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

Product Questions
Why does my GHAD-68 airbrush have inconsistent spraying or overspray?
Check the working pressure, spraying distance, paint viscosity, and needle/nozzle cleanliness first. Also make sure the needle chucking nut is secure so the needle responds correctly to trigger movement. Excessive pressure or spraying too far from the surface can increase overspray.

Product Questions
What should I do if GHAD-68 air comes out but no paint?
If air flows but no paint sprays, first confirm that the needle moves correctly as the trigger is pulled. Then check the nozzle and fluid passage for blockage, verify that the 0.38mm or 0.5mm needle/nozzle components are correctly matched, and make sure the paint viscosity is appropriate for the setup.
