To insure that the engine generator set is ready for
operation at all times, it must be inspected systema-
tically so that defects may be discovered and cor-
rected before thay result in serious damage or fail-
ure. The necessary preventive maintenance services
to be performed are listed and described in para-
graphs 3-6 and 3-7.
Item numbers indicate the se-
quence of minimum inspection requirements. Defects
discovered during operation of the unit shall be noted
for future correction, to be made as soon as operation
has ceased. Stop operation immediately if a defi-
ciency is noticed which would damage the equipment
if operation were continued. Air Force users shall
refer to the applicable inspection manuals and work
card sets in T. O. 35C2-3-Series for periodic pre-
ventive maintenance requirements and table 3-1
for detailed procedures. Marine Corps users should
refer to the current issue of TM 11275-15/1.
