1. Check the road surface before the leveler walks, remove obstacles on the road, keep irrelevant personnel away from the excavator, and then raise the bucket to prepare for starting.

2. Check the direction of the track frame, determine the orientation of the drive wheel, and then honk the horn, and the leveler gradually starts to walk.

3. When the leveler is reversing, it is necessary to estimate the space behind the vehicle in advance. If the blind spot is too large, a special person should be asked to direct and reconcile.

4. The driver controls the walking speed according to the road conditions. When walking on the open flat ground, he can choose "1" gear. The walking speed of the leveler will automatically increase or decrease according to the working pressure of the hydraulic walking circuit; 0" gear, the leveler travels at low speed and high torque.

5. When the screed is walking, try to choose a flat road to avoid rolling of the upper turntable. When walking on bad ground, avoid rocks from damaging the walking motor and crawler frame.

6. When the leveler walks on the ramp, try to move as straight as possible; keep the bucket at an interval of 20-30cm on the ground, and put down the bucket immediately if it encounters slipping and rolling. In the event of stall parking on a ramp, place the bucket on the ground, place the control lever in neutral, and restart the engine.

7. Try to avoid the leveler walking in the water. If wading is necessary, remember to check the water depth and the level of the bottom soft and hard platform in advance. It is not suitable for walking if the underwater silt is too deep or the water surface exceeds the track.

8. It is also necessary to check before the leveling machine starts the engine, for example, check the liquid level of the coolant (add water), check whether the air filter is blocked, check the oil level of the excavator engine, check the hydraulic oil level (add hydraulic oil), check the fuel level of the excavator (add fuel), check whether the horn is normal, check the lubrication of the bucket, check the water and sediment in the oil-water separator, etc.
