wheels, to achieve equal measurements, more than one
eccentric axle change may be required.

Note the number on the floor slope gauge and record that
number along with the bay designate on floor slope sticker
provided. Repeat procedure for other bays and record.

NOTE: After measurements have been taken, remove laser and store in a secure place

3.3 VEHICLE PREPARATION



Remove ice or mud from under the fenders.



Set the tire inflation to the values recommended by the manufacturer.



See that there is no load in the vehicle unusual to normal driving conditions.



Check vehicle springs for sag or broken leafs.



Check function of any automatic leveling systems and specific manufacturers instructions
pertaining to vehicle preparation for headlamp alignment.



Clean lenses, check for bulb burnout, broken mechanical aiming pads, moisture in lens and
proper beam switching.



Stabilize suspension by rocking vehicle sideways.

4. HEADLAMP ALIGNMENT

4.1 ALIGNMENT OF OPTICAL HEAD TO VEHICLE

Place the LCA 2

in front of the first headlamp to be aligned.

Once the LCA 2

is in place, the lens of the optical head should

be approximately 18 inches (+/- 6 inches) from the face of the
headlamp.

Set the floor slope of the eccentric wheel for the bay in which the
vehicle has been parked.

Rotate the sighting unit so that the front of the vehicle can be seen
through the sighting unit. Locate two (2) common points on or
under the hood to align the line in the sighting unit on.

NOTE: Points can be hood stops, radiator supports, points of

fender, etc.

While looking through the sighting unit, align the line of the
sighting unit on the two common points by rotating the base of the
machine.

The LCA 2

is now aligned with the vehicle. Repeat the

alignment process for each lamp.

4.2 CENTERING on the HEADLAMP

Turn headlamps on. Move optical head up, or down to the center of the
headlamp. Position of center of the headlamp is approximate; a

 2”

allowance is acceptable.

TRICK: A method to determining if position is greater than 2” is by observing

the shadows that appear on the aiming screen when moving the
optical head left/right and up/down. Position aimer until no shadows
appear. OR, watch “Visual Assist” meter for highest reading while
moving LCA 2

left/right and up/down in front of the headlamp

to be aligned.
