THE POWER IN POWER EQUIPMENT  Thank you for selecting a Briggs & Stratton engine to power your equipment . Briggs & Stratton is committed to producing a line of engines which will make your life’s chores easier to perform . We have , at the same time , improved the design of our engines so they are environmentally friendly . Since 1995 , we have succeeded in reducing smog - forming exhaust emissions from our engines by 70 % . Briggs & Stratton’s efforts have not stopped there . We are also committed to designing and introducing even cleaner engines in the future , while maintaining our reputation for excellent utility and value . Briggs & Stratton’s environmental awareness has resulted in the engineering of the “ Smart - Fill  � gas can , featuring a spill resistant nozzle which opens only when fully inserted into the gas tank , and which shuts off automatically when the tank is full . Because refueling spills can harm the environment , the Smart - Fill  container helps preserve a stronger ecosystem by reducing this source of pollution . We hope you will enjoy your new engine and equipment . We welcome you to our worldwide family of Briggs & Stratton engine users . Best Wishes Always , The Employees of Briggs & Stratton Corporation Look For Relevant Emissions Durability Period and Air Index Information On Your Engine Emissions Label Engines that are certified to meet the California Air Resources Board ( CARB ) Tier 2 Emission Standards must display information regarding the Emissions Durability Period and the Air Index . Briggs & Stratton makes this information available to the consumer on our emission labels . The Emissions Durability Period describes the number of hours of actual running time for which the engine is certified to be emissions compliant , assuming proper maintenance in accordance with the Operating & Maintenance Instructions . The following categories are used : Moderate : Engine is certified to be emission compliant for 125 hours of actual engine running time . Intermediate : Engine is certified to be emission compliant for 250 hours of actual engine running time . Extended : Engine is certified to be emission compliant for 500 hours of actual engine running time . For example , a typical walk - behind lawn mower is used 20 to 25 hours per year . Therefore , the Emissions Durability Period of an engine with an intermediate rating would equate to 10 to 12 years . The Air Index is a calculated number describing the relative level of emissions for a specific engine family . The lower the Air Index , the cleaner the engine . This information is displayed in graphical form on the emissions label . 2 273v29,35 - page 2 ( Black ) cy : Screen angle and frequen 45.0000 , 150.0000

274273 BEFORE OPERATING ENGINE • Read entire Operating & Maintenance Instructions AND the instructions for the equipment this engine powers . * • Failure to follow instructions could result in serious injury or death . THE OPERATING & MAINTENANCE INSTRUCTIONS CONTAIN SAFETY INFORMATION TO • Make you aware of hazards associated with engines • Inform you of the risk of injury associated with those hazards , and • Tell you how to avoid or reduce the risk of injury . The safety alert symbol ( ) is used to identify safety HAZARD SYMBOLS AND MEANINGS information about hazards that can result in personal injury . A signal word ( DANGER , WARNING , or CAUTION ) is used with the alert symbol to indicate the likelihood and the Fire potential severity of injury . In addition , a hazard symbol Moving Parts may be used to represent the type of hazard . DANGER indicates a hazard which , if not avoided , will result in death or serious injury . Shock Explosion WARNING indicates a hazard which , if not avoided , could result in death or serious injury . Hot Surface Toxic Fumes CAUTION indicates a hazard which , if not avoided , might result in minor or moderate injury . CAUTION , when used without the alert symbol , Kickback indicates a situation that could result in damage to the engine . WARNING The engine exhaust from this prod - uct contains chemicals known to the State of California to cause cancer , birth defects , or other reproductive harm . * Briggs & Stratton does not necessarily know what equipment this engine will power . For that reason , you should carefully read and understand the operating instructions for the equipment on which your engine is placed . 3 273v29,35 - page 3 ( Black ) cy : Screen angle and frequen 45.0000 , 150.0000

SAFETY WARNING WARNING Unintentional sparking can result in fire or electric Gasoline and its vapors are extremely flammable shock . and explosive . Unintentional start - up can result in entanglement , Fire or explosion can cause severe burns or death . traumatic amputation , or laceration . WHEN ADDING FUEL • Turn engine OFF and let engine cool at least 2 BEFORE PERFORMING ADJUSTMENTS OR minutes before removing gas cap . REPAIRS • Fill fuel tank outdoors or in well - ventilated area . • Disconnect spark plug wire and keep it away from • Do not overfill fuel tank . Fill tank to approximately spark plug . 1 - 1 / 2 inches below top of neck to allow for fuel • Disconnect battery at negative terminal ( only expansion . engines with electric start ) . • Keep gasoline away from sparks , open flames , pilot lights , heat , and other ignition sources . WHEN TESTING FOR SPARK • Check fuel lines , tank , cap , and fittings frequently • Use approved spark plug tester . for cracks or leaks . Replace if necessary . • Do not check for spark with spark plug removed . WHEN STARTING ENGINE • Make sure spark plug , muffler , fuel cap and air cleaner are in place . • Do not crank engine with spark plug removed . WARNING • If fuel spills , wait until it evaporates before starting engine . • If engine floods , set choke to OPEN / RUN position , place throttle in FAST and crank until engine starts . Starting engine creates sparking . WHEN OPERATING EQUIPMENT Sparking can ignite nearby flammable gases . • Do not tip engine or equipment at angle which causes gasoline to spill . Explosion and fire could result . • Do not choke carburetor to stop engine . • If there is natural or LP gas leakage in area , do not WHEN TRANSPORTING EQUIPMENT start engine . • Transport with fuel tank EMPTY or with fuel shut - off • Do not use pressurized starting fluids because valve OFF . vapors are flammable . WHEN STORING GASOLINE OR EQUIPMENT WITH FUEL IN TANK • Store away from furnaces , stoves , water heaters or other appliances that have pilot light or other ignition source because they can ignite gasoline vapors . 4 273v29,35 - page 4 ( Black ) cy : Screen angle and frequen 45.0000 , 150.0000

MAINTENANCE ENGINE AND ENGINE PARTS We recommend that you see an authorized Briggs & Stratton Service Dealer for all maintenance and service of the engine and engine parts . Use only genuine Briggs & Stratton parts . If you perform any maintenance on the engine , first disconnect the spark plug wires from the spark plugs , and disconnect the battery at the negative terminal ( electric WARNING starter engines only ) to prevent unintentional sparking . Unintentional sparking can result in fire or electric shock . Unintentional start - up can result in entanglement , traumatic amputation or laceration . Use only correct tools . • Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation . WARNING • Do not tamper with governor spring , links or other parts to increase engine speed . MUFFLER AIR COOLING SYSTEM Replacement parts for the Debris may clog the engine’s air cooling system .
