Compatibility

Cleaning and Care
- Strain every fill. Strain the coating into the cup so debris doesn't reach the nozzle.
- Empty and wipe. After spraying, pour out what's left and wipe the cup and lid with a cleaner-soaked rag.
- Flush the gun. Put some cleaner in the cup, then spray it through until it runs clean.
- Clean the fluid tube. Check the siphon tube for dried coating and clean it before it hardens.
- Check the lid seal. If the lid doesn't seal, Fuji says to change the 6331 cup gasket. They come in a 5-pack.
- Replace the diaphragm. Swap in a new 6332 diaphragm when the old one is worn or swollen.

How do I clean it?
Empty it, wipe the cup and lid with a cleaner-soaked rag, flush cleaner through the gun, and clear the siphon tube before coating dries in it.
