D. MAINTENANCE.
1.
General.
WARNING
Crazing (cracking) of lenses will cause reduced
effectiveness of the light. Do not use cleaning
agents (which will cause crazing) such as
strong detergents, solvents, or petroleum prod-
ucts. If crazing of lenses does occur, reliability
of light for emergency signalling purposes may
be reduced until lenses are replaced.
Ordinary cleaning of the plastic lenses can be
accomplished by using mild soap and a soft rag.
Should fine scratches or a haze appear on a lens, they
can ordinarily be removed with a non-abrasive, high
quality, one-step, automotive paste cleaner/wax and
a soft cloth.
2.
Model GH1 Lamp Replacement.
CAUTION
Use of higher wattage lamps can result in dam-
age to the colored lenses.
a.
See figure 5. Remove and retain the four
screws which secure the lens. Carefully pull the lens
straight away from the grille light assembly.
WARNING
A serious injury may result if lamp is touched
when hot. Always allow lamp to cool before
removing. Halogen lamps are pressurized and
if broken can result in flying glass. Always
wear gloves and eye protection when handling
the lamps.
CAUTION
Service life of lamp will be shortened if glass is
touched. If glass has been handled, clean with
a grease solvent.
b.
Remove the defective lamp by carefully
pulling it out of the socket. Install a new lamp by
aligning the pins on the lamp base with the holes in
the socket, and carefully pushing the lamp into the
socket.
c.
Replace the lens using the previously
removed screws.
3.

power supply before performing any maintenance.
b.
See figure 5. Remove and retain the four
screws which secure the lens. Carefully pull the lens
straight away from the grille light assembly.
c.
Turn the strobe tube assembly counter-
clockwise to unlock it from the finished reflector.
