Headlight range adjustment

Additionally, a pneumatic headlight range adjustment can be installed. Adjustment is carried out by a rotary switch next to the light switch, depending on the degree of vehicle loading and the distribution of the load evenly or predominantly on the rear axle. Since the adjustment parameters are not the same for different models, please refer to the instruction manual. If there is no instruction, contact a specialized service station for clarification. The corrector uses a vacuum drive. In order to keep the pressure constant at any speed, the vacuum system is equipped with an expansion tank. There is a check valve to prevent pressure drop in the system. The pressure is controlled by turning a switch on the instrument panel, which activates the headlamp controls. The maximum travel of the regulators is 3 mm.
