When internal servicing is required
Internal servicing may be required when paint leaks behind the fluid section, the needle packing no longer seals correctly, the trigger or needle movement remains abnormal after normal cleaning, or an internal valve or seal requires replacement. The required service depends on the airbrush model and symptom.

Risks of over-disassembly
Unnecessary or incorrect disassembly can damage small threads, lose springs or seals, misalign internal components, or create new air and paint leaks. Disassemble only as far as needed for the maintenance task and keep small components organized.

Product Questions
Why air pressure feels inconsistent
First check the compressor, regulator, hose connections, and air supply for pressure fluctuations or leaks. If the upstream supply is stable but airflow through the airbrush remains inconsistent, inspect the air valve for contamination, sticking, or damage.

Product Questions
How do I adjust the spray setting on the GHAD-68 for finer lines?
Use the 0.38mm setup and start with a relatively low working pressure, such as around 15–20 PSI. Use a light, controlled trigger pull and work closer to the surface while maintaining steady movement. Proper paint viscosity and a clean needle/nozzle are also important for fine-line control.

Product Questions
What can I do if the trigger on my GHAD-68 feels stiff or unresponsive?
If the trigger feels stiff or unresponsive, inspect the trigger, slider, and spring mechanism for dried paint or debris. Clean the components and apply a small amount of airbrush-specific lubricant to the slider as shown in the GHAD-68 manual. Make sure all parts are correctly reassembled before testing again
