This manual is part of the interface control document for IO-240-A and B engine models.
This manual provides airframe interface requirements, installation instructions and engine
operating instructions to supplement the Airplane Flight Manual (POH)/Pilot’s Operating
Handbook (POH).
Instructions in this manual are specific to the IO-240 Series engines. For information
specific to other Continental Motors engine series, accessories, or the airplane, refer to the
appropriate manual. Chapters are arranged in sequential order to install, test, and operate
the engine.

peculiar information pertains to only a specific engine model in the series, an effectivity
symbol will accompany the information. Effectivity symbols found in this publication are:

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
Except for engine installation drawings, illustrations in this manual are for reference only,
depicting the most prominent configuration in the engine series. Consult the parts catalogs
for engine model-specific illustrated parts breakdowns.
