Note: I The first oil change should be carried out after 5 operating hours, when operating
under heavy load another change should be done after 25 operating hours.
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. Place a suitable container next to the engine to catch the used oil (pic. 17 A).
2. Remove the oil filler cap/dipstick.
3. Remove the drain bolt - if equipped - and allow the used oil to drain completely into
the container.
4. For engine without drain plug, we recommend to use oil extractor pump, 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. Do
not drain oil from the upper filler neck unless the fuel tank is completely empty.
Otherwise when the machine is tilted, fuel might leak and cause fire or explosion.
5. Reinstall the drain bolt. With the engine in a level position, fill to the upper limit mark on
cap/dipstick.
6. Reinstall the oil filler cap/dipstick securely (pic. 17 A).
Note: I 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.
• Running the engine with a low oil level can cause engine damage.
• 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.
Note: I 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 is not covered.
AIR FILTER INSPECTION AND CLEANING
CAUTION! A
The air filter must be serviced (cleaned) after 25 hours normal working. Service more
frequently when operating the machine in extremely dusty areas.
Shut off the engine before performing any service on the machine. Wait till all moving
parts are completely stopped and disconnect the spark plug.
1. Release the air filter cover (pic. 18 A).
2. Remove the air filter cover. Be careful to prevent dirt and debris from falling into the air
filter base.
