These numbers are located on your engine (see the Features and Controls page). Date of purchase: Engine model: Model: MM/DD/YYYY Type: Code: 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 ). 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, riggs & Stratton may substitute an engine of higher rated power for this Series engine. Operator Safety Fire Fast Choke Hazardous Chemical SAFETY AND CONTROL SYMOLS Moving Parts Stop On Off Read Manual Oil Explosion Fuel Shutoff Hot Surface Toxic Fumes Shock Kickback Frostbite Slow Fuel Wear Eye Protection The safety alert symbol is used to identify safety information about hazards that can result in personal injury. A signal word (DANGER,, or CAUTION) is used with the alert symbol to indicate the likelihood and the potential severity of injury. In addition, a hazard symbol may be used to represent the type of hazard. DANGER indicates a hazard which, if not avoided, will result in death or serious injury. indicates a hazard which, if not avoided, could result in death or serious injury. The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. riggs & Stratton does not approve or authorize the use of these engines on 3-wheel All Terrain Vehicles (ATVs), motor bikes, fun/recreational go-karts, aircraft products, or vehicles intended for use in competitive events. Use of these engines in such applications could result in property damage, serious injury (including paralysis), or even death. CAUTION: This engine was shipped from riggs & Stratton without oil. efore you start the engine, make sure you add oil according to the instructions in this manual. If you start the engine without oil, it will be damaged beyond repair and will not be covered under warranty. Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. When Adding Fuel Turn engine off and let engine cool at least 2 minutes before removing the fuel cap. Fill fuel tank outdoors or in well-ventilated area. Do not overfill fuel tank. Fill tank to approximately 1.5 inches (38 mm) below top of neck to allow for fuel expansion. Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources. Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary If fuel spills, wait until it evaporates before starting engine. When Starting Engine Ensure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in place and secured. Do not crank engine with spark plug removed. If engine floods, set choke (if equipped) to OPEN/RUN position, move throttle (if equipped) to FAST position and crank until engine starts. When Operating Equipment Do not tip engine or equipment at angle which causes gasoline to spill. Do not choke the carburetor to stop engine. Never start or run the engine with the air cleaner assembly (if equipped) or the air filter (if equipped) removed. When Changing Oil If you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel can leak out and result in a fire or explosion. When Transporting Equipment Transport with fuel tank EMPTY or with fuel shut-off valve OFF. 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. Starting engine creates sparking. Sparking can ignite nearby flammable gases. Explosion and fire could result. If there is natural or LP gas leakage in area, do not start engine. Do not use pressurized starting fluids because vapors are flammable. CAUTION indicates a hazard which, if not avoided, might result in minor or moderate injury. CAUTION, when used without the alert symbol, indicates a situation that could result in damage to the product. Engines give off carbon monoxide, an odorless, colorless, poison gas. reathing carbon monoxide can cause nausea, fainting or death. Start and run engine outdoors. Do not start or run engine in enclosed area, even if doors or windows are open. 4 RIGGSandSTRATTON.COM Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. roken bones, fractures, bruises or sprains could result. When starting engine, pull the starter cord slowly until resistance is felt and then pull rapidly to avoid kickback. Remove all external equipment/engine loads before starting engine. Direct-coupled equipment components such as, but not limited to, blades, impellers, pulleys, sprockets, etc., must be securely attached. Rotating parts can contact or entangle hands, feet, hair, clothing, or accessories. Traumatic amputation or severe laceration can result. Operate equipment with guards in place. Keep hands and feet away from rotating parts. Tie up long hair and remove jewelry. Do not wear loose-fitting clothing, dangling drawstrings or items that could become caught. Unintentional sparking can result in fire or electric shock. Unintentional start-up can result in entanglement, traumatic amputation, or laceration. Fire hazard efore performing adjustments or repairs: Disconnect the spark plug wire and keep it away from the spark plug. Disconnect battery at negative terminal (only engines with electric start.) Use only correct tools. Do not tamper with governor spring, links or other parts to increase engine speed. Replacement parts must be the same and installed in the same position as the original parts. Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation. When testing for spark: Use approved spark plug tester. Do not check for spark with spark plug removed. Running engines produce heat. Engine parts, especially muffler, become extremely hot. Severe thermal burns can occur on contact. Combustible debris, such as leaves, grass, brush, etc. can catch fire. Allow muffler, engine cylinder and fins to cool before touching. Remove accumulated debris from muffler area and cylinder area. Install and maintain in working order a spark arrester before using equipment on forest-covered, grass-covered, brush-covered unimproved land. The state of California requires this (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal land. en 5 Features and Controls Compare the illustration 1 with your engine to familiarize yourself with the location of various features and controls. A.

Fuel Filter (optional) Operation Oil capacity (see the Specifications section) Oil Recommendations We recommend the use of riggs & Stratton Warranty Certified oils for best performance. Other high-quality detergent oils are acceptable if classified for service SF, SG, SH, SJ or higher. Do not use special additives. Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected. F C SAE 30 10W-30 * elow 40 F (4 C) the use of SAE 30 will result in hard starting. ** Above 80 F (27 C) the use of 10W-30 may cause increased oil consumption. Check oil level more frequently. How To Check/Add Oil - Figure 2 efore adding or checking the oil Place engine level. Clean the oil fill area of any debris. 1. Remove the dipstick (A) and wipe with a clean cloth (Figure 2). 2. Insert and tighten the dipstick. 3. Remove the dipstick and check the oil level. It should be at the FULL mark () onthe dipstick. 4. If low, add oil slowly into the engine oil fill (C). Do not overfill. After adding oil, wait one minute and then recheck the oil level. 5. Replace and tighten the dipstick. Synthetic 5W-30 5W-30 Oil Pressure If the oil pressure is too low, a pressure switch (if equipped) will either stop the engine or activate a warning device on the equipment. If this occurs, stop the engine and check the oil level with the dipstick. If the oil level is below the ADD mark, add oil until it reaches the FULL mark. Start the engine and check for proper pressure before continuing to operate. If the oil level is between the ADD and FULL marks, do not start the engine. Contact an Authorized riggs & Stratton Dealer to have the oil pressure problem corrected. 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) or up to 15% MTE (methyl tertiary butyl ether) is acceptable. CAUTION: Do not use unapproved gasolines, such as E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. This will damage the engine components and void the engine warranty. To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See Storage. All fuel is not the same. If starting or performance problems occur, change fuel providers or change brands. This engine is certified to operate on gasoline. The emissions control system for this engine is EM (Engine Modifications). High Altitude At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON) gasoline is acceptable. To remain emissions compliant, high altitude adjustment is required. Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions. See a riggs & Stratton Authorized Dealer for high altitude adjustment information. Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude kit is not recommended. How To Add Fuel - Figure 3 Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. When Adding Fuel Turn engine off and let engine cool at least 2 minutes before removing the fuel cap. Fill fuel tank outdoors or in well-ventilated area. Do not overfill fuel tank. Fill tank to approximately 1.5 inches (38 mm) below top of neck to allow for fuel expansion. Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources. Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary. If fuel spills, wait until it evaporates before starting engine. 1. Clean the fuel cap area of dirt and debris. Remove the fuel cap (A, Figure 3). 2. Fill the fuel tank () with gasoline. To allow for expansion of the gasoline, do not fill above the bottom of the fuel tank neck (C). 3. Reinstall the fuel cap.
