Cleaning the Lightbar Lens
CRAZING/CLEANING SOLUTIONS—The use of cleaning solutions, such as strong
detergents, solvents, and petroleum products, can cause crazing (cracking) of the
lightbar lens and reflectors. To clean the reflectors, use a soft, damp cloth. To clean
the lens, use a soft cloth and a solution of water and a mild detergent.
CRAZING/CHEMICALS—Crazed, cracked or faded lenses or reflectors reduce
the light output and the effectiveness of the lighting system. A lens or reflectors
showing this type of aging must be replaced. Failure to follow this warning may
result in bodily injury or death.
EQUIPMENT DAMAGE—Do not use a pressure washer to clean the lightbar. Failure
to heed this notice will damage the lightbar.
To clean the lightbar lens:
1.
Rinse the lens with lukewarm water to loosen dirt and debris.
2.
Use a mild detergent, lukewarm water, and a soft cloth to gently clean the lens. To avoid damaging the
finish, do not use heavy pressure or caustic, abrasive, or petroleum-based cleaners.
3.
Rinse and dry the lens with a soft cloth to prevent water spotting.
4.
To remove fine scratches and haze, use a soft cloth and a high quality automotive paste cleaner/wax that
is non-abrasive.
Removing and Reinstalling the Lightbar Lens
The lightbar lens, which is the top half of the INTEGRITY housing, covers the ROC (Reliable Onboard
Circuitry) PCBs and controller PCB.
Tool required:
✔
T27 Torx driver
Removing the Lens
To remove the lens:
1.
Disconnect all power to the lightbar at the battery.
2.
Use a T27 Torx driver to remove the 1/4"-20 Torx-head barrel nuts securing the lens (Figure 5.1).
Carefully remove the lens and cover as a unit. Avoid damaging the lip seal.
3.
Verify that an O-ring is under the head of each barrel nut and not stuck to the lens. Use a wooden or
plastic pick to carefully remove the O-rings from the lens to prevent damaging them.
4.
Inspect the O-rings and the lip seal for deformation, brittleness, cuts, or tears. To maintain
watertightness, replace a questionable O-ring or seal.
5.
Inspect the lens for cracks, crazing (hairline cracks) and other defects.
