1. Distance between headlight centres
2. 5 m (tractor distance from the wall)
3. Height of headlights above ground minus 50 mm
Headlight adjustment can be carried out quickly and accurately by using an
optical headlight adjusting unit. If no optical instrument is available, the
adjustment can be done as follows:
1. Turn on the dipped lights.
2. Measure that the cut-off edge of the light pattern comes at height of
headlights above ground minus 50 mm when the tractor is 5 m from the wall.
3. Turn the full beam lights on.
4. Measure that the distance between headlight centres matches the distance
measured on the wall.
5. Adjust the lights using the headlight adjusting screws.
If the tractor has raised full/dipped beam headlights (on the top part of the cab),
the lights have to be adjusted so that the light pattern shines on the mark where
the ground is even and the distance is 30 m.
