Note<\/strong><\/div>\n
The exhaust valves are filled with sodium!<\/div>\n
Observe safety regulations when scrapping. Because of the danger of explosion sodium filled valves must not be melted or converted into tools (punches, etc.), without first removing the sodium filling.<\/div>\n
Be careful when removing sodium from valves, since sodium reacts violently and explosion-like when com\u00adbined with water and watery solutions, to avoid any risk of fire caused by the resulting hydrogen gas.<\/div>\n
Sodium from cut and broken valves can be neutralized in the open air in a vessel container in a mixture of 2 liters of spirits of alcohol and 1 liter of water.<\/div>\n
Sodium filled valves can be collected and sent for neutralization to the Warranty Checking Department at Stuttgart-Unterturkheim.<\/div>\n<\/div>\n<\/td>\n
