If the engine oil level is above the Full mark,
change the engine oil.
The best time to check the engine oil is when the
engine is cool before it has been started for the day.
If it has already been run, allow the oil to drain back
down to the sump for at least 10 minutes before
checking. If the oil level is at or below the Add mark
on the dipstick, add oil to bring the oil level to the Full
mark. Do not overfill the engine with oil.
Important:
Keep the engine oil level between the
upper and lower limits on the dipstick; the engine
may fail if you run it with too much or too little oil.
1. Park the machine on a level surface.
2. Check the engine-oil level
