3279 Color Display Station Parts Catalog 2
HOW TO USE THIS PARTS CATALOG
This catalog is divided into three major sections:
The Visual Index contains small overall views of the
machine, and gives references for all the major assemblies
which are broken down in the Group Assembly Parts list
(GAPL).
The Group Assembly Parts List contains exploded
illustrations of the assemblies, subassemblies, and detail
parts of the machine. Parts are cross·referenced by index
number to the list of part numbers that accompanies each
figure.
The Numerical Index follows the GAPL. It contains all of
the part numbers on the GAPL in numerical order. and
cross-references them by figure and index number.
Finding a Part
Turn to the visual index and find the general area of the
machine in which the part is located. An arrow from that
area will point to one or more reduced GAPl figures. Find
the figure or figures containing the part required; there is a
cross reference to indicate which GAPl figure contains the
part.
Turn to the referenced figure in the GAPL to find the
index -number of the part required and locate the index
number on the accompanying list. The list contains the
following details:
• Part Number
• Description
(Trailer lines after the description are used for clarification or to
indicate usage or obtainability of parts.)
• Units per Assembly
(This refers to the number of units used in the area indexed, or
the number used for a similar· purpose in the assembly.)
Circled Index Numbers
A circled index number indicates that the assembly is
broken down within the figure.

will be
supplied. If only the subassembly is required, order part
number 5357050; it will include all of the two-dot items
that immedi,tely follow its attaching parts. Attaching parts
must be ordered separately.
All parts may be ordered individually.
