Furthermore, the evaporated (gasified) gasoline is highly explosive. Work in a well-ventilated areas.
● Exhaust gas contains poisonous substance. Do not keep engine running for a long period of time in a
closed, or poorly ventilated area.

● Do not excessively bend or twist cable. Distorted or damaged cable may lead to mechanical malfunctions.
● Pay particular attention to the position of O-ring. Replace with new ones when disassembled.
● If it is desired to store a vehicle for a period longer than 1 month, drain gasoline out of the carburetor float
