(1) Check whether the screws of each part of the automatic mist sprayer machine are loose or fall off.

(2) Open the lower cover of the handle, put the battery into the cavity of the handle, and then fasten the lower cover. Pay attention to the positive and negative poles of the battery. The positive direction is towards the head side.

(3) Trial operation. Remove the nozzle cap of the automatic mist sprayer machine. It is forbidden to energize the motor with the nozzle cap, otherwise the teeth of the toothed disc will be damaged. After closing the switch of the sprayer, observe whether the motor (see the atomizing disc) is running normally and whether the circuit is smooth.

(4) Pour the medicine liquid into the medicine bottle after filtering, and tighten it on the medicine bottle support, but do not screw it too tightly, so as not to damage the bottle mouth or the support. At this time, the position of the bottle mouth should be upward.

(5) Correctly measure the flow rate of the automatic mist sprayer machine liquid.
