Adjust the pressure of the impact system steplessly, the strike energy of the hammer will also shift steplessly. When the pressure is higher, the strike energy is higher. When the pressure is lower, the strike energy is lower. Adjust the oil flow of supply pump steplessly, the strike frequency will also shift steplessly. When the flow is more, the strike frequency is higher. When the flow is less, the strike frequency is lower.
