6.3.2 Adjusting the Carburetor
The carburetor is an important part of the engine and should be adjusted by a
dealer with professional knowledge, data, and equipment to ensure proper
adjustment.
Notice:
In high-altitude areas, the atmospheric pressure may reduce the
amount of air intake, decline the performance, and increase the fuel
consumption of standard carburetors. Moreover, the dense mixture
may contaminate the spark plug and lead to starting difficulties.
When the generator is running at high altitudes (above 3000 feet /
914 m), the emissions may increase.
6.3.3 Replacing the Engine Oil
1. Place the generator on a level surface. Start the generator and let it run for
a few minutes to warm up the oil. Then, shut down the generator.
Note: The oil temperature will be very high. Take care to avoid burns when
draining the oil.
2. Use the screwdriver (Slotted-head) provided in the package to unscrew the
maintenance cover, and then remove the cover.
3. Remove the oil dipstick.
4. Place the oil basin under the generator and tilt the generator. The oil will
drain quickly.
Note: Improper disposal of engine oil can harm the environment. If you
replace the engine oil yourself, dispose of it properly. Store the used oil in a
sealed container and take it to a nearby oil recycling center. Do not pour it
into trash cans, onto the ground, or down the sewer.
5. Place the generator back in its original horizontal position.
6. Refill the oil to the proper level.
Note: Be careful to prevent any foreign objects from entering the engine.
7. Wipe the oil dipstick clean and remove any spilled oil.
8. Reinstall the oil dipstick.
