Setup

Unpacking and Assembly

Carefully remove all components from the packaging. Ensure all parts are present before proceeding with assembly. The Solo 419 comes largely pre-assembled, requiring minimal setup.

1. Inspect Components: Check for any damage during shipping. Verify that the main sprayer body, pump assembly, wand, and nozzle are intact.
2. Attach Wand (if detached): If the 9.5-inch metal wand is separate, securely screw it into the designated port on the sprayer handle. Ensure a tight fit to prevent leaks.
3. Nozzle Adjustment: The multi-directional nozzle can be adjusted for various spray patterns. Familiarize yourself with its rotation and how it changes the spray.

Filling the Sprayer

Before filling, ensure the sprayer is on a stable, level surface. Always wear appropriate personal protective equipment (PPE) such as gloves and eye protection when handling chemicals.

1. Depressurize: If the sprayer has residual pressure, activate the pressure relief valve to release it.
2. Unscrew Pump Assembly: Twist the pump handle counter-clockwise to unscrew and remove the entire pump assembly from the tank.
3. Prepare Solution: Mix your desired liquid (fertilizer, herbicide, water, etc.) according to the manufacturer's instructions in a separate container if necessary, or directly in the sprayer tank if appropriate. The large opening facilitates easy pouring.
4. Fill Tank: Carefully pour the prepared solution into the sprayer tank. Do not fill above the maximum fill line (2 liters) to allow for adequate air space for pressurization.
5. Re-attach Pump Assembly: Carefully insert the pump assembly back into the tank opening. Screw it clockwise until it is securely tightened. Ensure the pump is seated correctly to create an airtight seal.

Operating Instructions

Pressurizing the Sprayer

To build pressure within the tank, pump the handle up and down approximately 20-30 times until resistance is felt. The pressure relief valve will activate if over-pressurized.

Pump the handle to build pressure in the tank. The enlarged curved handle provides a comfortable grip.

Spraying

1. Aim Nozzle: Direct the nozzle towards the target area.
2. Activate Trigger: Squeeze the trigger on the handle to begin spraying. For continuous spraying, push the red locking tab forward while the trigger is depressed. Release the tab to stop.
3. Adjust Spray Pattern: Rotate the nozzle tip to change the spray pattern from a fine mist to a straight stream. The multi-directional nozzle allows for spraying from various angles, including the underside of leaves.
4. Maintain Pressure: As you spray, the pressure in the tank will decrease. Pump the handle periodically to maintain consistent spray pressure.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your Solo 419 sprayer.

After Each Use

1. Empty Tank: Always empty any remaining liquid from the tank. Do not store chemicals in the sprayer.
2. Rinse Thoroughly: Fill the tank with clean water and pump to spray through the wand and nozzle. Repeat this process several times until the water sprayed is clear. This flushes out chemical residues.
3. Clean Exterior: Wipe down the exterior of the sprayer with a damp cloth.
4. Depressurize: Release all pressure from the tank using the pressure relief valve.
5. Store Properly: Store the sprayer in a cool, dry, and shaded place, away from direct sunlight and freezing temperatures.

Periodic Maintenance

• Check Seals and O-Rings: Periodically inspect the Viton seals and O-rings for wear or damage. Replace them if they appear cracked, brittle, or are causing leaks.
• Clean Nozzle: If the spray pattern becomes irregular or clogged, remove the nozzle and clean it with a soft brush and water. Do not use metal objects that could damage the orifice.
• Lubricate Pump: Apply a small amount of silicone grease to the pump shaft and O-rings to ensure smooth operation and maintain the seal.
