8. | Working with the Device
• The vehicle is unloaded (for single or multi-track vehicles with just one headlight). Put a weight of 75 kg on the driver
seat.
Observe the manufacturer's specifications in general.
• Do not load lorries or multi-track vehicles.
• Load single-track vehicles or single-axle tractors and work machines (with driver cab or trailer) with one person or
75 kg on the driver's seat.
• Observe manufacturer specifications for vehicles with hydraulics or air suspension.
• If automatic correction of the headlights or continuously variable or multistage adjustment is possible, then observe
manufacturer specifications. Depending on the manufacturer, various function tests must be carried out here.
• A diagnostic device, e.g. from Hella Gutmann, is required to apply settings for various vehicles with automatic head-
light leveling. The vehicle ECU must be in basic mode during the setting process. If the light-dark border is set cor-
rectly, then this value is stored as the new normal position.
• For headlights with multi-stage adjustment systems where position settings are not marked especially, proceed as
follows:
– If the light beam lifts with increased load, then apply the setting for the adjustment setting where the light beam
sits highest.
– If the light beam lowers with increased load, then apply the setting for the adjustment setting where the light
beam sits lowest.
8.2.4. Setting Dimensions and Tolerances
