Checking and setting headlamps (National regulations must be observed)
a) Headlamps with symmetrical dipped beams
Dipped beam
Main beam
1. Align the beamsetter as described in Section 4.0.
2. Set the scale wheel as shown on the adjustment table.
3. Switch on dipped beam:
The cut-off line must run as near as possible to the horizontal along the
whole of the dividing line and the whole width of the screen.
4. Correct the headlamp setting as necessary by means of the adjustment
screws.
5. Turn on the main beam.
The middle of the main beam must lie on the centre marking
6. correct if necessary with the adjustment screws.
7. If the same adjustment screws are used for both main and dipped
beams, recheck the dipped beam.
b) Headlamps with asymetrical dipped beams
Dipped beam
Dipped beam bi-xenon
1. Align the beamsetter as described in Section 4.0.
2. Set the scale wheel as shown on the adjustment table.
3. Switch on dipped beam:
In the case of headlamps with asymmetrical dipped beams, the cut-off
line must run along the dividing line on the test surface. The sharp angle
dividing the left-hand and the right-hand sloping parts of the cut-off
line must run vertically through the centre marking (upper cross). The
bright centre of the light beam must lie closer to the near side than the
vertical line running through the centre marking.
In order to determine the position of the sharp angle more easily, cover
and then uncover the offside half of the headlamp a few times.
4. Then recheck the dipped beam.
Main beam: Following the prescribed setting of the cut-off line of the dipped beam, the middle of the light
beam must lie on the centre marking (upper cross).
