Before you start
- Do not overfill above the high mark; engine oil may blow out and component parts are adversely affected by oil temperature rise
Procedure
- Remove the cap from the oil filler.
- Fill the engine oil pan with specified engine oil to the specified level.
- Remove the rocker cover and pour engine oil into the valve mechanism and camshaft oil bath.
- Reinstall the rocker covers.
- Check the oil level using the oil level gauge; proper level is between high and low marks.
- Crank the engine (pulling stop lever) for approx. 10 seconds, 2-3 times, to circulate oil.
- Start the engine and run at low idle, no load, for 5 to 10 minutes.
- Recheck oil level after leaving the engine stopped for 30 minutes or more; add oil as needed.
