1,When rolling on newly opened roads, it should be done from the middle to both sides, and the rolling should not be too close to the edge of the roadbed to prevent collapse.
2,When going uphill or downhill, the gear should be selected in advance, and shifting or sliding on the slope is prohibited.
3,When building roads in mountainous areas, it is necessary to roll from the inner side to the outer side. When rolling the second row, it is necessary to overlap the length of more than half a wheel.
4. It is prohibited to use traction to forcibly start the internal combustion engine, and do not use a roller to tow other machinery or objects.
5. The scraper plates of the front and rear rollers should be regularly inspected and cleaned to maintain their flatness and good function.
6. If the roller of the road roller needs to be filled with yellow sand to increase weight, dry yellow sand should be used; Do not use water to increase weight in winter to prevent the roller from freezing and cracking.
7. If the newly filled roadbed is soft, it must be compacted layer by layer with a sheep foot roller or a compactor before being compacted with a road roller.
When two or more road rollers are driving or rolling on a flat road, the distance between them should be maintained at least 3 meters. It is prohibited to drive in groups or slide on slopes to avoid accidents.
When a mechanical malfunction requires maintenance, the engine must be turned off, the brake must be applied, and the rollers must be symmetrically wedged with a triangular wooden block.
When using a rubber tire roller, attention should be paid to maintaining the normal tire pressure and whether there are stones sandwiched between the tires.
11. Road rollers should be parked in areas that do not affect traffic, on flat ground, and not on slopes. If it is necessary to park on a slope, wooden stakes must be driven in advance to prevent slipping. When parking overnight in winter, it is necessary to use wooden boards to cushion the rollers off the ground to prevent them from freezing together with the ground.
12. Vibration rollers are strictly prohibited from vibrating on solid roads to prevent damage to the components.
13. The starting or stopping vibration of the vibrating roller should be carried out during driving to avoid damaging the smoothness of the road surface being compacted.
