3.2 Vehicle longitudinal axis positioning with laser
1- Move forward the headlight tester in front
of the centre of the vehicle so that the
headlight tester lens is within 20 and 50 cm
from each headlamp (optimal distance being
35cm).
2- Identify on the vehicle 2 fixed marks,
symetrically spread out with regard to its
central axis (examples : right and left upper
windscreen angles, non distorted engine
bonnet angles, windscreen washer jets if
their support is not distorted).
3- Make the optical head swivel so that the
laser line match with the marks identified on
the vehicle.
4- You can start with the control or
adjustment procedure. During this phase you
will move the headlight tester in front of the
headlamp to be controlled or adjusted while
keeping the angular positioning carried out
with the laser.
WARNING Laser radiation:
- Class 2M laser device
- Do not look directly into the beam nor directly observe using "magnifying" optical instruments.
- The vehicle must be empty of occupants when the laser beam is being adjusted.
- Laser adjustment must be used momentarily.
