1. Check engine oil level before each use and maintain oil level to the full mark on the dipstick. See section titled
"Checking and Adding Engine Oil" on page 13.
2. Service air filter every 25 hours under normal conditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced.
Never run the engine without an air filter installed. Running the engine without the filter can cause excessive
engine wear and damage.
3. Clean engine regularly with a cloth or brush. Keep the top of the engine free of debris to permit proper air
circulation. Remove all grass, dirt and combustible material from muffler area.
