storage drawers, shock mounts, casters, shafts, adjustable couplings. The level of detail shall
be equal to the text descriptions. Illustrations of fully assembled major units and partially
assembled major units shall be supported by multiple callouts to provide as much coverage as
possible. Separate illustrations of individual subunits shall be included only if unique physical
features exist. Figure 18-4 is an example of the type of illustration required. For complex
equipment, illustrations showing overall general arrangements, such as shown in figure 18-5,
shall be provided with appropriate supporting notes.
3.6.3 Chapter 2, Operation. Operating instructions shall include all the procedures necessary to

d. When more than one operator is required to operate the equipment, his designated position
and function, and the relationship to his controls and indicators shall be specified.
3.6.3.3 Operating procedures. Operating procedures shall include the following:
a. Operator turn-on. All steps necessary to bring the equipment from OFF through STANDBY
condition to full operation.
b. Modes of operation. Procedures for each mode of operation, for example, manual, automatic,
