WARNING:
WARNING
- Worn exhaust valves with sodium filling must not be disposed of until they have been treated as follows:
- The valves must be sawn into two sections with a metal saw at a point between the center of the shaft and the valve head. They must not come into contact with water when this is done. Then throw the valves into a bucket of water (not more than ten at time). Then step back because a chemical reaction occurs when the sodium filling burns.
- After this treatment the valves can be disposed of in the normal way.
