling water of the tractor evaporates and consumes quickly. Before leaving the vehicle, sufficient cooling water must be added and the water level should be checked regularly during work. One-cylinder diesel engine without water temperature meter should always pay attention to the height of the red mark of the water tank float. If the float can not be used normally, it should be repaired in time. If there is a pot-opening phenomenon in the work, do not add cooling water directly. Stop the work and make the generator decelerate. After the water temperature is reduced (about 60), add the cooling water slowly to prevent the tank from cracking due to cold.
(B), to ensure the best time for oil.
In summer, the tractor's fuel supply time should be adjusted. If the oil supply is too early, the engine will produce a knocking sound, and sometimes there will be a reversal phenomenon; the oil supply time must not be too late, or the engine will not work.
(c) Maintain proper tire pressure.
It is advisable to inflate the tires of the tractor to 2% - 3% below the standard pressure to avoid puncture. After parking, it is best to park the tractor in the shade or in a ventilated and shaded place. When parking under the hot sun, cover the tires with straw or the like.
(D), the use of large viscosity lubricants.
Large viscosity of lubricating oil can improve the performance of lubricating oil and increase the sealing performance. When replacing the tractor's oil, thoroughly clean the oil filter, the filter, and the oil pan. The diesel engine equipped with a transfer switch should be turned to the "summer" position in the summer so that the engine oil can enter the main oil passage after being cooled, so as to prevent the viscosity of the lubricant from decreasing.
(e) Correct use of batteries.
In the summer, a part of the electrolyte in the tractor battery should be sucked out, and an appropriate amount of distilled water should be added to control the specific gravity of the electrolyte to about 1.25. The liquid level should be checked every 5 to 10 days (normal liquid level should be higher Plate 10--15mm. Distilled water is added when it is insufficient. The battery should always maintain sufficient power. When the tractor is not working for a long time, the battery should be removed and placed in a ventilated, dry room, charged once every 15 - 20 days. In addition, keep the outside of the battery clean.
(6) Reasonable use and storage.
In summer, the best time for the tractor to work is in the morning and evening. Try not to leave the car at noon. The load of normal operation should be controlled at about 85% to avoid overload operation. It is best to park the tractor in the garage at night, and cover it with plastic sheeting when storing in the open air.
