TEXTRON
LYCOMING OPERATOR'S
MANUAL
0-540 & 10-540 SERIES
SECTION 3
OPERATING INSTRUCTIONS
1. GENERAL.
Close adherence to these
instructions will greatly contribute
to long life, economy
and satisfactory operation
of the engine.
NOTE
YOUR ATTENTION IS DIRECTED TO THE WARRANTIES THAT
APPEAR IN
THE FRONT OF THIS
MANUAL REGARDING
ENGINE SPEED, THE USE OF SPECIFIED FUELS AND
LUBRICANTS,
REPAIRS AND
ALTERATIONS. PERHAPS
NO
OTHER ITEM
OF ENGINE OPERATION
AND MAINTENANCE
CONTRIBUTES
QUITE SO MUCH
TO SATISFACTORY PERFOR-
MANCE AND LONG LIFE AS THE CONSTANT USE OF CORRECT
GRADES OF FUEL AND OIL, CORRECT ENGINE TIMING, AND
FLYING THE AIRCRAFT AT ALL TIMES WITHIN THE SPEED
AND
POWER RANGE SPECIFIED
FOR THE ENGINE. DO
NOT
FORGET THAT
VIOLATION OF THE
OPERATION AND
MAINTENANCE SPECIFICATIONS FOR YOUR ENGINE WILL
NOT ONLY VOID YOUR
WARRANTY BUT WILL
SHORTEN THE
LIFE OF YOUR ENGINE AFTER ITS WARRANTY PERIOD HAS
PASSED.
New
engines have been carefully
run-in by Textron Lycoming
and
therefore, no further break-in is necessary insofar as operation is concerned;
however,
new or newly overhauled engines
should be operated using only
the lubricating oils recommended in the latest edition of Service Instruc-
tion No. 1014.
NOTE
Cruising
should be done at 65% to 75%
power until a total of 50 hours has
been
accumulated or the oil consumption
has stabilized. This is
to insure
the proper
seating of the
rings and is applicable
to new
engines and engines
in service
following
cylinder replacement
or top overhaul
of one or
more
cylinders.
The minimum
fuel octane rating
is listed in
the flight chart,
Part 9 of
this section.
Under no circumstances
should
fuel of a lower
octane rating
or
automotive
fuel (regardless
of octane
rating) be
used.
