                        BEFORE OPERATION  Check the Engine  l Check the engine oil level (see page 23). Running the engine with a low oil  level can cause engine damage.  l Check the air filter (see page 29). A dirty air filter will restrict air flow to the  carburetor, reducing engine performance.  l Check the fuel level. Starting with a full tank will help to eliminate or reduce  operating interruptions for refueling.
