Operation

Charging Air Tank

1. Start engine and engage clutch. Compressor is now
engaged.

2. If compressor is not needed for a job, move com­pressor bypass switch (9) to horizontal ON position.
Compressor is now exhausting air into atmosphere.

3. Move compressor bypass switch (9) to vertical OFF
position to charge air pressure tank. Air tank will
continue to charge to 80 psi (5.5 bar, 55 MPa) then
cycle between 60-80 psi (4.1-5.5 bar, 41-55 MPa).

Setting Bead Hopper Pressure

The pressure regulator valve (5) controls pressure sent
from the air tank to the bead tank. The regulator is set
to 0 pressure from the factory.

1. Before charging bead tank, confirm that bead tank
lid is fully secured and beads have been loaded into
tank.

2. To increase pressure, pull knob on pressure regula­tor valve (5) out and turn counter-clockwise. Watch
bead tank gauge (4) pressure and continue turning
valve until desired pressure is met.

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 Table, page 24.

ti21326a

Operation

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.

332230F 23

Operation

Determining Bead Application Pressure

The table below lists bead delivery rates for 4 inch
(10 cm) lines with standard size highway beads.

• Wider lines use multiples of 4 in. to determine bead
delivery.

• Larger beads reduce flow rates, so a larger nozzle
and higher pressure may be required.

• Always verify flow rates with a stopwatch and a
scale for weight.

To determine application pressure, follow steps 1 - 4
below:

1. Determine speed the machine will travel when
applying line.

2. Identify what the required bead delivery rate is in job
specifications.

3. Under bead gun nozzle size, find nearest value
compared to Step 2.

4. Match pressure needed to Step 3. Set air regulator
to this pressure.

† EXAMPLE:

a. At 4 mph and 6 lb/gal with 0.234 nozzle set tank

pressure to 15 psi.

b. At 4 mph and 6 lb/gal with 0.281 nozzle set tank

pressure to psi.

Operation

1. Move compressor bypass switch (9) to horizontal
position to disengage compressor or turn engine off.

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.
