TM 1-4920-455-13&P
SECTION Ill. PRINCIPLES OF OPERATION
1-8. After the shelter has been expanded, the operator will unbolt selected items of equipment. These items will
be moved to recommended positions on the expanded side of the shelter (see para., 1-7b). The selected items, when
moved, will not be secured (bolted) in place. This allows the shop personnel a certain flexibility in the event long or
bulky material must be repaired within the shelter. The recommended locations were selected for proper utilization
of floor space and maximum safety for the operating personnel.
1-9. Detailed instructions for unbolting equipment and the recommended sequence for movement are contained
in Chapter 2, Section II. Supplemental procedures for opening and closing the shelter are contained in Chapter 2,
Sections I and III. TM 10-5411-201-14 is required for detailed instructions.
1-10. Electrical power to operate the Welding Shop is provided by a generator or a commercial power source. A
power distribution panel (PDP) is used between the power source and the power entry panel of the shelter. Overload
protection is provided by circuit breakers.
