In the USA and Canada our 24 hour hotline is 1-800-233-3723 Briggs & Stratton Corporation Milwaukee, Wisconsin 53201 www.briggsandstratton.com Copyright 1999 by Briggs & Stratton Corporation FORM NO. 274273-10/99 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) Screen angle and frequency: 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.

Unintentional sparking can result in fire or electric shock. Fire or explosion can cause severe burns or death. Unintentional start-up can result in entanglement, traumatic amputation, or laceration. WHEN ADDING FUEL • Turn engine OFF and let engine cool at least 2 minutes before removing gas cap. • Fill fuel tank outdoors or in well-ventilated area. • Do not overfill fuel tank. Fill tank to approximately 1-1/2 inches 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. BEFORE PERFORMING ADJUSTMENTS OR REPAIRS • Disconnect spark plug wire and keep it away from spark plug. • Disconnect battery at negative terminal (only engines with electric start). WHEN TESTING FOR SPARK • Use approved spark plug tester. • 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. • 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. WARNING Starting engine creates sparking. WHEN OPERATING EQUIPMENT • Do not tip engine or equipment at angle which causes gasoline to spill. • Do not choke carburetor to stop engine. 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. 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. 4 273v29,35 - page 4 (Black) Screen angle and frequency: 45.0000, 150.0000 SAFETY WARNING WARNING Engines give off carbon monoxide, an odorless, colorless, poison gas. Rotating parts can contact or entangle hands, feet, hair, clothing, or accessories. Breathing carbon monoxide can cause nausea, fainting or death. Traumatic amputation or severe laceration can result. • Start and run engine outdoors. • Do not start or run engine in enclosed area, even if doors or windows are open. • 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. WARNING WARNING 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. Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises or sprains could result. • Allow muffler, engine cylinder and fins to cool before touching. • Remove accumulated combustibles 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.

In the USA and Canada, a 24 hour hot line, 1-800-233-3723, has a menu of pre-recorded messages offering you engine maintenance information. 17 About your engine warranty: (see next page for statement of LIMITED WARRANTY). Briggs & Stratton welcomes warranty repair and apologizes to you for being inconvenienced. Any Authorized Service Dealer may perform warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example, warranty would not apply if engine damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation. Similarly, warranty is void if the serial number of the engine has been removed or the engine has been altered or modified. If a customer differs with the decision of the Service Dealer, an investigation will be made to determine whether the warranty applies. Ask the Service Dealer to submit all supporting facts to his Distributor or the Factory for review. If the Distributor or the Factory decides that the claim is justified, the customer will be fully reimbursed for those items that are defective. To avoid misunderstanding which might occur between the customer and the Dealer, listed below are some of the causes of engine failure that the warranty does not cover. 4. Parts which are scored or broken because an engine was operated with insufficient or contaminated lubricating oil, or an incorrect grade of lubricating oil (check oil level daily or after every 8 hours of operation. Refill when necessary and change at recommended intervals.) OIL GARD may not shut down running engine. Engine damage may occur if oil level is not properly maintained. Read Operating & Maintenance Instructions. 5. Repair or adjustment of associated parts or assemblies such as clutches, transmissions, remote controls, etc., which are not manufactured by Briggs & Stratton. 6. Damage or wear to parts caused by dirt, which entered the engine because of improper air cleaner maintenance, re-assembly, or use of a non-original air cleaner element or cartridge. (At recommended intervals, clean and re-oil the Oil-Foam element or the foam pre-cleaner, and replace the cartridge.) Read Operating & Maintenance Instructions. 7. Parts damaged by overspeeding, or overheating caused by grass, debris, or dirt, which plugs or clogs the cooling fins, or flywheel area, or damage caused by operating the engine in a confined area without sufficient ventilation. (Clean fins on the cylinder, cylinder head and flywheel at recommended intervals.) Read Operating & Maintenance Instructions. Normal wear: Engines, like all mechanical devices, need periodic parts service and replacement to perform well. Warranty will not cover repair when normal use has exhausted the life of a part or an engine. Improper maintenance: 8. Engine or equipment parts broken by excessive vibration caused by a loose engine mounting, loose cutter blades, unbalanced blades or loose or unbalanced impellers, improper attachment of equipment to engine crankshaft, overspeeding or other abuse in operation. The life of an engine depends upon the conditions under which it operates, and the care it receives. Some applications, such as tillers, pumps and rotary mowers, are very often used in dusty or dirty conditions, which can cause what appears to be premature wear. Such wear, when caused by dirt, dust, spark plug cleaning grit, or other abrasive material that has entered the engine because of improper maintenance, is not covered by warranty. 9. A bent or broken crankshaft, caused by striking a solid object with the cutter blade of a rotary lawn mower, or excessive v-belt tightness. 10. Routine tune-up or adjustment of the engine. This warranty covers engine related defective material and/or workmanship only, and not replacement or refund of the equipment to which the engine may be mounted. Nor does the warranty extend to repairs required because of: 1. PROBLEMS CAUSED BY PARTS THAT ARE NOT ORIGINAL BRIGGS & STRATTON PARTS. 2. Equipment controls or installations that prevent starting, cause unsatisfactory engine performance, or shorten engine life. (Contact equipment manufacturer.) 3. Leaking carburetors, clogged fuel pipes, sticking valves, or other damage, caused by using contaminated or stale fuel. (Use clean, fresh, lead-free gasoline and Briggs & Stratton gasoline stabilizer, Part No. 5041.) Warranty is available only through service dealers which have been authorized by Briggs & Stratton Corporation. Your nearest Authorized Service Dealer is listed in the “Yellow Pages” of your telephone directory under “Engines, Gasoline” or “Gasoline Engines,” “Lawn Mowers,” or similar category.
