Ask the above three models of the driver's job responsibilities, to be specific, not general. I will add additional points
11, rolling on the new road should be rolled from the middle to the sides, and the edge shall be no less than 0.5m when it is rolled. 12, rolling adjacent to the mountain road, should be side to side rolling, from the edge of the roadbed should not be less than 1m. 13, on the downhill, should be selected in advance gear, not on the slope shift, downhill may not neutral sliding. 14, two or more rollers at the same time work, the distance between the front and rear shall not be less than 3m, on the ramp may not column driving. 15, in the operation shall be repaired or fuel, repairs on the bottom of the machine when the engine flameout, with brake and rolling blade large live wheel feng. 16. For a three wheeled roller with differential locking device, a differential locking device is used only when one wheel is slipping, but no turning is allowed. 17. After work, park the roller in a flat and solid place and brake. Shall not be parked on the edge of the dirt road or on the slope, nor shall it be parked where traffic is disturbed. 18, cold season should be stopped when the roller with wooden mats from the ground 19, roller transfer site from a distance, should use the car or flatbed trailer shipment, shall not be used by other vehicles drag and haul. Vibratory roller 1, when operating, roller should start before vibration, the internal combustion engine should be placed in the medium speed, and then tune
The working surface static roller and 1 roller should be properly smooth, to fill the soft subgrade should first use ramming machine roller by kneading or rolled or compacted layer behind the available road. 2, when the soil moisture content of more than 30% may not be rolled, water content less than 5%, appropriate watering. 3, the longitudinal slope of the work area should not exceed the maximum climbing capacity of the roller, the transverse slope should not be greater than 200. 4, the machine weight should be selected according to the rolling requirements. When a roller machine may need to increase the weight inside the roller sand or water. When the temperature drops to 0 degrees centigrade, the weight shall not be increased by water 5, and the tyre roller shall not be operated on the big stone foundation. 6, before the operation of pipeline and fittings of each system should be free of cracks and loose leakage phenomenon, the scraper roller should be smooth, not loose fasteners, tire roller should also check the tire pressure, to confirm the normal before start. 7. The internal combustion engine shall not be forced to be pulled by traction, nor shall any mechanical or object be hauled by the rollers. 8. After starting, test operation should be carried out. It is confirmed that the operation is normal, the braking and steering functions are sensitive and reliable, and the operation can be done. No obstructions or personnel around the roller should be operated. 9, rolling should be low speed, variable speed must stop.
