WARNING

Dry--cleaning solvent (P--D--680) used to clean parts, is

Do not smoke when using solvent. Failure to do so could

necessary, get medical attention. If contact with skin or

clothes is made, flush thoroughly with water. If the

solvent contacts your eyes, flush with water immediately,

and obtain medical aid (ref. FM 4.25--11).
