Checking The Spark Plug; Adjusting The Carburetor - EcoFlow Smart Generator User Manual

3.1 Checking the Spark Plug

The spark plug is an important part of the generator and must be checked regularly.
1. Turn the maintenance cover knob to
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 sufficient
clearance. If required, correct the gap.
Standard spark plug: A5RTC
Spark plug clearance: 0.15–0.3 mm
Tips: The engine may be damaged if the spark
plug is not at the correct clearance height.
6. Reinstall the spark plug with a torque of 13.5±1.5 Nm.
Tip: 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.

3.2 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.
Modifying the carburetor can improve its high altitude performance. If you plan to operate your generator at
high altitude (above 3000 feet/914 m) areas for a long time, please contact your after-sales service team to
help to modify it. When using the modified carburetor in high altitude areas (if within the service life of the
generator), the generator will satisfy every emission standard.
