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 PERFORMANCE 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 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 revision of Service Instruction No. 1014.
NOTE
Cruising should be done at 65% to 75% power until a total of 50 hours has accumulated or
oil consumption has stabilized. This is to insure proper seating of the piston 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. Personnel
should be familiar with the latest revision of Service Instruction No. 1070.
2. PRESTARTING ITEMS OF MAINTENANCE. Before starting the aircraft engine for the first flight of the
day, there are several items of maintenance inspection that should be performed. These are described in
Section 4 under Daily Pre-Flight Inspection. They must be observed before the engine is started.
3. STARTING PROCEDURES (NORMAL).
a. Carbureted Engines.
(1) Perform pre-flight inspection.
(2) Carburetor heat “cold”.
(3) Turn fuel valve on.
