Note: 1. Do not use the sprayer in a closed space. After spraying, the doors and windows can be closed to improve the construction effect and protect human health. 2. When cleaning the exterior of the machine with water or other neutral detergent, please make sure that no water or neutral detergent enters the motor housing. 3. After each use, the unused liquid must be poured out. Be careful not to pollute the environment. In addition, add water to the medicine box and spray for about 0.5 to 1 minute to clean the machine tube so that the liquid will not corrode the machine and prolong the service life of the machine. This is very important and necessary. 4. It is forbidden to bake for a long time under high temperature or sunlight, deform, fade or crack.
