RETURNING THE ENGINE TO
SERVICE
1. Perform the Daily Checks on page 49.
2. The engine should be pre-oiled before startup.
Crank the engine, leaving the fuel system shut
off so the engine will not start, for 15 seconds.
Then pause for 30 seconds. Repeat the
procedure until you have cranked the engine for
a total of one minute. This will circulate the oil in
the engine's lubrication system.
3. Prime the fuel system. See Priming the Fuel
System on page 42.
4. Start the engine. Allow the engine to idle for
approximately 15 minutes while you check for:
• Proper oil pressure
• Fuel, engine oil, or coolant leaks
• Proper operation of the indicators and/or
gauges.
5. Avoid prolonged operation at minimum or
maximum engine speeds and loads for the
remainder of the first hour of operation.
