(1)
Assemble the front and rear right-hand brackets to the right-hand slide assembly;
assemble the front and rear left-hand brackets to the left-hand slide assembly.
The bracket screw heads must
be
ins~alled
on
the track side
of

will therefore appear on the bracket side,
or
outside,
of
the slide assembly. Use
lock washers under the nuts.
(2)
Install the right and left slide assemblies to the front and rear
EIA
rails. Adjust the
distance between the
slide brackets to 451.6 mm (17.78 inches). Ensure that the
right front and rear
slide brackets,
as
well
as
the left slide brackets, are installed
at the same height
on
the front
and
rear rails.
The
screw heads must
be
on the
outside of the
EIA
rails.

Pull the smaller chassis slide member forward to expose the screw holes that will
be
used to attach the small sl ide member to the disk chassis.
