Operating Instructions
- Prepare the Solution: Mix your desired liquid (water, fertilizer, cleaning agent) according to its instructions. Do not exceed the 16L capacity of the tank.
- Fill the Tank: Unscrew the tank lid and carefully pour the prepared solution into the tank. Use a funnel if necessary to prevent spills. Securely fasten the lid.
- Pressurize the Sprayer: Place the sprayer on your back using the shoulder straps. Operate the pump handle repeatedly to build pressure inside the tank. You will feel resistance as pressure builds.
- Begin Spraying: Squeeze the trigger on the spray wand handle to release the spray.
- Adjust Spray Pattern: Rotate the nozzle at the end of the spray wand to adjust the spray pattern from a fine mist to a direct stream, depending on your application needs.
- Maintain Pressure: Periodically pump the handle during operation to maintain consistent spray pressure.
- Depressurize After Use: After use, release any remaining pressure in the tank by holding the spray trigger until no more liquid or air is expelled.
Maintenance
- Cleaning: After each use, especially when using chemicals, rinse the tank thoroughly with clean water. Pump clean water through the hose and spray wand to flush out any residue.
- Nozzle Cleaning: If the nozzle becomes clogged, remove it and clean it with water. A small brush or pin can be used to clear blockages.
- Storage: Store the sprayer in a dry, frost-free location, away from direct sunlight. Ensure the tank is empty and clean before storage.
- Seals and O-rings: Periodically inspect seals and O-rings for wear and tear. Replace them if they appear damaged to prevent leaks.
