1 Rolling back and forth is counted as one time. When rolling the subgrade, complete one compaction, at least twice each time.
2 Operating rules: During operation, the road roller should start before it starts to vibrate, and the internal combustion engine should be set to medium speed first, and then adjusted to high speed.
3 Stop the engine first when shifting and reversing, and reduce the speed of the internal combustion engine when shifting.
4 It is strictly forbidden for the roller to vibrate on solid ground.
5 When rolling the soft subgrade, it should be rolled 1-2 times without vibration, and then vibrated.
6 When rolling, the vibration frequency should be consistent. For adjustable vibratory rollers, the vibration frequency should be adjusted first before the operation, and the vibration frequency should not be adjusted without shaking.
7 The adjustment of the reversing clutch, shock clutch, and brake should be carried out after the main clutch is disengaged.
8 When going up or downhill, the fast gear cannot be used. When making sharp turns, including articulated vibratory rollers rolling in small turns, it is strictly forbidden to use fast gears.
9 The road roller must not engage in vibration when driving at high speed.
