	Inspecting
4	Clean valves and carry out a visual inspection	 Valves with scorched valve disk, with insufficient height (h) of valve disk or with used or scored valve stem, should be replaced.	*BE05.30-P-1002-01D
5	Measure concentricity at valve stem and valve seat	if necessary replace valve	*BE05.30-P-1009-01D
 Danger!	Risk of explosion and poisoning from melting down and improper handling of sodium-filled valves. Risk of injury from burns and caustic burns to skin sections in the event of contact with sodium.	Do not open sodium-filled valves; if necessary, wear protective gloves and eye protection if valves are damaged.	AS05.30-Z-0001-01A
	Disposing of sodium-filled valves	in the case of exhaust valves with sodium filling	OS05.30-P-0001-01A
