  WARNING
t  Worn exhaust valves with sodium filling must not be disposed of in the normal way.
t  The valves must be sawn in two with a metal saw between the centre of the stem and valve head. When doing so, valves must not come into contact with water. After preparing the valves, throw a maximum of ten into a bucket of water. Then you must remove one piece, as a chemical reaction will be triggered where the sodium filling is burned-off.
t  After performing these steps the valves can be disposed of in the normal way.
