Bulldozer inspection and maintenance

Check whether the joints, oil cylinders, floating oil seals, radiator fins, water pipe joints, etc. of the high-pressure pipes are leaking. If so, eliminate them in time. Check whether the electrical system has broken wires, short wires, and loose terminals. If so, eliminate them in time. Check the oil level in the engine oil pan: When the engine is stopped, first confirm whether the engine oil pressure gauge and water temperature gauge are within the normal range, then take out the oil dipstick to check whether the liquid level should be between the upper and lower scale lines of the oil dipstick. If you need to add engine oil, open the oil filling port and add it. When checking the oil level, the vehicle should be parked on a level ground. When adding engine oil, the oil level should not be higher than the "H" mark.
