Danger | Risk of death caused by vehicle slipping or toppling off of the lifting platform. | Align vehicle between vehicle lift columns and position the four support plates at the vehicle lift support points specified by the vehicle manufacturer. | |
Warning | Risk of burn injuries and scalding when working on AdBlue(R) lines and the component parts attached to them. Risk of injury to skin and eyes when handling AdBlue(R). Risk of poisoning caused by swallowing AdBlue(R) | Pour AdBlue® only into suitable containers. Wait until the pressure is released before starting any work on the exhaust aftertreatment system. | |
Warning | Risk of burn injuries, suffocation and poisoning when working on the exhaust system and the components connected to it. Risk of suffocation and risk of poisoning caused by inhalation of gaseous and solid components of the exhaust. Risk of poisoning caused by skin contact with solid components of the exhaust. | Wear protective clothing and safety glasses. Use the extraction system. Move people out of the hazard area. | |
Warning | Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities. | No parts of the body or limbs should be within the operating area of mechanical components when moving components. | |
Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
