Recommended fuel
It is recommended to use the unleaded gasoline with an octane value of 90# or higher, so
as to reduce the carbon deposition in the combustion chamber.
Do not use the out-of-date or polluted gasoline or the fuel mixture of engine oil and gasoline.
It is also required to keep the water or dust from getting into the fuel tank.
Sometimes, there will be spark knock sound or the bang-bang noise in case of overload
operation, which is normal.
If the continuous spark knock sound can still be heard when the gasoline engine operates
under the normal load, it is suggested to replace the gasoline with other brands; after then,
if the sound still exists, please consult the specially authorized service shop for solution
