53A>1 Install the unthreaded backing flange  on
spindle  with the raised section (pilot) against the
wheel.

wheel on the raised section (pilot) of the backing flange.
53A>1 While depressing the spindle lock button,
thread the threaded clamp nut  on spindle.
53A>1 If the wheel you are installing is more
than 1/8 inch (3mm) thick, place the threaded
clamp nut on the spindle so that the raised section
(pilot) fits into the center of the wheel.
53A>1 If the wheel you are installing is 1/8 inch
(3mm) thick or less, place the threaded clamp nut
on the spindle so that the raised section (pilot) is
not against the wheel.
 While depressing the spindle lock button  tighten the
threaded clamp nut with included wrench.
 To remove the wheel, depress the spindle lock button
and loosen the threaded clamp nut with included wrench.
!;@1 If the wheel spins after the threaded clamp nut is
tightened, check the orientation of the threaded clamp nut.
If a thin wheel is installed with the pilot on the clamp nut
against the wheel, it will spin because the height of the pilot
prevents the clamp nut from holding the wheel.
