3. Setup

1. Unpack Components: Carefully remove all parts from the packaging. Verify that all components listed in the 'Content of the Set' section are present.
2. Assemble Lance: Connect the fiberglass lance sections if they are separate, then attach the adjustable nozzle to the end of the lance.
3. Connect Hose: Securely attach the reinforced hose to the sprayer tank and the lance handle.
4. Attach Shoulder Strap: Fasten the shoulder strap to the designated attachment points on the sprayer tank for comfortable carrying during use.

4. Operating Instructions

4.1 Filling the Tank

1. Unscrew the pump assembly from the top of the tank.
2. Using the provided cup for dispensing liquids, carefully pour the desired liquid (water, fertilizer, pesticide) into the cylinder. Do not exceed the 5L capacity or the maximum fill line indicated on the tank.
3. Screw the pump assembly back onto the tank tightly to ensure a sealed system.

4.2 Building Pressure

1. With the pump assembly securely closed, pump the handle up and down repeatedly to build air pressure inside the tank.
2. Continue pumping until you feel significant resistance or observe the pressure gauge (if present) reaching the optimal operating pressure (up to 3.2 Bar).

4.3 Adjusting the Nozzle and Spraying

1. Point the nozzle away from yourself and others.
2. Rotate the adjustable nozzle to select the desired spray pattern, from a fine mist for delicate plants to a strong stream for targeted application.
3. Press the trigger on the lance handle to begin spraying. The trigger can often be locked for continuous spraying.
4. Use the shoulder strap to comfortably carry the sprayer, allowing for easy movement and reaching higher plants with the 81 cm lance extension.

5. Maintenance

1. Cleaning After Use: After each use, especially when using chemicals, thoroughly rinse the tank, hose, and nozzle with clean water. Pump clean water through the system to clear any residue.
2. Gasket Inspection: Regularly inspect all gaskets and O-rings for wear or damage. Replace them with the additional set of gaskets provided if necessary to maintain a proper seal and pressure.
3. Nozzle Cleaning: If the nozzle becomes clogged, unscrew it and clean any debris. A small brush or needle can be used carefully.
4. Storage: Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures. Release any remaining pressure before storage.

6. Troubleshooting

• No Pressure or Low Pressure:
  • Ensure the pump assembly is screwed on tightly.
  • Check all hose connections for leaks.
  • Inspect gaskets and O-rings for wear or damage and replace if needed.
  • Ensure the tank is not overfilled, which can reduce air space for pressure build-up.
• Uneven or Blocked Spray:
  • Clean the nozzle as described in the Maintenance section.
  • Check the lance and hose for any kinks or blockages.
• Liquid Leaking:
  • Tighten all connections, including the pump assembly and hose fittings.
  • Replace any worn or damaged gaskets.

7. User Tips

• Pre-mix Solutions: For best results and to prevent clogging, pre-mix any concentrated solutions in a separate container before pouring them into the sprayer tank.
• Test Spray: Always test the spray pattern and pressure on an inconspicuous area before applying to your main plants.
• Wear Protective Gear: When using chemicals, always wear appropriate personal protective equipment, including gloves, eye protection, and a mask.
• Regular Cleaning: Consistent cleaning after each use significantly extends the lifespan of your sprayer and prevents cross-contamination between different solutions.
• Don't Over-pressurize: While the sprayer can handle up to 3.2 Bar, avoid excessive pumping beyond what is needed for your task, as this can strain components.
