Quick guide from the manual

This manual provides instructions for the assembly, operation, and maintenance of the Master 50 Gallon UTV Sprayer. Key requirements include using fresh water to test for leaks before adding chemicals, wearing appropriate personal protective equipment (PPE), and never using flammable or corrosive chemicals (such as bleach or diesel) which can damage the unit and void the warranty.

The assembly process requires a 1/2 inch socket wrench, pliers, and Teflon tape. Ensure all components are inspected upon arrival.

• Drain Assembly: Press the drain cap gasket into the cap, attach the tether, and thread onto the tank drain outlet.
• Tank Setup: Thread the tank lid onto the tank.
• Spray Gun Bracket: Attach the bracket to the tank using the provided 1/2 inch bolts.

• Boom Mounting: Insert boom mounting arms into the tank handle slots. Secure with 3.5 inch bolts, wing nuts, and hex nuts. Attach boom mounting brackets using square U-bolts.
• Final Connections: Connect the boom inlet hose to the shut-off valve. Connect the wire harness to the pump and the vehicle battery (red to positive, black to negative). Attach the boom assembly to the mounting brackets.

Safety Information

Safety is paramount when handling pesticides. Always follow these guidelines:

• Operator Age: Must be 16 years or older.
• Wind Conditions: Do not spray if wind speed exceeds 4 MPH to prevent drift.
• Chemical Handling: Always read and follow the chemical manufacturer's label. Never eat, drink, or smoke while handling chemicals.
• Emergency: In case of spills or exposure, follow the first aid instructions on the chemical label.

Operation

Before each use, inspect the sprayer for cracks or leaks and test with fresh water. Ensure the drain cap is tight.

• Spot Spraying: Pull the gun trigger and point the nozzle at the target vegetation. Twist the nozzle to adjust the spray pattern.
• Broadcast Spraying: Open the boom valve to allow flow. Ensure the boom nozzle is pointed straight down. Turn the remote switch to the ON position to begin.

Cleaning and Storage

Proper maintenance prevents damage and ensures longevity.

• Cleaning: Drain excess pesticide into a suitable container. Flush the system with fresh water. Decontaminate yourself and wash clothing separately.
• Winterization: To prevent freezing damage, run one gallon of RV anti-freeze through the system. Drain the anti-freeze before storing.

Troubleshooting

If the pump fails to operate, check the battery connections, fuse, and voltage. If the pump runs but does not prime, check for air leaks in the inlet or obstructions in the tubes. Always relieve system pressure before attempting repairs.
