Assembly:
1. Slide the nut onto the static mixer.
2. Choose an air cap and connect the air baffle to the static mixer (lining up the notches).
3. Attach the static mixer to the cartridge (line up the notch to the front of the cartridge), Attach the air hose to the end of the static mixer.
TECH TIP: Attach quick couplers to the Quick Spray System to easily add or remove attachments.
Application:
1. Use the set screw to control the air pressure.
TECH TIP: Run some product into the static mixer before turning on the air. This prevents an air bubble from backing into the cartridge.
2. Adjust the air pressure to achieve your desired texture. Too little air pressure will produce a normal-looking bead. Too much air pressure will cause the product to spit.
TECH TIP: You can also vary the texture by adjusting your distance from the panel.
Cleaning:
Clean the Quick Spray System by cleaning only the end of the air cap. In many cases, you can just allow the product to dry and then snap or flick it off the air cap.
