To attach the Azimuth Control to your wedge

follow these steps:
-

To assemble
the
equatorialwedge,
follow this procedure
(note
that all
required wedge hardware and manual
knobs are shipped within the wedge carton):
1.
The wedge consists
of two basic
parts:
the wedge body and the tilt-plate, as shown in Fig.
3.
Attach the
tilt-plate to the
wedge body by threading in the four knobs provided. Two knobs, with washers, should be
used on each side of
the
wedge body so that
a
total of 4 knobs attach the tilt plate to the wedge
body.
NOTE: When installing
the tilt-plate to the
wedge,
note that it is
a
tight fit
and the sides must
generally spread
slightly
to
accept the tilt-plate. lf the main crossbar
of
the Deluxe Latitude Adjuster is already tightened into
place this
will inhibit
your
installatlon of the tilt-plate. You
will
therefore see that by releasing the screws
on
the ends of the DLA crossbar (#6, Fig.
3)
your
installation
of
the wedge tilt-plate will be facilitated.
2.
Place the wedge onto the field tripod with the central threaded rod
of
the tripod fitting through the center
hole
in the
floor
of the
wedge. Thread the wedge knob (#9, Fig.
9) onto
the threaded rod of the field tripod
and firmly tighten the
manual knob.

2) Detuxe Latitude Adjuster
The Deluxe Latitude Adjuster (DLA) attaches directly to the
Equatorial
Wedge and permits very
precise
adjustments in latitude angle by the simple turning
of
one knob.
The
Equatorial Wedge
for
Meade 8'Schmidt-Cassegrain telescope
is
shipped with the main crossbar
(#5,
Fig.
1
1) of
the
DLA already installed. Loosen the two socket-head screws
that
lock
the
main crossbar
in place, to allow the crossbar to rotate slightly if needed. Thread the long adjustment knob (#3, Fig.
1
1) into
the main crossbar and position the end of the adjustment knob into the cavity on the underside of
the
Equatorial Wedge Tilt-Plate. Tighten the two socket-head screws locking the main crossbar into
place.
The DLA is now ready to use. To
make
fine latitude adjustments, follow this procedure:
1
.
Slightly loosen the knobs (#5, Fig. 3), on each side
of
the wedge.
2.
Turn the DLA's adjustment knob (pressing against the bottom
of the tilt-plate), so that the
tilt-plate
moves
in latitude angle.
3. Re-tighten
he
two knobs, which were loosened in step
1, above.
