4. Operating Instructions
4.1 Paint Preparation and Refilling
- Always dilute paint according to the manufacturer's instructions and test viscosity using the included viscosity cup. Proper dilution is crucial for optimal spray performance and to prevent clogging.
- Use the convenient side-fill port to add paint to the 1200mL tank without disassembling the entire unit. This minimizes mess and speeds up refills.
