1. The asphalt pump and pipeline must be cleaned when the distributor completes one operation or changes the construction site, otherwise it will not work next time. 2. Before spraying, the distributor must check whether the valve positions are correct. The hot bitumen added into the bitumen tank must reach a working temperature of 160~180℃. For long-distance transportation or working time is too long, a heating device can be used for heat preservation, but it cannot be used as an oil melting furnace. 3. The asphalt tank cannot be filled too full, and the fuel filler cap must be closed tightly to prevent the asphalt from overflowing during transportation. 4. When using a burner to heat the pitch in the tank, the pitch height must exceed the upper plane of the combustion chamber, otherwise the combustion chamber will be burned out. 5. If the asphalt pump and pipeline are blocked by the solidified asphalt, the pump cannot be forced to rotate, but a blowtorch can be used for baking. Avoid directly baking the ball valve and rubber parts. 6. When spraying asphalt at the beginning, start slowly and keep the car running at a low speed. Do not slam on the accelerator to prevent damage to the clutch, asphalt pump and other components. 7. After the daily operation is completed, if there is any remaining asphalt, it must be returned to the asphalt pool, otherwise it will not work next time if it solidifies in the tank. If the car or working device fails, it is determined that it cannot be repaired in a short time, and the asphalt in the tank must be drained.
