OIL CHANGE
It is recommended to ask authorized service for oil change.
Drain the engine oil when the engine is warm. Warm oil drains quickly and complete. Attention:
Do not drain oil when the engine is running!
When you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel can leak
out and result in a fire or explosion.
1. Disconnect the spark plug wire and keep it away from the spark plug.
2. Place a suitable container next to the engine to catch the used oil.
3. Remove the oil filler cap/dipstick (fig. 21A).
4. Remove the drain bolt (fig. 22A) and washer (fig. 22B) and allow the used oil to drain
completely into the container.
5. For engine without drain plug, we recommend to use oil extractor pump (fig. 23), or drain
the oil into the container by slightly tilting the engine toward the oil filler cap/dipstick. Before
tilting the machine, remove fuel from tank. Keep the spark plug end of the engine up.
Please dispose of used motor oil in a manner that is compatible with the
environment. We suggest you take used oil in a sealed container to your local
recycling center or service station for reclamation. Do not throw it in the trash or
pour it on the ground or down a drain.
6. Reinstall the drain bolt. With the engine in a level position, fill to the upper limit mark on the
dipstick with the recommended oil.
WARNING! Running the engine with a low oil level can cause engine damage.
7. Reinstall the oil filler cap/dipstick securely.
Warning!!! Wash your hands with soap and water after handling used oil.
AIR FILTER
A dirty air filter will restrict air flow to the carburetor and cause poor engine performance.
Inspect the air filter each time the engine is operated. You will need to clean the air filter more
frequently if you operate the engine in very dusty areas.
WARNING! Operating the engine without an air filter, or with a damaged air filter,
will allow dirt to enter the engine, causing rapid engine wear. This type of damage
