Operating Instructions
Follow these steps for effective operation:
- Prepare the Solution: Mix your desired liquid (e.g., weed killer, fertilizer) according to its instructions in a separate container.
- Fill the Tank: Unscrew the tank lid and carefully pour the prepared solution into the tank. Use the integrated filter screen to prevent debris from entering the tank. Do not exceed the 16L capacity.
- Secure the Lid: Tightly screw the tank lid back on, ensuring a proper seal.
- Pressurize the Tank: Place the sprayer on your back using the carrying straps. Use the pumping handle to pump air into the tank. Pump until you feel resistance, indicating sufficient pressure (1 to 3 bar working pressure).
- Begin Spraying: Point the nozzle towards the target area and press the trigger on the spray handle to release the spray. Adjust the nozzle for desired spray pattern (fine mist to direct stream).
- Maintain Pressure: Periodically pump the handle during operation to maintain consistent spray pressure.
- Release Pressure: After use, release any remaining pressure in the tank by holding the trigger open until no more liquid or air is expelled.

- Check Seals and O-rings: Regularly inspect all seals and O-rings for wear or damage. Replace them if necessary using the provided spare parts to maintain a good seal and pressure.
