Danger | Risk of death. Death may occur if body parts are drawn into rotating vehicle parts. | Do not insert your hand into rotating parts. Wear closed and snug-fitting work clothes. Secure area of rotating vehicle components against unauthorized access. | |
Danger | Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC) | Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines. | |
Danger | Risk of explosion caused by fuel igniting, risk of poisoning caused by inhaling and swallowing fuel as well as risk of injury to eyes and skin caused by contactwith fuel. | No fires, sparks, open flames or smoking. Pour fuels into suitable and appropriately marked containers only. | |
