Checking the Spark Plug
The spark plug is an important part of the generator and must be checked regularly.
1. Use the provided screwdriver to loosen and remove the bolt securing the top maintenance cover.
2. Take off the spark plug cap.
3. Use the spark plug socket and revolve it counterclockwise to remove the spark plug.
4. Check for any fading in color and remove any carbon deposits. The porcelain center around the spark plug center
electrode should be moderately light brown if it is in good condition. The electrode should be replaced if worn, or
if the insulation is peeling, cracked or dirty.
5. Check the model of the spark plug and that it has sufcient clearance. If required, correct the gap.
6. Reinstall the spark plug with a torque of 22±2(N ×m).
Note: If installing without a torque wrench, a good method is to tighten until tight, then continue to turn by a
further 1/4-1/2 rotation.
7. Reinstall the spark plug cap on the spark plug.
8. Reinstall the maintenance cover.
Adjusting the Carburetor
The carburetor is an important part of engine, and should be adjusted by the dealer who has the professional
knowledge, data and equipment to ensure it is adjusted correctly.
Usage in high altitude areas
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.
Replacing the Engine Oil
• Do not drain the engine oil immediately after the generator is switched off. The oil temperature
will be very high. Please take care not to get scalded when draining the oil.
• Prevent any foreign objects from entering the inside of the engine.
• Do not tilt the generator when adding engine oil to prevent damage to the generator due to
adding excessive oil.
1. Place the generator on a level plane, start it up and keep it running for several minutes to increase its temperature.
Then turn it off. Turn the Engine Switch to “OFF”.
2. Use the provided screwdriver to loosen the bolts of the maintenance cover, and then remove it.
3. Loosen the lid and 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 may harm the environment. If you replace the engine oil yourself, please
dispose of the used oil properly. Store the used oil in a sealed container and take it to your nearest oil recycling
center. Do not pour it into any trash can, onto the ground or into the sewer.
