OIL RECOMMENDATIONS Use a high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. Do not use special additives. SAE 30 40 °F and higher (5 °C and higher) is good for all purpose use above 40°F, use below 40°F will cause hard starting. 10W-30 0 to 100 °F (-18 to 38°C) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80°F (27°C) or higher. ‘x Check oil level frequently at higher temperatures. Synthetic 5W-30 -20 to 120 °F (-30 to 40 °C) provides the best protection at all temperatures as well as improved starting with less oil consumption. 5W-30 40 °F and below (5 °C and below) is recommended for winter use, and works best in cold conditions. 104F “ “0 C #6 J

OIL CAPACITY Approximately 1-1/2 quarts (48 ounces or 1.6 liters) when changing oil and filter. (Oil capacity will be greater if engine is equipped with remote oil filter.) CAUTION: Engine is shipped from Briggs & Stratton without oil. Before starting engine, fill to FULL mark on dipstick with oil. Do not over fill. ADDING OIL - SEE FIGURE (2)

GASOLINE POWERED ENGINES

This engine is certified to operate on gasoline. The emission control system for this engine is EM (Engine Modifications). Always use gasoline that meets these requirements and follow these guidelines: + Clean, fresh unleaded gasoline. + A minimum of 87 octane/87 AKI (91 RON). If operating at high altitude, see below. + Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methy/ teriary butyl ether), is acceptable. + Use of any gasoline other than those approved above wil| void the engine warranty. In some local areas fuel pumps may be marked if the gasoline contains alcohols or ethers. If you are unsure about the gasoline you purchase check with your fuel provider. + Do not modify the engine fuel system or carburetor to run on alternative fuels. + Never mix oil with gasoline. All gasoline is not the same. lf you experience starting or performance problems after new gasoline has been used in your engine, switch to a different fuel provider or change fuel brands. CAUTION: Some fuels, called oxygenated or reformulated fuels, are fuels blended with alcohols or ethers. Éxcessive amounts of these blends can damage the fuel system or cause performance problems. If any undesirable operating symptoms occur, use gasoline with a lower percentage of alcohol or ether. FUEL STABILIZER To protect the fuel system from gum formation, mix in a fuel preservative when adding fuel. Briggs & Stratton recommends using FRESH START " fuel stabilizer, available as a liquid additive, concentrated liquid cartridge or granular additive.

At higher altitudes (over 5,000 feet), 85 octane/85 AKI (89 RON) gasoline can be used. Operation at high altitude may require a high-altitude carburetor jet kit to improve performance and decrease fuel consumption. See an Authorized Briggs & Stratton dealer for more information. ADDING GASOLINE Clean around fuel fill before removing cap. Remove cap. Fill tank to approximately 1-1/2 inches below top of neck to allow for fuel expansion. Be careful not to overfil. LIQUID PROPANE GAS (LPG)

NATURAL GAS (NG) POWERED ENGINES

+ Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems. + In engines set up to run on LPG, commercial grade HD5 LPG is recommended. Recommended fuel composition is fuel with a minimum fuel energy of 2500 BTU's/ft$ with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%. + LPG or NG engines are certified to operate on liquid propane or natural gas. ADDING FUEL Read the operating instructions supplied by the equipment manufacturer for information on refueling LPG or NG engine. PINS LPG/NG Engines: The equipment on which this engine is mounted is equipped with an automatic safety gas “fuel lock-off” valve. DO NOT operate the equipment if the “fuel lock-off” valve is missing or inoperative, explosion or fire could occur.

Refer to the equipment operator manual for safe allowable operating limits on slopes. Technical Information Engine Power Rating Information The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual “on-site” or net power). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, 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 Series engine. STORAGE Engines stored over 30 days need to be protected or drained of fuel to prevent gum from forming in fuel system or on essential carburetor parts. For engine protection, we recommend use of Briggs & Stratton Fuel Stabilizer available from an Authorized Briggs & Stratton Service Dealer. Mix stabilizer with fuel in fuel tank or storage container. Run engine for a short time to circulate stabilizer through carburetor. Engine and fuel can be stored up to 24 months. Note: If stabilizer is not used or if engine is operating on gasoline containing alcohol, e.g. gasohol, remove all fuel from tank and run engine until it stops from lack of fuel. p. 0

Look For Relevant Emissions Durability Period and Aïr Index Information On Your Engine Emissions Label Engines that are certified to meet the Califomia 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 engine emission 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 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.
