OIL CHANGE
It is recommended to ask authorized service for oil change.
Note: I
The first oil change should be carried out after 5 operating hours, when operating
under heavy load another change should be done according to schedule (Maintenance
program).
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!
DRAINING OLD OIL
1. Prepare a suitable oil collection container next to the engine.
2. Remove the oil filler cap/dipstick (fig. 30A).
3. Remove the drain bolt and allow the used oil to drain completely into the container.
4. For engine without drain plug, we recommend to use oil extractor pump (fig. 31). Keep
the spark plug end of the engine up.
5. Reinstall the drain bolt. With the engine in a level position, fill to the upper limit mark on
the dipstick with the recommended oil.
6. Reinstall the oil filler cap/dipstick securely.
OIL FILTER REPLACEMENT (if installed)
1. Remove the oil filter.
2. Before you install the new oil filter, lightly lubricate the oil filter gasket with fresh,clean oil.
3. Install the oil filter by hand until the gasket contacts the oil filter adapter, then tighten the oil
filter 1/2 to 3/4 turns.
POURING NEW OIL
1. Clean the oil fill area of any debris.
2. Pour the oil slowly into the engine oil fill. Do not overfill. After adding oil, wait one minute
and then check the oil level.
C Do not add oil at the quick oil drain.
3. Check the oil level continuously with the dipstick.
4. Install and tighten the dipstick.
Note: I Dispose of the oil and filter in a manner that complies with applicable laws, do not
harm 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 and
increases fuel consumption. 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.
