Before each use, look around and underneath the engine for signs of oil or
gasoline leaks.
1. Check the engine oil level.
Every 10 hours, check the engine oil level and replenish oil up to the upper limit if
the pump is operated for more than 10 hours continuously.
CAUTION:
Engine oil is a major factor affecting engine performance and service life.
Nondetergent or vegetable oils are not recommended.
Check the engine oil level with the engine stopped and in a level position.
1. Remove the oil filler cap.
2. Check the oil level. If it is below the upper limit, fill with the recommended oil
(see page 12) to the upper limit.
3. Reinstall the oil filler cap securely.
Add the engine oil slowly to avoid overflowing, as the engine oil tank capacity is
small.
CAUTION:
• Running the engine with insufficient oil can cause serious engine
damage.
• Be sure to check the engine on a level surface with the engine stopped.
