4. See bead tank gauge (4) to read air tank pressure.
Pressure from air tank is used to open bead valves
at bead gun.

3. See bead flow chart to find proper settings for your
application.
4. Various orifices can be used in gun to obtain different flow rates in conjunction with bead tank pressure. See Determining Bead Application
Pressure page 30.

Operation
Bead Timing With Gun
1. Use air flow restrictor valves to help time the opening 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 opening/closing time. Turning the valve counter-clockwise will speed up gun opening/closing time.
NOTICE
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.

Determining Bead Application Pressure
Determining Bead Application Pressure
The table below lists bead delivery rates for 4 inch (10
cm) lines with standard size highway beads.
2. Identify what the required bead delivery rate is in job
specifications.
•
Wider lines use multiples of 4 in. to determine bead
delivery.
3. Under bead gun nozzle size, find nearest value
compared to Step 2.
•
Larger beads reduce flow rates, so a larger nozzle
and higher pressure may be required.
4. Match pressure needed to Step 3. Set air regulator
to this pressure.
•
Always verify flow rates with a stopwatch and a
scale for weight.
† EXAMPLE:
To determine application pressure, follow steps 1 - 4
below:
1. Determine speed the machine will travel when
applying line.
Step 1
b. At 4 mph and 6 lb/gal with 0.281 nozzle set tank
pressure to 10 psi.
c.

2. Release pressure on bead tank to 0 psi (0 bar, 0
MPa). Turn pressure relief valve (8) to vertical position and watch bead tank pressure gauge (3) until
pressure reads 0 psi (0 bar, 0 MPa). Do not use
safety valve (3) to release pressure from bead tank.

4. Place funnel (1) into opening. Pour beads into hopper. Beads should not be filled to a height higher
than shown in figure below. Bead level can be
viewed through tank wall if light is present.

5. Secure lid over opening and tighten wing nut until lid
is level with hopper.
3. Loosen wing nut (2) until it reaches end of threads.
If any remaining pressure is in bead tank, it will be
released through seal while wing nut secures lid to
hopper. Confirm pressure is at 0 psi (0 bar, 0 MPa)
and open lid.
