🎯 **Performance Issues**

• Poor atomization quality
• Uneven spray patterns
• Splotchy or inconsistent lines
• Reduced paint flow control

🔧 **Physical Problems**

• Visible damage to nozzle opening
• O-ring deterioration or loss
• Thread damage from over-tightening
• Paint leaks or air pressure loss

✅ **DO These Steps**

1. Clean the airbrush body thoroughly before installation
2. Check the O-ring is properly seated and undamaged
3. Thread in by hand - start gently to avoid cross-threading
4. Tighten finger-tight only - feel for proper seating
5. Test spray pattern with water before using paint

❌ **NEVER Do This**

1. Use pliers or wrenches - this will damage threads
2. Over-tighten - you'll break the O-ring or threads
3. Force installation - if it doesn't go easily, stop
4. Use steel picks to clean - this damages the precision opening
5. Install without O-ring - it will leak immediately

🔍 **Cleaning Guidelines**

• Clean gently - no steel wire brushes
• Use appropriate airbrush cleaners only
• Don't let paint dry in the nozzle opening
• Soak in cleaner if paint has dried

⚙️ **Performance Checks**

• Inspect O-ring for damage before each use
• Test atomization with water first
• Check for even spray patterns
• Monitor for any air or paint leaks

🤔 **Does this nozzle fit every Neo model?**

Answer: No, this fits ONLY Neo CN (gravity feed, 0.35mm). It's NOT compatible with Neo BCN (bottom feed, 0.5mm).

🔧 **Do I need special tools for installation?**

Answer: No tools needed! Thread it in by hand with a gentle touch. Over-tightening damages the threads or tears the O-ring.

🎯 **Should I replace the needle at the same time?**

Answer: Replace both if the needle is excessively worn or bent. In practice, a new nozzle often restores full performance if the needle isn't damaged.

💍 **Is the O-ring included and fitted?**

Answer: Yes! Factory pre-installed - no fiddly assembly of tiny seals. Ready to install straight from the package.
