What maintenance steps ensure a sprayer remains accurate over time?

• A. Replacing tires and seats on the sprayer.
• B. Regular checks of pump, nozzles, filters, hoses, pressure gauge accuracy, and cleaning.
• C. Painting the tank and labeling.
• D. Only cleaning the exterior.

Answer: (B)

Maintaining sprayer accuracy comes from keeping the system’s key parts in good working order: the pump to provide steady pressure, the nozzles to deliver the intended flow and droplet size, the filters to prevent clogging, the hoses and fittings to avoid leaks, and the pressure gauge to read true pressure. When each of these is functioning well, the spray volume, pattern, and timing stay consistent, which means the product is applied at the correct rate each time. Regular checks and cleaning help prevent drift and under- or over-application. Specifically, inspect nozzle tips for wear and replace as needed, check for clogs and clean or replace filters, look for leaks or cracks in hoses, verify the pressure gauge accuracy against a known reference, and flush or clean lines to remove residue between loads. Calibrating the sprayer by measuring actual output at a known ground speed and adjusting settings ensures the real application rate matches the target. Other activities like painting the tank, labeling, or only cleaning the exterior don’t affect how accurately the sprayer delivers product.
