Maintenance

5.1 Cleaning

Routine cleaning is recommended for maximum performance. The following cleaning methods are recommended:

•

Clean with sponge, cloth, or soft brush using water and detergent

•

Automatic truck/car wash or standard high-pressure hand spray under following conditions:

-

Maximum pressure: 1200 PSI/80 bar

-

Maximum water/wash solution temperature: 140° F (60° C)

-

Minimum of 12 inches (30 cm) between cleaning jet(s) and marking

-

Cleaning wand or jets at angle of no more than 45 degrees from perpendicular to the marking surface

-

Use spray tip #1505 (15 degree spray angle, 05 capacity size)

•

When using metal brighteners, follow manufacturer's recommendations for dilution. Thoroughly rinse brightener

from markings after soaking vehicle

Observation

a. Observation Angle - the angle between the illumination axis and the observation axis.

Entrance

b. Entrance Angle - the angle between the illumination axis and the retroreflector axis. The retroreflector axis is an axis perpendicular to the

retroreflective surface.
