FAQ
Q1: Is this spray gun compatible with my backpack sprayer?
A: Most backpack sprayers use standard 1/4" or 3/8" hose connections. Check your existing spray gun's hose barb size or thread type. Use an adapter if needed for proper fit.
Q2: What is the difference between stainless steel and aluminum lances?
A: Stainless steel lances are heavier but more durable and corrosion-resistant. Aluminum lances are lighter but may bend under heavy use. Both work well for backpack sprayer applications.
Q3: How do I maintain my backpack sprayer spray gun?
A: After each use, flush with clean water to remove chemical residue. Check washers and O-rings for wear annually. Lubricate trigger pivot points with silicone spray if stiff. Replace if trigger leaks or nozzle no longer adjusts properly.
