ALIGNMENT WITH LASER POINTER
Switch on the laser through the button on the lateral side of the optical box. From the centre of the lens, a laser ray will allow to
find the centre of the beam. Once the alignment process is completed switch off the laser to avoid a fast batteries discharge.
(FIG.24)
CAUTION!
During this operation, do not look directly the laser ray and make sure that this is not directed at persons nearby the working
area.
ALIGNMENT WITH THE VEHICLE
The operator and designer of the working area must be aware of the risks deriving from the laser. The island must not be
located in a transit zone and must be well marked and outlined by a yellow line, and possible enclosed with special barriers.
Make sure there are no people in the test zone, turn the visor downward and switch it on.
Locate two details on the front of the vehicle, such as the headlights themselves, turn the optical chamber
until the two reference points meet the line projected by the visor and block the column. (FIG.25)
CAUTION!
Switch off the laser immediately before proceeding with the other operations of control and possible adjustment of the
headlight.
The laser line is in class 3A with a wave length of 650 nm (nanometers) and a power of 3 mW (milliwatts) which means that
even only direct observation of the beam with the use of amplifying optical devices such as binoculars can be hazardous.
Accidental exposure is not considered hazardous as, since it is in the visible range, the eyelid reflex does not permit an
exposure of more than 0.25 sec.
HEADLIGHT TEST
ADJUSTMENT
Inside the motor compartment, read at the top of the headlight the tilt indicated by the manufacturer, e.g. 1.2%, and turn the
knob on the rear part of the optical box as indicated.
If there is no indication by the manufacturer, comply with the laws in force in your country. (FIG.26)
LOW BEAM TEST
Check the position of the low beam headlight projection on the control panel inside the optical box.
If the light-dark division line on the left is aligned to the horizontal line printed on the panel, this means that inclination is
correct. If it is not correct, adjust the beam through the screw on the motor compartment.
If the light-dark division area is aligned to the inclined line printed on the panel, this means that horizontal orientation is correct.
If it is not correct, adjust the beam through the screw on the motor compartment. Only when the beam is correctly aligned,
press on the switch with the low beam symbol and read and check if light intensity on the lux meter complies with the limits of
the laws in force. (FIG.27)
HIGH BEAM TEST
Proceed and centre the high beam projector if different from the low beam.
Check the position of the high beam headlight projection on the control panel.
Maximum light intensity zone has to be centered or inside the square in the middle of the panel.
If the two optical groups have separated adjustments, adjust the position through the screws on the motor compartment. If
not, check the position of the lamp or adjust the position through the screws on the motor compartment.
Only when the beam is correctly aligned, press on the switch with the high beam symbol and read and check if light intensity
on the lux meter complies with the limits of the laws in force. (FIG.28)
IMPORTANT: If you performed an adjustment, verify once again the low beam position to ensure that its position is ok.
FOG LIGHT TEST
If present, displace and centre the headlight tester on the the fog beam projector. On the headlight tester turn the knob on the
rear part of the optical box according to the manufacturer indications.
If there is no indication by the manufacturer, comply with the laws in force in your country. (FIG.29)
Check the position of the fog beam headlight projection on the control panel inside the optical box.
The division line between dark and light has to be aligned to the horizontal line printed on the panel and the projection has to
be aligned in connection with the centre, if not aligned, proceed with the adjustment through the adjusting screws. (FIG.30)
