Headlights: Check adjustment
Headlights: Check adjustment
In principle, the following conditions for adjustment and verification are valid for all countries. But legal guidelines and prescriptions of each country should be followed.
→ Chapter „Adjusting the headlight“
Special tools and workshop equipment required
   
t  Headlight aligner -SAT 6100-
Conditions for checking and resetting
l  The vehicle and the lamp regulating equipment should be on a flat surface
l  Fuel tank full
l  Correct tyre pressure
l  The headlamp glass should not be damaged or dirty
l  Correct reflectors and lamps
l  Loading: With one person or 75 kg on the driver seat with unloaded vehicle (dead weight)
l  Switch for adjusting the headlight height: in position „0“
l  The vehicle must have run a little, or the front and rear shock absorbers should be pushed up and down several times, so the springs are correctly seated.
l  The handbrake must be released to avoid tension in the suspension
l  The vehicle and the headlight adjuster -SAT 6100- must be aligned
l  The distance between the lamp alignment unit and the lamp should be 20 to 30 cm →  Instruction manual for the lamp alignment unit
The inclination heights in „%“ are engraved on the left-hand side of the headlamp. Headlights must be adjusted according to this information. The percentage is based on a projection interval of 10 m. Example: Converting a dip setting of 1.0 % = 10 cm.
Check the adjustment of headlamps (with a new display without an adjustment line of 15°)
Perform the following check of the main headlamps:
  L00-10225
–  Check that with the dipped beam on, the bright/dim horizontal limit touches the dividing line -1- of the verification surface.
–  Check if the break-away point -2- between the horizontal section of the light-dark border on the left and the rising section on the right should coincides with the vertical line running through the central point -3-. The clear centre of the light beam should be, in this case, to the right of the vertical -4-.
Check the adjustment of headlamps (with display with adjustment line of 15°)
Perform the following check of the main headlamps:
  E94-0026
–  Check that with the dipped beam on, the bright/dim horizontal limit touches the dividing line -1- of the verification surface.
–  Check if the right raising part touches the Bright/dim limit of the adjusting line of 15°, which starts to go up after the point of inflection -2-. The clear centre of the light beam should be, in this case, to the right of the vertical -4-.
For both methods:
  Note
t  To better locate the point of inflection -2-, follow the bright/dim limit on the extreme limits -5- from left to right, and find the intersection point with the prolongation of the line of 15° of the bright limit/ dim limit, following from top to bottom.
t  After the regulatory dipped beam adjustment, half of the light beam of the road lamp should be on the central mark -3-.
t  If the alignment unit of the headlamps is well regulated, it may be verified that in the final lamp position the acceptable limit value of light intensity is not overshot (normally < 1 lx). If this limit value is overshot, the alignment should be repeated to avoid dazzling other drivers. → Instructions for the use of the lamp alignment unit and valid regulations in each country
t  It is recommended to align the headlamps with the verification screen at an adjust line of 15 °.
t  Moreover, the final position of the headlamps may be verified with a vertical wall situated 10 meters from the vehicle with the lamp alignment unit. → Operating instructions for headlight adjustment unit
Control of main beams
Switch on the main beams after adjusting the passing beam. A very illuminated area can be seen in the centre of the plate. If this is not the case, adjust the headlights to the left or right.
  Note
After checking the adjustment and when an adaptation should be necessary → Chapter
