Precautions in Operation
General information
Warning
● Gasoline is a low fire point and explosive material. Always work in a well-ventilated place and flame is
strictly prohibited when working with gasoline.
● Before dismantling fuel system parts, leak fuel out first, or grip the fuel pipe by using pliers to prevent
fuel from splashing.
Cautions
● Do not bend or twist the throttle cable. Damaged cable will lead to unstable driving.

re-assembly.
