ADULT SECTION

Operation

Fuel

When refueling, use either leaded or unleaded gasoline with a minimum 
pump octane number of 87=(R+ M)/2 octane. 

Do not use E-85 fuel.

WARNING

Gasoline is highly flammable and explosive under certain conditions.

• Always exercise extreme caution whenever handling gasoline.

• Always refuel with the engine stopped, and outdoors or in a well ventilated 

area.

• Do not smoke or allow open flames or sparks in or near the area where 

refueling is performed or where gasoline is stored.

• Do not overfill the tank. Do not fill the tank neck.

• If gasoline spills on your skin or clothing, immediately wash it off with soap 

and water and change clothing.

• If you get gasoline in your eyes or if you swallow gasoline, see your doctor 

immediately.

• Never start the engine or let it run in an enclosed area. Engine exhaust 

fumes are poisonous and can cause loss of consciousness or death in a 
short time.

• Turn the fuel valve off whenever the vehicle is stored or parked.

WARNING

The engine exhaust from this product contains chemicals known to cause 
cancer, birth defects or other reproductive harm. Operate this vehicle only out-
doors or in well-ventilated areas.
