OperationOil CapacityModel 120000 and 150000 series engines:20 ounces (0.6 liter).

Model 200000 and 210000 series engines:28 ounces (0.8 liter).

Oil Recommendation

• Do not use special additives.• Choose a viscosity from the following chart.

SAE 30 40° F and higher (5° C and higher)is good for all purpose use above 40°F, use below40°F will cause hard starting.

10W-30 0 to 100° F (--18 to 38° C)is better for varying temperature conditions. Thisgrade of oil improves cold weather starting, but mayincrease oil consumption at 80°F (27°C) or higher.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 aswell 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 incold conditions.

If this engine is equipped with a gear reductionunit, the gear reduction case must be filled with oilprior to operating the engine. See “How To ChangeThe Gear Reduction Oil” in the MaintenanceSection.

CAUTION

Fuel Recommendations

This engine is certified to operate on gasoline. Theemissions control system for this engine is EM(Engine Modifications).

Gasoline must meet these requirements:

• Clean, fresh, unleaded gasoline.• A minimum of 87 octane/87 AKI (91 RON). Ifoperating at high altitude, see below.

• Gasoline with up to 10% ethanol (gasohol) or upto 15% MTBE (methyl tertiary butyl ether), isacceptable.

• Use of any gasoline not consistent with therequirements will void the engine warranty.

In some local areas, fuel pumps may be marked if thegasoline contains alcohols or ethers. If you are unsureabout the gasoline you purchase, check with your fuelprovider.

• Do not modify the engine fuel system orcarburetor to run on alternative fuels.

• Never mix oil with gasoline.

All gasoline is not the same. If you experience startingor performance problems after new gasoline has beenused in your engine, switch to a different fuel provideror change fuel brands.

Some fuels, called oxygenated or reformulated fuels,are fuels blended with alcohols or ethers. Excessiveamounts of these blends can damage the fuelsystem or cause performance problems. If anyundesirable operating symptoms occur, use gasolinewith a lower percentage of alcohol or ether.

CAUTION

Fuel Stabilizer

To protect the fuel system from gum formation, mix ina fuel preservative when adding fuel. Briggs &Stratton recommends using FRESH STARTt fuel

stabilizer, available as a liquid additive, concentratedliquid 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 highaltitude may require a high-altitude carburetor jet kit toimprove performance and decrease fuel consumption.See an Authorized Briggs & Stratton service dealer formore information.

Add Fuel (Figure 4)


• Turn engine off and let engine cool at least 2minutes before removing the gas cap.

• Fill fuel tank outdoors or in well-ventilated area.• Keep gasoline away from sparks, open flames,pilot lights, heat, and other ignition sources.


WARNING

1. Stop the engine. Before you remove gas cap (A),let the engine cool at least 2 minutes.

2. Remove the gas cap. Fill the fuel tank (B) toapproximately 1-1/2 inches below top of neck toallow for fuel expansion. Be careful, do not overfill.

Clean Air Cooling System (Figure 25)

Do not use water to clean the engine. Water couldcontaminate the fuel system. Use a brush or drycloth to clean the engine.

CAUTION

Running engines produce heat.Engine parts, especially muffler,become extremely hot.Severe thermal burns can occur oncontact.Combustible debris, such as leaves,grass, brush, etc. can catch fire.

• Allow muffler, engine cylinder and fins to coolbefore touching.

• Remove accumulated debris from muffler areaand cylinder area.

WARNING

This is an air cooled engine. Dirt or debris can restrictair flow and cause the engine to over heat, resulting inpoor performance and reduced engine life. Daily orbefore every use, check the engine for accumulateddirt or debris that may restrict air flow. Use a brush ordry cloth to remove debris from the finger guard (A).

Keep linkage, springs and controls (B) clean. Keepthe area around and behind the muffler (C) free of anycombustible debris.

Over time, debris can accumulate in the cylindercooling fins and cause the engine to overheat. Thisdebris cannot be observed without partial disassemblyof the engine. For this reason, have an authorizedBriggs & Stratton Service Dealer inspect and cleanthe air cooling system as recommended in the“Maintenance Chart”.

Storage (over 30 days)


When Storing Gasoline Or Equipment WithFuel In Tank

• Store away from furnaces, stoves, waterheaters or other appliances that have pilotlights or other ignition sources because theycan ignite gasoline vapors.

WARNING

Fuel System

Fuel can become stale when stored over 30 days.Stale fuel causes acid and gum deposits to form in thefuel system or on essential carburetor parts. Mix fuelstabilizer with the fuel in the tank or storage container.Run the engine for a short time to circulate stabilizerthrough the carburetor and engine. Engine and fuelcan then be stored up to 24 months.

If fuel stabilizer is used, you do not need to drain thegasoline prior to storage. If fuel stabilizer is not used,run the engine until it stops from lack of fuel.

If a FRESH STARTt fuel cap with a cartridge ofconcentrated slow drip stabilizer is used, there is noneed to drain the fuel for seasonal storage as long asthe cartridge contains stabilizer.

Engine oil

While the engine is still warm, change the engine oil.

Lubricate cylinder and piston

Remove the spark plug and pour approximately 1 oz(30 ml) of engine oil into the spark plug hole. Replacethe spark plug and slowly pull the starter rope todistribute the oil.

Clean engine

Clean engine of surface debris, chaff, or grass.

Storage Area

Store in a clean, dry area. Do not store in the samearea as a stove, furnace, water heater, or otherappliance that uses a pilot light or has a device thatcan create a spark.

General InformationThis is a single cylinder, overhead valve (OHV)air-cooled engine. It is a low emissions engine.

In the state of California, OHV Model 120000 and150000 engines are certified by the California AirResources Board to meet emissions standards for125 hours. OHV Model 200000 and 210000 enginesare certified by the California Air Resources Board tomeet emissions standards for 250 hours. Suchcertification does not grant the purchaser, owner oroperator of this engine any additional warranties withrespect to the performance or operational life of thisengine. This engine is warranted solely according tothe product and emissions warranties statedelsewhere in this manual.

Engine Power Rating Information

The gross power rating for individual gas enginemodels is labeled in accordance with SAE (Society ofAutomotive Engineers) code J1940 (Small Engine

Power & Torque Rating Procedure), and ratingperformance has been obtained and corrected inaccordance with SAE J1995 (Revision 2002-05).Torque values are derived at 3060 RPM; horsepowervalues are derived at 3600 RPM. Actual gross enginepower will be lower and is affected by, among otherthings, ambient operating conditions andengine-to-engine variability. Given both the wide arrayof products on which engines are placed and thevariety of environmental issues applicable tooperating the equipment, the gas engine will notdevelop the rated gross power when used in a givenpiece of power equipment (actual “on-site” or netpower). This difference is due to a variety of factorsincluding, but not limited to, accessories (air cleaner,exhaust, charging, cooling, carburetor, fuel pump,etc.), application limitations, ambient operatingconditions (temperature, humidity, altitude), andengine-to-engine variability. Due to manufacturing andcapacity limitations, Briggs & Stratton may substitutean engine of higher rated power for this Seriesengine.

ABOUT YOUR WARRANTY

Briggs & Stratton welcomes warranty repair and apologizes to you for beinginconvenienced. Any Authorized Service Dealer may perform warranty repairs.Most warranty repairs are handled routinely, but sometimes requests forwarranty service may not be appropriate. For example, warranty would notapply if engine damage occurred because of misuse, lack of routinemaintenance, shipping, handling, warehousing or improper installation.Similarly, warranty is void if the serial number of the engine has been removedor the engine has been altered or modified.If a customer differs with the decision of the Service Dealer, an investigation willbe made to determine whether the warranty applies. Ask the Service Dealer tosubmit all supporting facts to his Distributor or the Factory for review. If theDistributor or the Factory decides that the claim is justified, the customer will befully reimbursed for those items that are defective. To avoid misunderstandingwhich might occur between the customer and the Dealer, listed below are someof the causes of engine failure that the warranty does not cover.Normal wear:Engines, like all mechanical devices, need periodic parts service andreplacement to perform well. Warranty will not cover repair when normal usehas exhausted the life of a part or an engine.Improper maintenance:The life of an engine depends upon the conditions under which it operates, andthe care it receives. Some applications, such as tillers, pumps and rotarymowers, are very often used in dusty or dirty conditions, which can cause whatappears to be premature wear. Such wear, when caused by dirt, dust, sparkplug cleaning grit, or other abrasive material that has entered the enginebecause of improper maintenance, is not covered by warranty.This warranty covers engine related defective material and/orworkmanship only, and not replacement or refund of the equipment towhich the engine may be mounted. Nor does the warranty extend to repairsrequired 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. (Contactequipment manufacturer.)

3 Leaking carburetors, clogged fuel pipes, sticking valves, or other damage,caused by using contaminated or stale fuel. (Use clean, fresh, lead-freegasoline and Briggs & Stratton Fuel Stabilizer, Part No. 5041.)

4 Parts which are scored or broken because an engine was operated withinsufficient or contaminated lubricating oil, or an incorrect grade oflubricating oil (check oil level daily or after every 8 hours of operation. Refillwhen necessary and change at recommended intervals.) OIL GARD maynot shut down running engine. Engine damage may occur if oil level is notproperly 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 becauseof improper air cleaner maintenance, re-assembly, or use of a non-originalair cleaner element or cartridge. (At recommended intervals, clean andre-oil the Oil-Foam element or the foam pre-cleaner, and replace thecartridge.) Read Operating & Maintenance Instructions.

7 Parts damaged by over-speeding, or overheating caused by grass, debris,or dirt, which plugs or clogs the cooling fins, or flywheel area, or damagecaused by operating the engine in a confined area without sufficientventilation. (Clean fins on the cylinder, cylinder head and flywheel atrecommended intervals.) Read Operating & Maintenance Instructions.

8 Engine or equipment parts broken by excessive vibration caused by aloose engine mounting, loose cutter blades, unbalanced blades or loose orunbalanced impellers, improper attachment of equipment to enginecrankshaft, over-speeding or other abuse in operation.

9 A bent or broken crankshaft, caused by striking a solid object with thecutter blade of a rotary lawn mower, or excessive v-belt tightness.

10 Routine tune-up or adjustment of the engine.

11 Engine or engine component failure, i.e., combustion chamber, valves,valve seats, valve guides, or burned starter motor windings, caused by theuse of alternate fuels such as, liquified petroleum, natural gas, alteredgasolines, etc.

Warranty service is available only through service dealers which have beenauthorized by Briggs & Stratton Corporation.

Look For Relevant Emissions Durability Period andAir Index Information On Your Engine Emissions LabelEngines that are certified to meet the California Air Resources Board(CARB) Tier 2 Emissions Standard must display informationregarding the Emissions Durability Period and the Air Index. Briggs &Stratton makes this information available to the consumer on ouremissions labels. The engine emissions label will indicate certificationinformation.

The Emissions Durability Period describes the number of hours ofactual running time for which the engine is certified to be emissionscompliant, assuming proper maintenance in accordance with theOperating & Maintenance Instructions. The following categories areused:

Moderate:Engine is certified to be emissions compliant for 125 hours of actualengine running time.

Intermediate:Engine is certified to be emissions compliant for 250 hours of actualengine running time.

Extended:Engine is certified to be emissions compliant for 500 hours of actualengine running time. For example, a typical walk-behind lawn moweris used 20 to 25 hours per year. Therefore, the Emissions DurabilityPeriod of an engine with an intermediate rating would equate to 10to 12 years.

Certain Briggs & Stratton engines will be certified to meet the UnitedStates Environmental Protection Agency (USEPA) Phase 2 emissionsstandards. For Phase 2 certified engines, the Emissions CompliancePeriod referred to on the Emissions Compliance label indicates thenumber of operating hours for which the engine has been shown tomeet Federal emissions requirements.

Engines that are certified to meet the California Air Resources Board(CARB) Tier 2 Emissions Standard must display informationregarding the Emissions Durability Period and the Air Index.
