

Check all other mounting screws, bolts and nuts
for tightness.



Clean the mast area where the brake rides with a
mild detergent to assure of secure holding.



Clean the front lens, sighting unit and viewing
window with a mild detergent being careful to
use a non-abrasive soft cloth.

6. FREQUENTLY ASKED QUESTIONS

Question: Level in optical head is not centered during alignment procedure?

Answer:

Level vial is used ONLY when checking the calibration of the floor slope laser.

Question: The high intensity (hot spot) area of the headlamp is difficult to determine?

Answer:

All lamps are legislated to be created equal, but this has proven not to be the case. A trick in
determining where the high intensity (hot spot) area of a lamp is to move your hand around in the
front of the optical head lens while viewing the aim screen, the high intensity area will become very
apparent.

Question: Do I have to check for floor slope every time I perform a headlamp

alignment?

Answer:

Floor slope need only be performed one time in each bay that the LCA 2

is to be used. When

determining the floor slope, record the reading of the rear eccentric wheel on the sticker provided,
Each time you are in that bay, refer to the sticker and adjust the rear eccentric to that measurement.

Question: Why is there a mast extender included with the LCA 2

Answer:

The mast extender is provided to raise the optical head to a maximum height of 54”, which is the
maximum legal limit of headlamp placement. It is not recommended that the mast extender be
assembled at time of initial set-up, as the majority of vehicles are below the 45” height of the LCA
2

without the mast extender.

Question: Must I re-calibrate the Sighting Unit when I rotate it around for taller, or shorter technicians?

Answer:

YES. It is good operating procedure to always check the Sight Unit calibration prior to all headlamp
alignments. When different height technicians are using the system, re-calibration is sometimes
required when rotating the sight unit from a high to low position.

Question: I cannot attain equal readings at the front wheel and the rear wheel areas when determining the

floor slope.

Answer:

The only time that this can occur is when the shop bay has an abnormally excessive angle of slope.
The most frequent problem with determining floor slope is patience in adjusting until the
measurements are equal. A TRICK to assist in making this measurement is to first measure the height
of the laser at the optical head. Then turn the eccentric wheel until the laser reading matches the
measurement of the optical head at the rear wheel area. Check readings at front and rear wheel areas
and make, if any, minor adjustments to equal measurements. RECORD READING OF ECCENTRIC
WHEEL FOR FUTURE REFERENCE.

Question: What do I use as reference when squaring the LCA 2

to the vehicle and do I need to

square again when moving from one lamp to another?

Answer:

It is always recommended to check the alignment of the sight unit to the vehicle for every lamp to be
aligned. Some reference points that are prominent on most vehicles are the grill, hood line, radiator
support, hood bumpers and common assembly point bolts. Always pick two points that are of equal
proportion.
