 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.	AS00.00-Z-0004-01A
 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.	AS00.00-Z-0035-01A
 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. Wear protective clothing when handling fuel.	AS47.00-Z-0001-01A
