LYCOMING OPERATOR'S MANUAL
O-235 AND O-290 SERIES
1. GENERAL. Close adherence to these instructions will greatly contribute to long life, economy and
satisfactory operation of the engine.
YOUR ATTENTION IS DIRECTED IN PARTICULAR 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 PREFORMANCE AND LONG LIFE AS THE
CONSTANT USE OF CORRECT GRADES OF FUEL AND OIL, CORRECT ENGINE
TIMING, AND FLYING THE AIRPLANE 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.
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 rings and is applicable
to new engines, and engines in service following cylinder replacement or top overhaul at one
or more cylinders.
The minimum fuel octane rating is listed in the Flight Chart, Part 8 of this section. Under no
circumstances should fuel of a lower octane rating or automotive fuel (regardless of octane rating) be used.
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 PROCEDURE.

a. Perform pre-flight inspection.
b. Head airplane into wind.
c. Lock wheels by either wheel brakes or chocks.
d. Set carburetor heat control in "cold" position.
