Bolt Tightening
Tightening of the base plate
mounting bolts directly affects
vertical arm alignment and base
plate warpage. Tighten inside
mounting bolts first, then tighten
outside mounting bolts. Measure
alignment of towers and vertical
arms while tightening. See Figure
M.
Note:
Towers must be aligned
and parallel, with platform side
plates securely nested in the
guided stow blocks. See Photos A
and B.
Mounting Bolt Torque Speci-
fications:
28 to 31 foot
pounds. Adjustment to mount-
ing bolt torque may be required
to achieve proper alignment.
