30 CFR § 7.108
Power package checklist.
Each diesel power package bearing an MSHA approval plate shall be
accompanied by a power package checklist. The power package checklist
shall consist of a list of specific features that must be checked and
tests that must be performed to determine if a previously approved
diesel power package is in approved condition. Test procedures shall be
specified in sufficient detail to allow evaluation to be made without
reference to other documents. Illustrations shall be used to fully
identify the approved configuration of the diesel power package.
