V. Operating Instructions

1. Preparing the Solution: Filter the prepared chemical solution before pouring it into the tank. Secure the lid tightly to prevent leaks during pressurization.

2. Wearing the Sprayer: Place the sprayer on your back and adjust the straps for a comfortable fit.

3. Pressurization: Repeatedly pump the manual handle to build pressure inside the tank. Once sufficient pressure is reached, press the trigger on the spray wand to begin spraying.

4. Adjusting the Nozzle: Rotate the nozzle to switch between mist and stream spray patterns as needed.

5. After Use: Empty any remaining solution. Thoroughly rinse the tank, wand, and nozzle with clean water. Allow the equipment to air-dry before storage to prevent residual chemicals from corroding the components.

VI. Safety Precautions

When using pesticides, always wear full protective gear-including a mask, goggles, gloves, and protective clothing-and strictly follow safety protocols for handling chemicals.

Do not use highly corrosive liquids, as these can damage the tank and internal tubing.

Avoid spraying against the wind to prevent inhaling chemicals or getting them on your skin.

Store in a cool, dry place. Avoid prolonged exposure to direct sunlight, which can accelerate the aging of the tank material. Children are strictly prohibited from operating this device; keep it out of their reach when storing.

Always clean the device after each use; pesticide residues can easily clog the nozzle and corrode the internal pump mechanism.
