Finally, check whether the operating lever of the water cannon is flexible and can be operated normally.

Before using the manual fire water cannon, its spraying direction must be determined. Based on the location of the fire and the size of the fire intensity, select the most appropriate spraying direction. When determining the spraying direction, the surrounding environment and the safety of personnel must be taken into account.

Before using the manual fire water cannon, it is necessary to connect to the water source. Ensure that the pressure and flow rate of the water source are sufficient to meet the usage requirements of the manual fire water cannon.

Before using the manual fire water cannon, its spraying angle and water flow rate must be adjusted. According to the location of the fire and the size of the fire intensity, adjust the spraying angle and water flow rate to achieve the best fire extinguishing effect. When adjusting the spraying angle and water flow rate, pay attention to the surrounding environment and the safety of personnel.

After completing the above steps, the manual fire water cannon can be used for spraying. When spraying, maintain a stable posture and control the spraying direction and water flow rate of the water cannon to achieve the best fire extinguishing effect. During the spraying process, always be aware of the surrounding environment and the safety of personnel.
