Without passengers in the car, cover one headlamp to obscure its beam and place
lighting switch in the high or country driving position.
To Adjust the Beam Vertically:
Turn both adjusting screws (A and B), Figure 60, with a narrow screwdriver the
same number of turns clockwise to raise the beam, counter-clockwise to lower the
beam.
To Adjust the Beam Horizontally:
To move the beam toward right: Turn the right adjusting screw (B), Figure
60, counter-clockwise until beam has moved approximately half the desired distance
to the right. Turn left adjusting screw (A) clockwise until beam has reached the
proper position on the horizontal axis. It may then be necessary to readjust the beam
on the vertical axis by turning both adjusting screws the same amount clockwise to
raise the beam, counter-clockwise to lower the beam.
To move the beam toward left: Turn the right adjusting screw (B) clockwise and
the left adjusting screw (A) counter-clockwise, proceeding as outlined above.
LAMP LENS AND BULB REPLACEMENTS
To replace headlamp lens and bulb, loosen screw (C), Figure 60, at bottom
of lamp body. Push bottom of lens backward and downward until the top of the lens
is clear of the top of the lamp body and lift out. Remove bulb by turning counter-
clockwise. Replace bulb, turning same in clockwise rotation to lock in reflector.
Replace lens.
To replace headlamp parking bulb, remove lens as outlined above. Press
parking bulb inward and turn to release it from socket. Replace with new bulb.
Do not touch the reflector, as any marks will reduce the illumination. Should
it be necessary to clean the reflector, use ordinary lampblack on a soft cloth and wipe
gently in a circular motion.
If the reflectors require frequent cleaning, it is an indication that the gaskets are
not giving a proper seal and should be replaced.
