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.
When you move the location of equipment
• Make sure that the fuel tank is EMPTY or that the fuel shut-off valve is in the
CLOSED position.
When fuel or equipment is in storage with fuel in the fuel tank
• Because pilot lights or other ignition sources can cause explosions, keep fuel or
equipment away from furnaces, stoves, water heaters or other appliances that
have pilot lights.
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
Engine start-up causes spark that could result in a fire or explosion.
• 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.

Authorized Service Dealer to correct the oil problem.
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) is permitted.
NOTICE
Do not use unapproved gasoline, such as E15 and E85. Do not mix oil in gasoline or
change the engine to operate on alternate fuels. Use of unapproved fuels could result in
damage to engine components, which will not be repaired under the warranty.
To protect the fuel system from gum formation, and corrosion, mix analcohol-free fuel
stabilizer and ethanol treatmentinto the fuel. Refer to the Storage section. All fuel is not
the same. If start or performance problems occur, change fuel providers or brands. This
engine is certified to operate on gasoline. The emissions control system for carbureted
engines is EM (Engine Modifications). The emissions control systems for engines with
electronic fuel injection are ECM (Engine Control Module), MPI (Multi Port Injection), and
if equipped an O2S (Oxygen Sensor).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON)
gasoline is permitted.
For carbureted engines, high altitude adjustment is required to maintain performance.
Operation without this adjustment will cause decreased performance, increased fuel
consumption, and increased emissions. Contact a Briggs & Stratton Authorized Service
Dealer for high altitude adjustment information. Operation of the engine at altitudes
below 2,500 feet (762 meters) with the high altitude adjustment is not recommended.
For Electronic Fuel Injection (EFI) engines, no high altitude adjustment is necessary.

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 in a fire or an explosion. If the engine is tilted
in a different direction, it will not easily start because of oil or fuel contamination of the air
filter or the spark plug.
WARNING
Accidental engine spark can cause an electric shock or fire and could result in
entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
• Disconnect all spark plug wires and keep them away from the spark plugs.
• Disconnect the battery wire from the negative battery terminal (only engines with
electric start).
• Use only the correct tools.
When you check for spark:
• Use an approved spark plug tester.
• Do not check for spark with the spark plug removed.
WARNING
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.
