2 – ASSEMBLY OF THE OPTICAL BOX SLIDING SYSTEM ON THE COLUMN
Insert the sliding system of the optical box on the bottom part of the column already fixed on the base. In order to facilitate the
insert of the sliding system, keep pressed the locking position lever. Be careful to the correct positioning of the brake pad of
the sliding system, respecting the correct direction as indicated in the picture aside. (FIG.11 & FIG.12)
3 – ASSEMBLY OF THE TOP HALF PART OF THE COLUMN
Mount the top part of the column inserting the brackets already assembled into the other part of the column and fix the
brackets with the screws supplied. Pay attention to mount the two pieces of the column aligning them in the same direction of
the graduated scale, as indicated in the picture. (FIG.13)
4 – ASSEMBLY OF THE OPTICAL BOX ON THE COLUMN
Extract from the package the optical box, loosen the fixing screws (1) of the sliding system cover, insert the optical box (2) from
the top into the position of the column sliding system, until it is completely into place. Fix the optical box to the sliding sys-
tem through the screws supplied, from the bottom part of the optical box (3). Tighten the fixing screws of the sliding carter (1).
(FIG.14)
5 – ASSEMBLY OF THE VISOR ON THE COLUMN
The visor has been calibrated during testing procedures, therefore it is not necessary to recalibrate it when it has to be
assembled. (FIG.15, FIG.16 & FIG.17)
• Insert the fixing screw, the spring and the washers into the column as indicated in the picture aside.
• Position on the opposite side the adjusting plate pre-calibrated.
• Screw the visor up to tighten completely.
6 – LEVELING OF THE MACHINE
In order to carry out a correct measurement and adjustment, the headlight tester has to be leveled. The unit is always leveled
during production process and testing procedure before shipment. If the floor of the working area is not leveled, please follow
the instructions below:
Inside the optical box there's a bubble level and the base has a rear wheel and the farthest wheel from the column, both
adjustable. (FIG.18 & FIG.19)
• Locate the headlight tester in the working area
• Lower the optical box until the lowest point possible
• Loosen slightly the fixing screw of the wheel (1)
• Through the upper screw, adjust the inclination (2) until the bubble is inside the reference circle.
• Tighten the fixing screw of the wheel (3)
• Check once again the bubble inside the optical box.
PREPARATION
PREPARATION OF THE VEHICLE
Make sure the headlights are clean and dry. If the vehicle is equipped with a headlight aligner, set in on "0". Eliminate anything
that could affect the correct position of the vehicle: mud, snow, ice, etc. Straighten the car wheels. Make sure the vehicle does
not have any distortions of the frame. Make sure the tires are inflated at the correct pressure. Start the engine and perform the
test. In case of vehicles with pneumatic suspension, start the engine five minutes before starting the test and proceed with the
engine running.
CAUTION!
When operating in an enclosed space with the engine on it is essential to evacuate the toxic gasses produced by combustion.
We recommend using a specific fan for exhaust fumes.
WORKING SURFACE
During the headlight test the floor surface must be level. If this is not possible, the headlight tester should be positioned on a
surface with a uniform slope, in any case not exceeding 0.5%.
Do not test headlights on floors that are not perfectly regular and level, as the measurement might not be accurate. (FIG.20)
ALIGNMENT WITH THE VEHICLE
POSITIONING
Place the headlight tester in front of the right headlight of the vehicle at a distance of about 20 cm, measure the height from the
floor at the center of the headlight and adjust the optical chamber at the corresponding height using the graduated scale on
the column. (FIG.21 & FIG.22)
As index of the scale, please use the upper part of the slider runner. (FIG.23)
