CAUTION TO MECHANICS
Machines of Class 251- are made with extreme precision in ma-
chining and assembly, and the "Superfinish" process provides mi-
croscopically smooth bearing surfaces. Therefore, special care should
be taken not to permit any misalignment or cause any scratches or
nicks on the bearing surfaces by careless assembly or handling of
parts. Any such damage might render the machine incapable of the
long trouble-free service for which it is designed.
