
Gasoline is extremely flammable and is explosive under certain conditions.

Only add fuel in a well-ventilation area with the engine stopped. Do not smoke and do not allow flames or sparks in the area
where gasoline is stored or where the fuel tank is refueled.
 Do not overfill the fuel tank (there should be no fuel in the filling neck). After refueling, make sure the fuel tank cap is installed
securely.

Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area
cleaned up and is dry before starting the engine.

Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of reach of children.
3. FUEL RECOMMENDATION
1. Remove the fuel tank cap and check the fuel level.
2. If the level is too low, refuel the tank to the recommended level. Remember to never add fuel over the fuel filler shoulder.

 Fuel may damage the paint and plastic. Be careful not to spill fuel when refueling. Any damage due to fuel spilling is not
covered under warranty.

It is normal to hear a "Light knocking" or "spark exploding" sound when the engine is overloaded. Do not be concerned if this
occurs. If "knocking" or "spark exploding" sounds occur at a steady speed under normal load, change the brand of gasoline; if
the sounds continue, consult your dealer for help..

If you continue to run the engine with a "Knocking" or "spark exploding" sound during normal operation, it will damage the
engine.
 Continuing to use the engine with "Knocking" or "spark exploding" sounds from misusing will void the engine warranty.
