1-1.2. Advisories
This manual utilizes three types of advisories; defined as follows:
WARNING
A warning emphasizes information which, if disregarded,
could result in severe injury to personnel or equipment failure.
CAUTION: Emphasizes certain information or instructions, which if
disregarded, may result in damage to the engine or accessories.
NOTE: Provides special interest information, which may facilitate
performance of a procedure or operation of equipment.
Warnings and cautions precede the steps to which they apply; notes are placed in the
manner which provides the greatest clarity. Warnings, cautions and notes do not impose
undue restrictions. Failure to heed advisories will likely result in the undesirable or
unsafe conditions the advisory was intended to prevent. Advisories are inserted to ensure
maximum safety, efficiency, and performance. Abuse, misuse, or neglect of equipment
can cause eventual engine malfunction or failure.
1-1.3. Using this Manual
