Ford Low Cab Forward (Ford year). Manual — part 9

Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Lamp (DRL) system

does not activate your tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.

PANEL DIMMER CONTROL

The panel dimmer control is located
to the left of the steering wheel on
the bottom edge of the instrument
panel. Use the dimmer to adjust the
brightness of the instrument panel
and all applicable switches in the
vehicle during headlamp and
parklamp operation.

AIMING THE HEADLAMPS

Place the vehicle with the following conditions:

1. The area around the headlamp is not deformed.

2. The unloaded vehicle is parked on a flat level surface.

3. Tire inflation pressure is at the specified value.

4. The vehicle is in a state ready for driving (with a full tank of fuel, oil
level, and coolant).

5. The vehicle has been bounced several times.

Checking headlamp aim

1. Prepare a thick white paper.

2. Stand the paper perpendicular to the ground at a position 9.84 ft.
(3 m) (#1 in the illustration) away from the headlamps.

3. Ensure that the centerline of the vehicle and the paper face forms a
90° angle (#2 in the illustration).

4. Draw a horizontal line (#3 in the illustration) on the paper at the same
height from ground as the headlamp bulb center, which is marked on the
headlamp lens by a 2 mm x 2 mm square.

5. Draw a horizontal line (#4 in the illustration) parallel to the headlamp
bulb center line (#3 in the illustration) but 0.82 inches (20.9 mm) (#5 in
the illustration) below it.

6. Take appropriate measures to prevent any influence of other lights.

7. Start the engine.

8. Turn the low beam of the headlamps on.

9. On the paper, observe the portion of the light pattern with a distinct
area of higher intensity light. Check that the top edge of this high
intensity area is at the horizontal reference line (#4 in illustration) and
below the cross-hatched area shown in the illustration. If it isn’t, adjust
the headlamps in the vertical direction.

Use this illustration to check the headlamp aim pattern as it should
appear on the paper.

3. Horizontal line at headlamp bulb center.

4. Horizontal lines for headlamps, 0.82 inch (20.9 mm) below bulb
center.

5. 0.82 inch (20.9 mm).

6. High intensity area of light pattern.

Adjusting the headlamp aim

IMPORTANT: Both the inboard and outboard vertical aim screws must
be turned the same amount in the same direction. Do NOT turn the
screws different amounts or in different directions.

Note: Do not finish the aiming procedure by turning the screws in the
counterclockwise screwdriver direction. If you are adjusting in the
counterclockwise screwdriver direction, overshoot the adjustment by one
full turn and then turn the screwdriver clockwise one full turn, so you
finish the adjustment in the clockwise direction and still line up with the
vertical aiming line. This applies to both screws.
