Air and Bead System
PROBLEM CAUSE SOLUTION
Belts squealing during engine startup Compressor belt needs tightening or
replacing
See Air Compressor Belt Replace-
ment, page 9.
Paint guns not spraying when empty
bead tank is empty
All of air supplied by air compressor is
rushing out of bead gun nozzles. In turn,
system air pressure cannot build
enough to trigger guns. This is normal.
Fill bead tank with beads or turn off air
supply to bead tank.
No system pressure Compressor bypassing air continuously
1. Make sure silver switch on top of
unloader valve (148) is turned hori-
zontally.
2. Move silver switch on top of unloader
valve (148) up and down. This might
loosen a sticky valve.
3. Replace unloader valve (148).
Beads not dispensing properly Excessive water or moisture in bead
tank
1. Only pressurize reflective materials
when dispensing. Small air leaks at
gun nozzle or air fittings cause con-
tinuous moisture to be pumped into
tank.
2. For areas of extreme humidity a Ben-
dix air dryer or equivalent may be
installed in air line bead tank. Typi-
cally when beads are used continu-
ously, they do not spend enough
time in tank to collect enough mois-
ture to be a problem. Usually it is
continuous stencil painting for long
periods of time with little bead con-
sumption and high humidity that can
cause problems.
Low system pressure Excessive air leaks
1. Fix all air leaks before they become
a problem. Air leaks can eventually
starve system air supply.
2. Most air leaks occur at bead tank
outlet fitting. If fitting leaks air, com-
pletely remove it and use thread tape
and liquid thread sealant before rein-
stalling it.
No beads dispensing Beads have solidified
1. Never store RoadLazer with reflec-
tive materials in tank for long periods
of time.
2. Remove aluminum fitting from bot-
tom of tank. Flush out solidified
beads.
3. Use air hose or water hose to break
up and remove solidified beads from
tank.
