Fire or explosion could result inburns or death.Fuel Storage• Because pilot lights or other ignition sources can cause explosions, keep fuel orequipment away from furnaces, stoves, water heaters or other appliances thathave pilot lights.NOTE:Some models have a fuel tank for vertical storage that will let the engine tilt formaintenance or storage (C, Figure 18). Do not keep in vertical position with the fuel tankfilled above the bottom of the fuel level indicator (D), if equipped. For more instructions,refer to the equipment manual.Keep the engine level (normal operating position). Fill the fuel tank (A, Figure 19) withfuel. For fuel expansion, do fill above the fuel tank neck (B).Fuel can become stale when kept in a storage container for more than 30 days.Theuse of an alcohol-free fuel stabilizer and ethanol treatment in the fuel storage containeris recommended. This keeps fuel fresh and decreases fuel-related problems orcontamination in the fuel system.When you fill the fuel container with fuel, add an alcohol-free fuel stabilizer as specifiedby the manufacturer’s instructions. If gasoline in the engine has not been treated with afuel stabilizer, it must be drained into an approved container. Operate the engine until itis out of fuel. Engine Oil While the engine is still warm, change the engine oil. Refer to Change the Engine Oilsection.

Torque values arederived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPMfor all others; horsepower values are derived at 3600 RPM. The gross power curvescan be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken withexhaust and air cleaner installed whereas gross power values are collected withoutthese attachments. Actual gross engine power will be higher than net engine power andis affected by, among other things, ambient operating conditions and engine-to-enginevariability. Given the wide array of products on which engines are placed, the gasolineengine may not develop the rated gross power when used in a given piece of powerequipment. This difference is due to a variety of factors including, but not limited to, thevariety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuelpump, etc.), application limitations, ambient operating conditions (temperature, humidity,altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations,Briggs & Stratton may substitute an engine of higher rated power for this engine. Warranty Briggs & Stratton

Look For Relevant Emissions Durability Period and Air Index Information On Your Small Off-Road Engine Emissions Label Engines that are certified to meet the California Air Resources Board (CARB) small off- road Emissions Standard must display information regarding the Emissions Durability Period and the Air Index. Briggs & Stratton makes this information available to the consumer on our emissions labels. The engine emissions label will indicate certification information. 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 Operator’s Manual. The following categories are used: Moderate: Engines at or less than 80 cc displacement are certified to be emissions compliant for 50 hours of actual engine running time. Engines greater than 80 cc displacement are certified to be emissions compliant for 125 hours of actual engine running time. Intermediate: Engines at or less than 80 cc displacement are certified to be emissions compliant for 125 hours of actual engine running time. Engines greater than 80 cc displacement are certified to be emissions compliant for 250 hours of actual engine running time. Extended: Engines at or less than 80 cc displacement are certified to be emissions compliant for 300 hours of actual engine running time. Engines greater than 80 cc displacement are certified to be emissions 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. Briggs & Stratton engines are certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emissions requirements.
