To insure that theload bank kit is ready for operation
at all times, when installed on the generator set, it
must be inspected systematically so that defects may
rediscovered andcorrected before they result in
serious damage or failure. Defects discovered ciur-
ing operation of the kit shall be noted for future cor-
rection, to be made as soon as o?eration has ceased.
Stop operation immediately if a deficiency is noted
during operation which would damaget hekit or the
end item generator to which it is attached. All de-
ficiencies and shortcomings SHALL be recorded to-
gether with thecorrective action on the applicable
form at the earliest possible opportunity. Air Force
users shall refer to the applicable inspection manuals
and work carcl sets in the T . O . 3 5 C 2 - 3 - Series for
periodic preventive maintenance requirements and
