5. Operating Instructions
- Prepare Solution: Mix your desired liquid solution (water, fertilizer, herbicide, etc.) according to the manufacturer's instructions in a separate container.
- Fill Tank: Unscrew the tank cap and carefully pour the prepared solution into the 16-liter tank. Do not overfill.
- Secure Cap: Tightly screw the tank cap back on to ensure a proper seal.
- Pressurize 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.
- Adjust Nozzle: Rotate the adjustable nozzle to select your desired spray pattern (jet for targeted application, mist for broader coverage).
- Begin Spraying: Aim the lance at the target area and press the Y-trigger handle to release the spray. Maintain consistent pumping to sustain pressure during operation.
- Depressurize: After use, or if you need to open the tank, always depressurize the sprayer by pulling the safety valve until all air escapes.
- Empty and Clean: Empty any remaining solution and thoroughly clean the tank, hose, and lance as described in the Maintenance section.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sprayer.
- After Each Use:
- Empty any remaining solution from the tank.
- Rinse the tank thoroughly with clean water. Pump clean water through the hose and lance until all chemical residue is flushed out.
- Clean the nozzle to prevent blockages. If necessary, disassemble and clean with a small brush.
- Wipe down the exterior of the sprayer with a damp cloth.
- Periodic Maintenance:
- Inspect all seals and O-rings for wear or damage. Replace if necessary to prevent leaks.
- Check the hose for cracks or kinks.
- Ensure the safety valve operates freely.
- Lubricate moving parts of the pump assembly with silicone grease if needed.
- Storage: Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures. Ensure it is depressurized and clean before storage.
