ENGINE MAINTENANCE
SAFETY PRECAUTIONS
• Make sure the engine is off before you begin any maintenance or repairs. This will eliminate
several potential hazards:
- Carbon monoxide poisoning from engine exhaust - be sure there is adequate
ventilation whenever you operate the engine.
- Burns from hot parts - let the engine and exhaust system cool before touching.
- Injury from moving parts.
• Read the instructions before you start the engine.
• To reduce the possibility of fire or explosion, be careful when working around gasoline. Use only
a nonflammable solvent, not gasoline, to clean parts. Keep cigarettes, sparks and flames away
from all fuel related parts.
• Remember that an authorized servicing dealer of our company knows Your engine best and is
fully equipped to maintain and repair it. To ensure the best quality and reliability, use only new
genuine our parts for repair and replacement.
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!
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. 39A).
4. Remove the drain bolt 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. 40A). 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.
