are 2 bolts in the rear of the pedestal that slide into
the 2 slotted holes in the rear of the enclosure.
Position the drive by adjusting the bolts up or down.
Loosely secure with 2 M10 nuts and locking brackets.
See Illustration 1.5.
2. Around the top of the pedestal, secure the enclosure
using 6 M10x30 fasteners. See Illustration 1.6. Loosely
tighten each bolt until all bolts are installed.
3. Fasten each bolt securely and torque to 19 Nm (169
in-lb).
4. Torque the 2 M10 nuts at the rear of the enclosure to
19 Nm (169 in-lb).
