Trigger: Two stage trigger. Stage one only releases compressed air for blowing off the work piece. Stage two sprays material.
OPERATIONS Tank Regulator The pressure regulator on the paint tank controls the amount of pressure in the paint tank and the spray gun. The following are operating guidelines for internal and external spray guns: Internal Mix Guns: Use higher tank pressures up to the full amount of air pressure being delivered to the spray gun. However, do not exceed 50 PSI at the spray gun or in the paint tank. External Mix Guns: Use lower tank pressures—approximately 12 PSI for most external mix guns.
Tank Setup To use your paint tank and spray gun: 1. Thoroughly mix and strain your paint to remove undissolved particles that could block the flow of material to the gun. Read the manual before operation. Become familiar with this tool, its safety instructions, and its operation before beginning any work. Serious personal injury may result if safety or operational information is not understood or followed. 2.
Spraying The Model H8225 siphon feed spray gun set is designed to spray a wide variety of materials such as lacquers, stains, primers, multi-component paints, clear coats, acrylics, epoxies etc. It is ideal for auto body and woodworking projects. 8.
