Safety Messages

WARNING 

Briggs & Stratton® Engines are not designed for and are not to be used to power:

fun-karts; go-karts; children's, recreational, or sport all-terrain vehicles (ATVs);

motorbikes; hovercraft; aircraft products; or vehicles used in competitive events not

sanctioned by Briggs & Stratton. For information about competitive racing products, see

www.briggsracing.com. For use with utility and side-by-side ATVs, please contact Briggs

& Stratton Power Application Center, 1-866-927-3349. Incorrect engine use could result

in serious injury or death.

WARNING 

Fuel and its vapors are flammable and explosive. Fire or explosion could result in

burns or death.

When you add fuel

•

Stop the engine. Before you remove the fuel cap, wait a minimum of two (2)

minutes to make sure that the engine is cool.

•

Fill the fuel tank outdoors or in an area that has good airflow.

•

Do not put too much fuel in the tank. For expansion of the fuel, do not fill above

the bottom of the fuel tank neck.

•

Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition

sources.

•

Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks

or leaks. Replace damaged parts.

•

If fuel spills, wait until it dries before you start the engine.

When you start the engine

•

Make sure that the spark plug, muffler, fuel cap and air cleaner (if equipped) are

correctly installed.

•

Do not crank the engine with the spark plug removed.

•

If the engine is flooded, set the choke (if equipped) to the OPEN or RUN

position. Move the throttle (if equipped) to the FAST position and crank until the

engine starts.

•

If there is natural or LP gas leakage in the area, do not start the engine.

•

Because vapors are flammable, do not use pressurized starter fluids.

When you operate the equipment

•

Do not tilt the engine or the equipment at an angle which causes fuel to spill.

•

Do not choke the carburetor (if equipped) to stop the engine.

•

Do not start or operate the engine with the air cleaner (if equipped) or the air

filter (if equipped) removed.

When you do maintenance

•

If you drain the oil from the top oil fill tube, the fuel tank must be empty. If it is not

empty, fuel leakage can occur and could result a fire or an explosion.

•

During maintenance if it is necessary to tilt the unit, make sure that the fuel tank,

if mounted on the engine, is empty and that the spark plug side is up. If the fuel

tank is not empty, leakage can occur and could result a fire or an explosion.

•

Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks

or leaks. Replace damaged parts.

•

Do not change the governor spring, links or other parts to increase engine

speed.

•

Do not hit the flywheel with a hammer or hard object. This could result in failure

of the flywheel during operation.

•

Replacement parts must be of the same design and installed in the same

position as the original parts. Other parts could result in damage or an injury.
