The fuel containing alcohol
If you decide to use the fuel containing alcohol (bioethanol), its octane value can
not below the level recommended by manufacturer. There are two kinds of
alcoholic fuel: one contains ethanol, and the other contains methanol.
Do not use the kind of alcoholic fuel that contains more than 10% ethanol.
Do not use the alcoholic fuel which has a content of over 5% methanol.
WARNING:
The damage of fuel-burning system and the performance problem of the
engine caused by using the alcoholic fuel will not be included in the warranty.
The manufacturer will not guarantee the use of fuel containing methanol, as its
applicability has not been confirmed.
Before you buy fuel at unfamiliar fuel stations, first try to know whether the
fuel contains alcohol or not. If it contains, confirm its type and the proportion of
alcohol in it. If the fuel you use contains alcohol or you think it contains alcohol,
and unexpected situations occurred during the running process, please change
to use the fuel without alcohol.
3. check the air filter
Check the core of the air filter, ensuring that it is clean and performs well.
Dismantle the repair cover, loosen the screw on the cover of the air filter, and
then dismantle the cover of the air filter to check the core.
Please clean or change the core if necessary.
Look out
Do not run the engine without the air filter, or else filth will enter the engine
through carburetor, resulting in quick wear and tear of the engine.
