hand lamp until the string is positioned over the

crossarm centerline. Turn the screw clockwise

in making the final adjustment to take up play in

the headlamp mechanism.

Repeat the above procedure on the right-hand

lamp to complete the horizontal adjustment of the

headlamps.

VERTICAL ADJUSTMENT

8. a. Numeral "2" (fig. 5) should appear in the "down"

window of each aimer. If not, loosen knob at

underside of aimer arm and slide back and forth

until the numeral does appear.

NOTE:
This setting will give a 2" drop of the

headlamp high beam spot centerline on a screen

placed 25 feet forward of the vehicle. Check

state laws for proper vertical setting.

b.
Turn headlamp vertical aim screw (fig. 5) on left-

hand unit counter-clockwise until the bubble is at

the inner end of the glass tube. Then turn screw

clockwise until bubble is centered in tube.

c. Repeat this procedure on right-hand headlamp

unit to complete vertical adjustment of lamps.

9. Recheck the string at the ends of each crossarm for

correct setting and the bubble on each aimer for

centered position.

10.
Remove the aimers by pulling on the suction cup tabs

through the openings in the aimers (fig. 6).

11.
With headlamps properly aimed, replace headlamp

bezels.

HOW TO SELECT A LEVEL AIMING AREA

1.
Select area you believe to be level.

2.
Remove headlamp bezels and install Aimers on each

headlamp (fig. 3) making sure aiming lugs engage

smoooth inner ring of the Aimer.
"
To install Aimer,

press firmly on the knob extending out from the cen-

ter of the Aimer base. This forces the suction cup

into place on the Sealed Beam unit.:

3.
Loosen the slider knob beneath the aimer arm and

set the numeral "2" in the DOWN view window (fig.

7).
Back vertical lamp adjustment out on each lamp

until bubble is outside of black line of vial, then cen-

ter bubble in between black line of vial by turning

clockwise.

4.
After botli bubbles are centered, turn the car around

end for end, making sure the tires are in the spots

made on the floor before the car was moved.

.5.
If the bubbles are still within the two outside black

marks on the vials, the floor is level enough to use

the Aimer as it comes from the factory.

NOTE:
A quick level check can be made by

using the T-3 Safety-Aimer as a level. Use

with a true eight to ten foot two by four as an

extension. Make sure pads on base of Aimer

are used. Place the board where you expect the

wheels to be and take readings as outlined above.

6. If either bubble moves outside the black lines of the

vial there is too much slant to the floor. Try driving

the car in at different angles onto the aiming area.

If bubbles can
not
be centered follow procedure under

"How to Compensate for Unlevel Floor."

NOTE:
When level portion of floor is obtained,

mark tire spots on floor so spots can be used

next time without calibrating Aimer.

TO COMPENSATE FOR UNLEVEL FLOORS

If your floor is not level within the limits specified, the

T-3 Aimer can be calibrated to compensate for the error

in the floor. Follow this procedure with both aimers.

1.
Drive the car onto the area for which you wish to

compensate the aimers, and install the aimers in

place on the headlamps.

2.
Loosen knob beneath the aimer arm and move the

slider until the bubble is centered.

3.
Record the numeral in the view window. (This nu-

meral is to be used only for recalibration.)

4.
Move the slider to a position halfway between this

recorded numeral and the numeral "2" in the
DOWN

window. (This numeral is used only in recalibration

and not for headlamp aiming.)

5.
Recalibrate aimers by turning screw shown in Figure

8 until the bubble is centered.

6. The T-3 Aimers are now calibrated for the selected

area. All future aiming must be done in the same

area and with the car pointed in the same direction.

Mark the tire spots on the floor so that other vehi-

cles can be located in the same position.

HEADLAMP PANEL TRAVEL ADJUSTMENT

Corvette (Fig. 9)

The headlamp panel travel is limited by two adjusting

screws which are located on the arms of the shaft

mounted stop.
Fig.
9—Headlamp Panel Travel Adjusting Screw

1.
Raise hood and as a safety precaution install a bolt

through the hole in the hood support - secure bolt

with a nut.

2.
Adjusting screw (A) limits headlamp panel travel in

open position - adjust this screw so that mounting

face of panel is within 2 degrees of vertical in the

fully open position.

NOTE: Each headlamp operates independently

of the other, therefore individual adjustment is

required for each panel.

3.
Adjusting screw (B) limits headlamp panel travel in

closed position - adjust this screw so that panel is

flush to upper body panel in the fully closed position.

4.
Lock both screws by tightening lock nut against stop.

5.
Remove safety bolt as installed in Step 1 and close

the hood.
