3. Setup

1. Unpack Components: Carefully remove all parts from the packaging. Verify that all components listed in Section 2 are present.
2. Attach Hose and Lance: Connect the PVC hose to the sprayer's outlet and securely attach the brass lance to the other end of the hose. Ensure all connections are tight to prevent leaks.
3. Install Nozzle: Select the desired nozzle (jet-cone or fan) and screw it onto the end of the lance.
4. Adjust Straps: Place the sprayer on your back and adjust the shoulder straps for a comfortable and secure fit. The sprayer should sit evenly on your back.
5. Prepare Solution: Before filling, ensure the tank is clean. Mix your desired solution according to the manufacturer's instructions in a separate container.
6. Fill Tank: Unscrew the tank lid and carefully pour the prepared solution into the wide mouth of the translucent tank. Do not overfill beyond the maximum capacity mark (15 liters).
7. Secure Lid: Tightly screw the tank lid back on to prevent leaks and maintain pressure.

4. Operation

1. Build Pressure: With the tank filled and lid secured, operate the pumping handle on the side of the sprayer. Pump the handle repeatedly until you feel resistance, indicating sufficient pressure has built up inside the tank.
2. Test Spray: Point the lance away from people, animals, and desired plants. Press the trigger on the lance handle to release the spray. Observe the spray pattern.
3. Adjust Nozzle: If using the adjustable jet-cone nozzle, rotate the nozzle tip to change the spray pattern from a fine mist to a direct stream. The fan nozzle provides a wider, even spray.
4. Apply Solution: Walk at a steady pace, maintaining consistent pressure by periodically pumping the handle. Apply the solution evenly to the target area.
5. Release Pressure: After use, or before opening the tank, always release any remaining pressure. This can typically be done by holding the trigger until no more solution is expelled, or by carefully loosening the tank lid (while pointing away from your face) until the hissing sound stops.

Note: The mechanical agitator inside the tank will help keep your solution mixed as you pump, ensuring consistent application.

5. Maintenance

5.1 Cleaning After Use

1. Empty Tank: After each use, empty any remaining solution from the tank. Dispose of chemical residues according to local regulations.
2. Rinse Tank: Fill the tank with clean water and pump it through the sprayer until the water runs clear. Repeat this process several times to ensure all chemical residues are removed from the tank, hose, and lance.
3. Clean Nozzles: Remove the nozzle(s) and rinse them thoroughly with clean water. If clogged, use a soft brush or a thin wire to clear any obstructions. Do not use metal objects that could damage the nozzle orifice.
4. Wipe Exterior: Wipe down the exterior of the sprayer with a damp cloth.

5.2 Storage

• Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures.
• Ensure the tank is completely empty and clean before storage.
• Keep the sprayer out of reach of children and pets.
• Do not store with pressure in the tank.
