Usage Notes

• Ensure your sprayer can support a 10 mm tip — check the fluid section and pump pressure ratings.
• Flush the nozzle thoroughly before first use to clear any debris.
• Use proper spray pressure and angle to maintain an even fan and avoid thin spots or splatter.
• Clean the nozzle after each use, especially when using textured or thick materials, to prevent clogging.
• Inspect the orifice periodically for wear — large nozzles can wear faster under abrasive materials.
