IO-360-N1A Engine Installation and Operation Manual
NOTICE: A low battery, engine speed less than 50 rpm, or sub-zero temperatures can prevent
engine start. Refer to the section "Apply Heat to a Cold Engine" in the "Engine
Conditions" chapter.
11. Energize the starter (not to exceed 10 seconds) until the engine starts.
12. Put the magneto switch in the BOTH position.
13. Move the throttle slowly and smoothly to the IDLE rpm.
14. Look at the oil pressure gage for indicated pressure. If there is no oil pressure indication
within 10 seconds, stop the engine. Identify and correct the problems.
NOTICE: Unstable oil pressure or oil pressure less than 25 psi (172 kPa) could be an
indication of obstructed or interrupted oil flow or air in the oil lines. In this case,
stop, identify and correct the cause.
NOTICE: Upon engine start, if smoke comes from a newly installed engine, after the first start,
there could have been some preservative oil in the cylinders, induction system,
and/or fuel nozzles/lines. If oil pressure is normal and the engine operates smoothly,
continue to operate the engine until the smoke clears. Otherwise, stop the engine and
identify the cause.
15. Let the engine operate at 1000 rpm for approximately 3 minutes.
NOTICE: Aircraft with fixed pitch propellers, or those that do not have a manifold pressure
gage, can complete magneto drop-off with engine operating at approximately 2100
to 2200 RPM.

DO NOT ENERGIZE THE STARTER FOR PERIODS OVER 10
SECONDS. LET THE STARTER COOL FOR 30 SECONDS AFTER
EACH ENERGIZATION. IF THE STARTER FAILS TO ENERGIZE
AFTER TWO ATTEMPTS, IDENTIFY AND CORRECT THE CAUSE. DO
NOT TRY MORE THAN FIVE ENGINE STARTS WITHIN A 2-MINUTE
PERIOD.
DO NOT EXCEED THE IDLE RPM (SET BY THE AIRCRAFT
MANUFACTURER) UNTIL THE OIL PRESSURE IS STABLE ABOVE
THE MINIMUM IDLING RANGE. IF THE OIL PRESSURE DOES NOT
INCREASE TO THE MINIMUM PRESSURE WITHIN 10 SECONDS,
STOP THE ENGINE. IDENTIFY AND CORRECT THE CAUSE. REFER
TO THE "ENGINE CONDITIONS" CHAPTER IN THIS MANUAL.
DO NOT OPERATE THE ENGINE IF THE OIL PRESSURE IS LOW. IF
THE ENGINE IS OPERATED AT LOW OR NO OIL PRESSURE, THE
ENGINE CAN MALFUNCTION OR STOP.
DO NOT OPERATE THE ENGINE AT SPEEDS ABOVE 2500 RPM
UNLESS THE OIL TEMPERATURE AND THE OIL PRESSURE ARE AT
LEAST THE MINIMUM SPECIFIED IN APPENDIX A FOR INITIAL
START. ENGINE DAMAGE CAN OCCUR IF THE OIL TEMPERATURE
OR OIL PRESSURE IS NOT AT THE SPECIFIED MINIMUM LEVELS.
