Bead Timing With Gun
1. Use air flow restrictor valves to help time the open-
ing and closing of the bead guns to best match the
start and stop of paint lines.
2. Valve (X) is exhausting air and will control the timing
end of the bead application. Valve (Y) is sending air
to the gun and will control the timing of the start of
the bead application.

3. Turning the valve clockwise will delay gun open-
ing/closing time. Turning the valve counter-clock-
wise will speed up gun opening/closing time.
Never store glass beads in tank between jobs. Begin the
day with moisture-free beads. Moisture will cause glass
beads to resist flow or solidify over time.
If moisture or condensation is present on tank interior,
leave lid open until dry. When operating without the bead
system, always leave the moisture drain valve open.
