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 2 269v19,28 - page 2 ( 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 269v19,28 - 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 wire from the spark plug , 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 . CLEANING DEBRIS MUFFLER CAUTION : Do not use water to clean engine parts .
