Make sure there is sufficient fuel in the tank. Refuel if necessary.
Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, follow these instructions.
Before refueling, turn off the engine and be sure that no one is sitting in the vehicle.
Never refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition such as the pilot lights of water heaters and clothes dryers.
Do not overfill the fuel tank. Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank.
Wipe up any spilled fuel immediately.
Be sure the fuel tank cap is closed securely.
Gasoline is poisonous and can cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.
Use premium unleaded gasoline of [R+M]/2 octane 91 or higher, which is equivalent to RON 95 or higher. If knocking or pinging occurs, try a different brand or higher octane gasoline. Unleaded fuel will give you longer spark plug life and reduced maintenance cost. Gasoline containing ethanol can be used if the ethanol content does not exceed 10% (E10). Gasoline containing methanol is not recommended because it can cause damage to the fuel system or vehicle performance problems.
Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as the valves and piston rings, as well as to the exhaust system.
If you carry a portable fuel container in the bed of your Yamaha Wolverine RMAX4, be sure to secure it with the cap tightened before driving the vehicle.
Always place a portable fuel container on the ground before filling it. Before removing the container cap, touch the container with the fuel dispenser nozzle. Keep fuel dispenser nozzle in contact with container inlet when filling. WARNING! Never refill a fuel container in the bed of any vehicle. Fire may result from a build-up of static electricity. The discharge of this build-up while refueling can cause a spark and ignite the gasoline.
