Important Safety Information

Read and understand all safety warnings before operating this sprayer. Failure to follow these instructions may result in serious injury or property damage.

• Always wear safety goggles, gloves, and protective clothing when using the sprayer.
• Read and follow all instructions and cautions on the labels of products used in this sprayer.
• Never use flammable liquids, caustics, acids, or hot water in this tank.
• Do not leave the sprayer in direct sunlight when not in use.
• Spray when the air is calm to prevent chemical drift.
• Do not use the sprayer near open flames or anything that could ignite the spray.
• Inspect the hose and all connections before each use. A damaged hose or loose connection can lead to chemical exposure.
• Do not lift or carry the sprayer by the hose, shut-off valve, or wand extension. Carry it only by the pump handle, ensuring it is properly locked.
• Do not pressurize with mechanical devices like air compressors, as this can cause dangerous pressure levels and bursting. Only use the original pump.
• Do not store chemicals in the tank.
• Always release pressure when the sprayer is not in use and before removing the pump from the tank.
• Do not stand with your face or body over the tank when pumping or loosening the pump to prevent solution from striking you.
• Clean and rinse the sprayer thoroughly after each use.
• Never attempt to alter the sprayer from its original condition.
• Always use replacement parts from the original manufacturer.

Setup and Assembly

The Roundup 190260 sprayer features an easy one-step assembly process. Follow these steps to prepare your sprayer for use:

1. Attach the Hose and Wand: Connect the hose to the tank and the wand to the hose. Ensure all connections are secure to prevent leaks.
2. Select and Attach Nozzle: The sprayer includes three different nozzles: a poly adjustable nozzle (for solid stream to fine mist), a high-volume flat fan nozzle, and a low-volume flat fan nozzle. Choose the appropriate nozzle for your application and screw it onto the end of the wand.
3. Secure the Pump Assembly: The pump assembly features a new lock mechanism. To secure it, push down on the pump handle and twist it 90 degrees until it locks firmly into place.

For optimal performance, ensure all components are tightly connected before filling the tank.

Operating Instructions

Once assembled, operating your sprayer is straightforward:

1. Fill the Tank: Unscrew the pump assembly by twisting it 90 degrees counter-clockwise and lifting it out. Carefully pour your desired liquid (weed killer, insect control, cleaning solution, or water) into the 2-gallon tank. Do not overfill. If using concentrates, follow the product's mixing instructions carefully.
2. Secure the Pump: Reinsert the pump assembly and twist it 90 degrees clockwise to lock it securely.
3. Pressurize the Sprayer: Pump the handle up and down repeatedly until resistance is felt and the tank is pressurized. The efficient pump requires fewer strokes to achieve pressure.
4. Begin Spraying: Aim the wand at the target area. Squeeze the comfort grip shut-off handle to begin spraying. For continuous spraying, push the lock mechanism on the handle.
5. Adjust Spray Pattern: Rotate the adjustable nozzle to change the spray pattern from a fine mist to a solid stream, or utilize the flat fan nozzles for broader coverage. The wand also swivels for spraying under leaves or in hard-to-reach areas.
6. Release Pressure: When finished spraying or before refilling, safely release the pressure using the pressure release cap. This cap is designed to send vapors and liquids down and away from you.

Maintenance

Proper maintenance ensures the longevity and effective performance of your sprayer:

• After Each Use: Thoroughly clean and rinse the sprayer. Fill the tank with plain hot water and spray until the tank is empty to clear the hose and nozzle, preventing clogging.
• Storage: Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures. Ensure all pressure is released before storage.
• Inspection: Periodically inspect the hose, seals, and nozzles for any signs of wear, cracks, or damage. Replace any worn parts with genuine Roundup replacement parts.

Troubleshooting

If you encounter issues with your sprayer, refer to the following common problems and solutions:

• No Spray or Weak Spray:
  • Check if the tank is sufficiently pressurized. Pump the handle several times.
  • Inspect the nozzle for clogs. Clean or replace if necessary.
  • Ensure all hose connections are tight and there are no leaks.
  • Verify the pump assembly is securely locked into the tank.
• Leaking:
  • Tighten all connections, including the hose to the tank, the wand to the hose, and the nozzle to the wand.
  • Check the O-rings and seals on the pump assembly and connections for damage. Replace if worn or cracked.
• Difficulty Pumping:
  • Ensure the pump assembly is properly seated and locked.
  • Check for any obstructions in the pump mechanism.
• Sprayer Not Holding Pressure:
  • Check the pressure release cap to ensure it is fully closed.
  • Inspect the pump's O-rings and seals for wear or damage.
