Step 12. Add Fuel

DETONATION CAN OCCUR IF THE INCORRECT FUEL IS USED.
DETONATION CAN INCREASE ENGINE CYLINDER TEMPERAURE AND
PRESSURE AND CAUSE DAMAGE TO THE ENGINE.
Add the correct fuel. Refer to Appendix A or the latest revision of Service Instruction No. SI-1070
for approved fuels for this engine.

Step 13. Engine Pre-Oil Procedure

IF THE PRE-OIL PROCEDURE IS NOT DONE, HIGH-SPEED BEARING
FAILURE CAN OCCUR.
NOTICE: The purpose of the engine pre-oil procedure is to internally circulate oil through the
engine via a few turns of the engine propeller or crankshaft and ensure that oil pressure
is sustained which is an indication that there are no oil leaks.
Complete the engine pre-oil procedure on the engine at the following times:
 Before the initial start of a new, rebuilt, overhauled, or stored engine
or
 After oil cooler replacement-draining
or
 After any prolonged period of inactivity
or
 Whenever the oil lines have been disconnected. Disconnect the oil inlet connection at the oil
pump and drain a sufficient amount of oil from the tank to be certain there are no obstructions
or air in the inlet line to the oil pump.
To complete the pre-oil procedure:
1. Remove one spark plug from each cylinder of the engine per instructions in Chapter 74-20 of
the IO-360-N1A Engine Service Manual.
2. Remove and discard the spark plug gasket.
3. Make sure that the mixture control lever is in the IDLE CUT-OFF position.
4. Make sure the ignition switch is OFF and magneto P leads are grounded.
5. Make sure the fuel selector and fuel pump switches are in the OFF position.
6. Disconnect the fuel inlet lines.
7. Enable power to the engine.
