Use of these engines in such applications could result in property damage, serious injury (including paralysis), or even death.

WARNING

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 gas cap.
• Fill fuel tank outdoors or in well-ventilated area.
• On GASOLINE operated engines do not overfill fuel tank.
• 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.

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 GASOLINE engine floods, set choke to OPEN/RUN position, place throttle in FAST and crank until engine starts.

WHEN OPERATING EQUIPMENT WITH GASOLINE ENGINE

• Do not tip engine or equipment at angle which causes gasoline to spill.
• Do not choke carburetor to stop engine.

WHEN TRANSPORTING EQUIPMENT

Gasoline Engine: Transport with fuel tank EMPTY or with fuel shut-off valve OFF.
- LIQUID PETROLEUM GAS (LPG) / NATURAL GAS (NG) ENGINE: Transport with fuel cylinder EMPTY and valve closed or tank disconnected.

WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK OR IN FUEL CYLINDER

• Store away from furnaces, stoves, water heaters or other appliances that have pilot light or other ignition source because they can ignite gasoline vapors.

WARNING

Gaseous fuels are extremely flammable and readily form explosive air-vapor mixtures at ambient temperatures.

IF YOU SMELL GAS:

• DO NOT start the engine.
• DO NOT actuate any electrical switches.
• DO NOT use the phone in the vicinity.
  Evacuate the area.
• Contact the gas supplier or fire department.

REMEMBER:

• LPG vapor is heavier than air and trends to collect in low areas. NG vapor is lighter than air and tends to collect in high areas. Both may travel to remote locations.
• Keep all flames, sparks, pilot lights, and other ignition sources away from the area where the engine is operated or repaired.
• DO NOT smoke when operating or repairing the engine.
• DO NOT store gasoline or other flammable vapors or liquids in the vicinity of the engine.
  BEFORE doing any service work to the engine, shut off the gas supply.
• After initial installation or servicing, check for gas leaks. DO NOT use an open flame. Apply very soapy water or leak test solution with a brush and look for bubbles.
• Keep the equipment and the area surrounding the engine free of debris.
• Install the fuel system according to applicable fuel/gas codes.

WARNING

Engines give off carbon monoxide, an odorless, colorless, poison gas.

Breathing 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.

WARNING

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.

WARNING

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.

WARNING

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.

• When starting engine, pull cord slowly until resistance is felt, then pull rapidly.
• Remove all external equipment/engine loads before starting engine.
• Direct coupled equipment components such as, but not limited to, blades, impellors, pulleys, sprockets, etc., must be securely attached.

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.

• 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. 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.

WARNING

Wear eye protection when doing repair work.

Frostbite can result from skin/eye contact with leaking LP liquid.

• Installation, adjustment and repair work should be done by a qualified technician.
• Flexible supply lines should be checked regularly to make sure they are in good condition. Replace damaged or leaking components.

WARNING

Unintentional sparking can result in fire or electric shock. Unintentional start-up can result in entanglement, traumatic amputation, or laceration.

BEFORE PERFORMING ADJUSTMENTS OR REPAIRS

• Disconnect spark plug wires and keep them away from spark plugs.

WHEN TESTING FOR SPARK

• Use approved spark plug tester.
• Do not check for spark with spark plugs removed.

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^ and higher (5°C and higher) is good for all purpose use above 40^ , use below 40^ will cause hard starting.

10W-30 0 to 100^ (-18 to 38^)

is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80^ (27^) or higher.

Check oil level frequently at higher temperatures.

Synthetic 5W-30 -20 to 120^ (-30 to 40^)

provides the best protection at all temperatures as well as improved starting with less oil consumption.

5W-30 40^ and below (5°C and below)

is recommended for winter use, and works best in cold conditions.

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

1. For first use or when performing oil change, add 1 liter (32 ounces).
2. Start and run engine at idle for 30 seconds. Shut engine off and wait 30 seconds.
3. Then add more oil slowly to bring level to FULL mark 4 on dipstick. Check for oil leaks.
4. Tighten dipstick firmly before starting engine.

CHECKING OIL

1. Place engine on level surface and clean around oil fill ①.
2. Remove dipstick ②, wipe with clean cloth. Insert dipstick firmly ③, then remove and check oil level.
3. Oil should be at FULL mark 4. If oil is required, add oil slowly.
4. Tighten dipstick firmly before starting engine.

OIL PRESSURE

If engine runs low on oil, an oil pressure switch (if engine is equipped) will either activate a warning device or stop the engine. (Read the operating instructions supplied by the equipment manufacturer to determine which way your engine is equipped.) See Maintenance for further information.

FUEL RECOMMENDATIONS

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 (methyl tertiary butyl ether), is acceptable.
• Use of any gasoline other than those approved above will 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. If 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. Excessive 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.

HIGH ALTITUDE USE

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 overfill.

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 ^3 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.

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.

1. Change oil. See Oil service.
2. Remove spark plug and pour about 30ml (1 oz) of engine oil into cylinder. Replace spark plug and crank slowly to distribute oil.
3. Clean chaff and debris from cylinder and cylinder head fins, under finger guard and behind muffler.
4. When removing the unit from storage, only use fresh gasoline. Perform operation checks, see maintenance schedule, before starting engine.

B&S recommends that you retain all your receipts covering maintenance on your small off-road engine, but B&S cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the small off-road engine owner, you should however be aware that B&S may deny your warranty coverage if your small off-road engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.

You are responsible for presenting your small offroad engine to an Authorized B&S Service Dealer as soon as a problem exists. The undisputed warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you should contact a B&S Service Representative at 1-414-259-5262.

The emissions warranty is a defects warranty. Defects are judged on normal engine performance. The warranty is not related to an in-use emissions test.

3. No Charge

Repair or replacement of any Warranted Part will be performed at no charge to the owner, including diagnostic labor which leads to the determination that a Warranted Part is defective, if the diagnostic work is performed at an Authorized B&S Service Dealer. For emissions warranty service contact your nearest Authorized B&S Service Dealer as listed in the "Yellow Pages" under "Engines, Gasoline," "Gasoline Engines," "Lawn Mowers," or similar category.

4. Claims and Coverage Exclusions

Warranty claims shall be filed in accordance with the provisions of the B&S Engine Warranty Policy. Warranty coverage shall be excluded for failures of Warranted Parts which are not original B&S parts or because of abuse, neglect or improper maintenance as set forth in the B&S Engine Warranty Policy. B&S is not liable to cover failures of Warranted Parts caused by the use of add-on, non-original, or modified parts.

5. Maintenance

Any Warranted Part which is not scheduled for replacement as required maintenance or which is scheduled only for regular inspection to the effect of "repair or replace as necessary" shall be warranted as to defects for the warranty period. Any Warranted Part which is scheduled for replacement as required maintenance shall be warranted as to defects only for the period of time up to the first scheduled replacement for that part. Any replacement part that is equivalent in performance and durability may be used in the performance of any maintenance or repairs. The owner is responsible for the performance of all required maintenance, as defined in the B&S Operating and Maintenance Instructions.

6. Consequential Coverage

Coverage hereunder shall extend to the failure of any engine components caused by the failure of any Warranted Part still under warranty.

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 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. Therefore, the Emissions Durability Period of an engine with an intermediate rating would equate to 10 to 12 years.

Certain Briggs & Stratton engines will be certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 emission standards. For Phase 2 certified engines, 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 emission requirements.

For engines less than 225 cc displacement.

Category C = 125 hours

Category B = 250 hours

Category A = 500 hours

For engines of 225 cc or more displacement.

Category C = 250 hours

Category B = 500 hours

Category A = 1000 hours.

ABOUT YOUR ENGINE WARRANTY

Briggs & Stratton welcomes warranty repair and apologizes to you for being inconvenienceed. 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.

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:

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. 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 Fuel Stabilizer, Part No. 5041.)
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. OIL GARD may not shut down running engine. Engine damage may occur if oil level is not properly maintained.
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.

1. Parts damaged by over-speeding, 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.
2. 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, over-speeding or other abuse in operation.
3. 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.
4. Routine tune-up or adjustment of the engine.
5. Engine or engine component failure, i.e., combustion chamber, valves, valve seats, valve guides, or burned starter motor windings, caused by the use of alternate fuels such as, liquified petroleum, natural gas, altered gasolines, etc.

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 PagesTM" of your telephone directory under "Engines, Gasoline" or "Gasoline Engines," "Lawn Mowers," or similar category.
