Fire water gun operation procedures and precautions
1 Before connecting, the chute and sealing parts should be carefully checked. If there are impurities such as sludge and sand particles, they must be removed in time to prevent difficult assembly and disassembly and poor sealing.
2 When operating the DC water gun to shoot water, the influence of the reaction force must be taken into consideration. When changing the direction of the water jet, operate as slowly as possible. The rotary switch should be carried out slowly when switching functions.
3 In the process of use, if you want to change the function, you can achieve it by rotating the switch. From the inlet of the water gun, turning to the left turns on the spray function. Turning to the end, the spray angle is adjusted to a large value; turning right to DC Function, turn to the top to turn off the water gun.
4 The effective range of the DC water gun during firefighting can be determined according to the specific conditions of the fire site such as the fire hazard category and radiation size. The increase of the effective range of the DC water gun is limited, and its working pressure should not exceed 0.70MPa.
5 When using a water spray gun to extinguish fires of live equipment, be sure to ensure a safe distance. When the voltage is less than 33000 volts, the safe distance is not less than 2m.
