Paint guns and bead guns
If paint guns and bead guns or not working,
check paint guns first.
Bead tank air valve
Turn bead tank valve ON
Nozzles plugged
1. Turn off air pressure.
2. Remove nozzles and clean out any plugging
3. If paper or other debris is constantly plug-
ging nozzles use a filter when loading bead
tank (standard window screen works fine).
