These spray techniques discuss how to use and adjust
the features of the LineLazer. You must also consider op-
erator technique, job site conditions and weather.
1. Use water rather than paint to practice spraying tech-
nique and positioning the gun. Slight readjustment
may be required when switching from water to paint.
2. Be sure the RAC IV Tip Guard is always parallel to
the ground and the "wings" of the spray tip guard face
the front and back of the unit, as shown in Fig. 4.
WARNING
To reduce the risk of a fluid injection injury, always
disengage the remote trigger cable to the gun and
engage the gun trigger safety latch before moving
or adjusting the spray tip guard, gun, or gun arm.
3. Use the lowest pressure necessary for good atom-
ization. High pressure may cause excessive paint
buildup and overspray.
4. Start moving the LineLazer before triggering the gun
to prevent a build up of paint at the beginning of the
line. Release the trigger a second before stopping
the LineLazer. Move at an even rate of speed.
5. Always check your gun adjustments on cardboard or
paper before starting each job. When painting curbs,
paint first in an area that is less frequently seen.
6. Keep in mind that many factors affect the straight-
ness of a line, including uneven surfaces, potholes,
rocks and other debris and a clogged or worn spray
tip. See manual 308235 for how to clear or change
a spray tip.

Spray Techniques
7. To minimize the effect of bumps on the spray pattern,
keep the spray tip guard centered with the front
wheel axis.
8. The spray tip size and the rate at which you move the
unit affect the coating thickness. Generally, the fast-
er you move the unit, the larger the spray tip orifice
should be. The fan width of the spray tip indicates ap-
proximately how wide the line will be.
9. Position the gun to suit your requirements. See the
section below and pages 13 to 14.
10. Traffic paints may be formulated for air spray, airless
spray or have no formulation description.Generally,
air spray formulas are pre–thinned, and will work well
in the LineLazer, but there may be more overspray.
Non-air spray formulas tend to deliver more lineal
feet of line per gallon with less overspray, since they
are less easily absorbed into the pavement.
11. If you use fast–drying traffic paint on a hot day, float
compatible solvent on top of the paint to prevent skin
from forming on it.
Line Width Adjustment
Several factors affect line width: vertical distance of the
spray tip to the spraying surface, spray tip fan pattern,
paint pressure, and a worn or clogged spray tip.
The typical conditions for a 4 in. wide line are: 317 size
LineLazer Tip (supplied), the gun positioned one inch
from the lowest vertical position, and just enough pres-
sure to atomize the paint. Depending on the fan pattern
of the spray tip, the gun can paint 2 to 12 in. wide lines.
To decrease line width, lower the gun (if possible) or use
a tip with a narrower fan pattern.
To increase line width, raise the gun, or use a tip with a
wider fan pattern.
