Take care to prevent the engine temperature from being too high. In most cases, the water tank is short of water. In this case, cooling water may not be added immediately, causing the cylinder head or the cylinder to burst and injuring people. The correct way is to stop the operation, run at low speed until the water temperature drops to about 70C, and then slowly add clean cooling water.
Take care to prevent the engine tank from being over-scaled. If the engine water jacket is too thick, the heat dissipation efficiency will be reduced by 30% to 40%, which may cause the engine to overheat and the power to decrease. Therefore, the scale must be regularly cleaned to maintain good cooling performance.
Take precautions to prevent air locks in the fuel system. Once the fuel produces air resistance, it should immediately stop cooling, and pull the hand pump to eliminate air, so that the oil is full of fuel.
Take care to prevent the use of oil. Lubricating oil viscosity varies with the temperature, and the viscosity decreases when the temperature rises. In summer, ECA-30 or ECA-40 diesel engine oils are used.
Take care to prevent looseness of fan tape. Under high temperature operation, the tension of the tape drops, causing the tape to slip, the transmission efficiency to decrease, and the tape being easily damaged. Therefore, in the summer, the tension of the cold-adjusted engine belt is slightly higher than the standard value.
Take care to prevent fire. Always check the fastening of the wires and the fuel pipe fittings to prevent sparks due to poor contact or fuel pipe leakage.
Take care to prevent high tire pressure. As the temperature rises, the air increases in volume and tends to cause tire bursts. Inflating tires in summer should be 5%-7% lower than in winter, and never exceed the standard tire pressure.
Pay attention to prevent the gas brake pipe from generating air resistance. In the summer of high temperature, the oil brake brake pipeline is prone to air resistance, which seriously affects the braking effect. Therefore, in use, one must ensure sufficient brake fluid, and secondly prevent pipeline leakage, and the third must be timely when air resistance occurs. Drain the air.
