INTRODUCTION
The Operating instructions outlined in this manual have
been developed from comprehensive evaluation
of the engine
performance in relation to its installation in an aircraft.
Recommendations, cautions and warnings regarding operation
of
this engine are not intended to impose undue restrictions on
operation
of the aircraft, but are inserted to enable the pilot to
obtain maximum performance from the engine commensurate
with safety
and efficiency. Abuse, misuse, or neglect of any piece
of equipment can cause eventual failure. In the case of an aircraft
engine
it should be obvious that a failure may have disastrous
consequences. Failure to observe the instructions contained in this
manual constitutes unauthorized operation in areas unexplored
during development
of the engine, or in areas in which experience
has proved
to be undesirable or detrimental.
Notes, Cautions and Warnings are included throughout this
manual. Application
is as follows:
NOTE: Special interest information which may facilitate the
operation
of equipment.
CA UTION: Information issued to emphasize certain instructions
or to preventpossible damage to engine or accessories.
WARNING: Information which, if disregarded, may
result in severe damage
to the engines and! or personal
injury.
Users are advised
to keep up with the latest information by means
of service bulletins, which are available for study at any approved
Teledyne Continental Distributor or Dealer, and are obtainable on
an annual subscription basis. Subscription forms are available from
the Distributor or from Teledyne Continental Motors, P. O. Box
90, Mobile, Alabama 36601, Attention: Publications Department.

WARNING: This engine must be installed in accordance
with all requirements
and limitations listed in the Detail
Specification forTeledyne Continental Aircraft Engines.
Any deviations caused
by installation, or operation,
such as acrobatic maneuvers will be deemed as misuse
and Teledyne Continental Motors shall be relieved of
any further responsibility.

SECTION I
OPERATING SPECIFICATIONS AND LIMITS
When increasing power, enrich mixture and advance
throttle in
that order. When reducing power, retard throttle, then adjust
mixture.
CA UTION ... Cylinder head and oil temperatures must never be
allowed to exceed the limitations specified. Near-maximum
temperatures should occur only when operating under adverse
conditions, such
as high power settings, low airspeed, extreme
ambient temperature, etc.
If excessive temperatures are noted, and
cannot reasonably be explained, or
if abnormal cowl flap and/or
mixture settings
are required to maintain temperatures, then an
inspection should be performed to determine the cause. Possible
causes
of high temperatures may include broken or missing baffles,
inoperative cowl flaps
(if applicable), or restricted fuel inlets
(resulting in lean-running cylinders). Faulty instruments or
thermocouples may cause erroneously high (or low) temperature
indications.
Refer to Section VIII of this manual and/or the
aircraft overhaul manual
for trouble shooting procedures.
WARNING. . .Do not use any propeller that is not
certificated and specifically designed for operation on
this engine.

SECTION II
NORMAL OPERATING PROCEDURE
CA UTI ON ... This section pertains to operatioll IIl1der aJ'erage
climatic conditions. The pilot sllOuld tllOrollghly familiari::e
himself with Section V, Abnormal Operatillg COlldirol1s. TI'hel1el'er
such abnormal conditions are ellCOIIII tered or ,111 ticipated, the
procedures and techniques for normal operatioll shollld be tailored
accordingly. For example, if the aircraft is to be temporarily
operated in extreme cold or hot weather, cOllsideratiOiI shollid be
given to an early oil change and/or a rou tine illspectioll sen'icillg.
GENERAL.
The life of your engine is determined by the care it receives.
Follow the instructions contained in this manual carefully.
The engine receives a run-in operation before leaving the factory.
Therefore, no break-in schedule need be followed. Straight mineral
oil (MIL-C-6529 Type II) should be used for the first oil change
period (25 hours).
The minimum grade aviation fuel for this engine is 80/87. In case
the grade required is not available, use a higher rating. Ne\"er use a
lower rated fuel.
WARNING ... The use of a lower octane rated fuel can
cause pre-ignition
and/or detonation which can damage
an engine the first time high power is applied. This
would most likely occur on takeoff. If the aircraft is
inadvertently serviced with the wrong grade of fuel,
then the fuel must be completely drained and the tank
properly serviced.
11

12
PRESTARTING.
Before each flight the engine and propeller should be examined for
damage, oil leaks, security
and proper servicing.
1. Position the ignition switch to the "OFF" position.
2. Operate all controls and check for binding and full range of
travel.
3. Assure
that fuel tanks contain proper type and quantity of
fuel.
4. Drain a
quantity of fuel from all sumps and strainers into a
clean container.
If water or foreign matter is noted, continue
draining until only clean fuel appears.
5. Check oil level in sump.
6., Check cowling for security.
STARTING
1. Fuel Selector -On.
2. Battery Switch -On.
3. Ignition Switch -On.
4. Mixture -Full Rich.
5. Throttle -Full Open.
6. Prime -Operate 3 to 5 strokes.
NOTE . . . The
amount of prime required depends on engine
temperature. Familiarity and practice will enable the
operator to
