check that the lower surface of the roller does
not come in contact with the surface B of the

the threading ring pushes certainly the roller
of the lock arm assembly, and also check that
the pin of the lock arm assembly pushes
certainly the drawer guard.
(3) When the threading ring rotates toward the
unthreading end direction, check that the
roller of the T drawer assembly moves inside
to the threading ring smoothly. And at this
time, check that the lower surface of the
roller does not come in contact with the
surface B of the threading ring (shaded
portion in the figure). (Specification 2)

the height and the vertical play of the T
drawer arm. (Refer to T drawer arm height
