8OilCapacityEngine without oil filter holds approximately 1-7/8 quarts(60 ounces; 1.8 liter).

Engine equipped with oil filter holds approximately2 quarts (64 ounces; 1.9 liters).

RecommendationsS Use a high quality detergent motor oil, such as

Briggs & Stratton 30W, Part Number 100005 (20 oz)or 100028 (48 oz).

S DO NOT use special additives.

S Choose a viscosity according to the table shown.

Note: Synthetic oil meeting ILSAC GF-2,API certification mark and API service sym-bol (shown at left) with SJ/CF ENERGYCONSERVING or higher, is an acceptableoil at all temperatures. Use of synthetic oildoes not alter required oil changeintervals.

* Air cooled engines run hotter thanautomotive engines. The use ofnon-synthetic multi-viscosity oils (5W-30,10W-30, etc.) in temperatures above 40 F(4 C) will result in higher than normal oilconsumption. When using a multi-viscosityoil, check oil level more frequently.

** SAE 30 oil, if used below 40 F (4 C), willresult in hard starting and possible enginebore damage due to inadequatelubrication.

Technical InformationPower Ratings: The power ratings for an individualengine model are initially developed by starting withSAE (Society of Automotive Engineers) code J1940(Small Engine Power & Torque Rating Procedure)(Revision 2002-05). Given both the wide array ofproducts on which our engines are placed, and thevariety of environmental issues applicable to operatingthe equipment, it may be that the engine you havepurchased will not develop the rated horsepower whenused in a piece of power equipment (actual on-sitepower). This difference is due to a variety of factorsincluding, but not limited to, the following: differences inaltitude, temperature, barometric pressure, humidity,fuel, engine lubrication, maximum governed enginespeed, individual engine to engine variability, design ofthe particular piece of power equipment, the manner inwhich the engine is operated, engine run-in to reducefriction and clean out of combustion chambers,adjustments to the valves and carburetor, and otherfactors. The power ratings may also be adjusted basedon comparisons to other similar engines utilized insimilar applications, and will therefore not necessarilymatch the values derived using the foregoing codes.

Emission InformationEngines that are certified to meet the California AirResources Board (CARB) Tier 2 Emission Standardsmust display information regarding the EmissionsDurability Period and the Air Index. Briggs & Strattonmakes this information available to the consumer on ouremission labels. The engine emission label will indicatecertification information.The Emissions Durability Period describes thenumber of hours of actual running time for which theengine is certified to be emissions compliant, assumingproper maintenance in accordance with the Operating &Maintenance Instructions. The following categories areused:Moderate:Engine is certified to be emission compliant for 125hours of actual engine running time.Intermediate:Engine is certified to be emission compliant for 250hours of actual engine running time.Extended:Engine is certified to be emission compliant for 500hours of actual engine running time. For example, atypical walk-behind lawn mower is used 20 to 25 hoursper year. Therefore, the Emissions Durability Periodof an engine with an intermediate rating would equateto 10 to 12 years.Certain Briggs & Stratton engines will be certified tomeet the United States Environmental ProtectionAgency (USEPA) Phase 2 emission standards.

Briggs & Stratton welcomes warranty repair andapologizes to you for being inconvenienced. AnyAuthorized Service Dealer may perform warrantyrepairs. Most warranty repairs are handled routinely,but sometimes requests for warranty service may notbe appropriate. For example, warranty would not applyif engine damage occurred because of misuse, lack ofroutine maintenance, shipping, handling, warehousingor improper installation. Similarly, warranty is void if theserial number of the engine has been removed or theengine has been altered or modified.If a customer differs with the decision of the ServiceDealer, an investigation will be made to determinewhether the warranty applies. Ask the Service Dealerto submit all supporting facts to his Distributor or theFactory for review. If the Distributor or the Factorydecides that the claim is justified, the customer will befully reimbursed for those items that are defective. Toavoid misunderstanding which might occur betweenthe customer and the Dealer, listed below are some ofthe causes of engine failure that the warranty does notcover.Normal wear:Engines, like all mechanical devices, need periodicparts service and replacement to perform well.Warranty will not cover repair when normal use hasexhausted the life of a part or an engine.Improper maintenance:The life of an engine depends upon the conditionsunder which it operates, and the care it receives.Some applications, such as tillers, pumps and rotarymowers, are very often used in dusty or dirtyconditions, which can cause what appears to bepremature wear. Such wear, when caused by dirt, dust,spark plug cleaning grit, or other abrasive material thathas entered the engine because of impropermaintenance, is not covered by warranty.This warranty covers engine related defectivematerial and/or workmanship only, and notreplacement or refund of the equipment to whichthe engine may be mounted. Nor does the warrantyextend 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 equipmentmanufacturer.)

3. Leaking carburetors, clogged fuel pipes, stickingvalves, or other damage, caused by usingcontaminated or stale fuel. (Use clean, fresh,lead-free gasoline and Briggs & Stratton FuelStabilizer, Part No. 5041.)

4. Parts which are scored or broken because anengine was operated with insufficient orcontaminated lubricating oil, or an incorrect gradeof lubricating oil (check oil level daily or after every8 hours of operation.

Read Operating & MaintenanceInstructions.

5. Repair or adjustment of associated parts orassemblies such as clutches, transmissions,remote controls, etc., which are not manufacturedby Briggs & Stratton.

6. Damage or wear to parts caused by dirt, whichentered the engine because of improper aircleaner maintenance, re-assembly, or use of anon-original air cleaner element or cartridge. (Atrecommended intervals, clean and re-oil theOil-Foam element or the foam pre-cleaner, andreplace the cartridge.) Read Operating &Maintenance Instructions.

7. Parts damaged by over-speeding, or overheatingcaused by grass, debris, or dirt, which plugs orclogs the cooling fins, or flywheel area, or damagecaused by operating the engine in a confined areawithout sufficient ventilation. (Clean fins on thecylinder, cylinder head and flywheel atrecommended intervals.) Read Operating &Maintenance Instructions.

8. Engine or equipment parts broken by excessivevibration caused by a loose engine mounting,loose cutter blades, unbalanced blades or loose orunbalanced impellers, improper attachment ofequipment to engine crankshaft, over-speeding orother abuse in operation.

9. A bent or broken crankshaft, caused by striking asolid object with the cutter blade of a rotary lawnmower, or excessive v-belt tightness.

10. Routine tune-up or adjustment of the engine.11. Engine or engine component failure, i.e.,
