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 andengine-to-enginevariability. 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 (actualon-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), andengine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.

In the state of California, Model 50000, 85400, 86400, 117400, 118400, 138400 engines are certified by the California Air Resources Board to meet emissions standards for 125 hours; Model 185400, 187400, 235400, 237400, 245400, 246400, 247400 for 250 hours. Such certification does not grant the purchaser, owner or operator of this engine any additional warranties with respect to the performance or operational life of this engine. This engine is warranted solely according to the product and emissions warranties stated elsewhere in this manual.

1

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

WHEN ADDING GASOLINE

Turn engine OFF and let engine cool at least 2 minutes before refueling engine.

Fill fuel tank outdoors or in well-ventilatedarea.

Do not overfill fuel tank. Fill tank to approximately 1-1/2inches 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.

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.

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

Transport with fuel tank EMPTY or with fuel shut-offvalve OFF, and/or fuel tank empty.

WHEN STORING FUEL OR EQUIPMENT

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

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.

Engine should be kept clean to reduce the risk of overheating and ignition of accumulated debris. Clean engine when it is cold, especially in the muffler and manifold areas.

Install and maintain in working order a spark arrester before using equipment on forest-cov-ered,grass-covered,brush-coveredunimproved land. (The state of California Public Resources Code Section 4442 requires a spark arrester in working order.) Other states may have similar laws. Federal laws apply on federal land.

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, impellers, pulleys, sprockets, etc., must be securely attached.

WARNING

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

Breathing carbon monoxide can cause nausea, fainting or death.

Start and run engine outdoors in a well ventilated area.

Do not start or run engine in enclosed area, even if doors or windows are open.

WARNING

Unintentional sparking can result in fire or electric shock.

Unintentional start-upcan result in entanglement, traumatic amputation, or laceration.

BEFORE PERFORMING ADJUSTMENTS

OR REPAIRS

Disconnect battery at negative () terminal.

Disconnect spark plug wire and keep it away from spark plug.

WHEN TESTING FOR SPARK

Use only Briggs & Stratton Spark Plug Tester.

DO NOT check for spark with spark plug removed.

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.

Servicing of products fueled by Natural Gas (NG) or Liquid Petroleum Gas (LPG) may require licensing or permits issued by state, provincial, and/or local governments.

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-fittingclothing, dangling drawstrings or items that could become caught.

OIL RECOMMENDATIONS

Fig. 2

Engine shipped from Briggs & Stratton without oil.Before starting engine, fill with oil. Do notover-fill.

Use a high quality detergent oil classified For Service SF, SG, SH, SJ" or higher such as Briggs & Stratton 30W, Part Number 100005 (20 oz.) or 100028 (48 oz.). Use no special additives with recommended oils. Do not mix oil with gasoline.

Choose the SAE viscosity grade of oil from this chart that matches the starting temperature anticipated before the next oil change.

Note: Synthetic oil meeting ILSAC

GF-2,API certification mark and API ser-

vice symbol (shown at left) with SJ/CF

ENERGY CONSERVING" or higher, is an

acceptable oil at all temperatures. Use of

synthetic oil does not alter required oilchange intervals.

*Air cooled engines run hotter than automotive engines. The use of non-syntheticmulti-viscosity

oils (5W-30,10W-30,etc.) in temperatures above 40° F (4° C) will result in higher than normal oil consumption. When using amulti-vis-cosity oil, check oil level more frequently.

**SAE 30 oil, if used below 40° F (4° C), will result in hard starting and possible engine bore damage due to inadequate lubrication.

FUEL RECOMMENDATIONS

THE GASOLINE ENGINE IS CERTIFIED TO OPERATE ON GASOLINE. Exhaust Emission Control System: EM (Engine Modifications).

Use clean, fresh, lead-free gasoline with a minimum of 85 octane. Leaded gasoline may be used if it is commercially available and if unleaded is unavailable. Purchase fuel in quantity that can be used within 30 days. See Storage.

In U.S.A. leaded gasoline may not be used. Some fuels, called oxygenated or reformulated gasolines, are gasolines 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.

Do not use gasoline which contains Methanol. Do not mix oil with gasoline.

Check fuel level

WARNING

Before refueling, allow engine to cool 2 minutes.

Clean around fuel fill before removing cap to refuel. Fill tank to approximately 1-1/2inches below top of neck to allow for fuel expansion. Be careful not to overfill.

STORAGE

Gasoline 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 gasoline 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.

Storage Procedures for Gas/LPG/NG engines.

Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emissions Standards must display information regarding the Emissions Durability Period and the Air Index. Briggs & Stratton makes this information available to the consumer on our emissions labels. The engine emissions 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 emissions compliant for 125 hours of actual engine running time.

Intermediate:

Engine is certified to be emissions compliant for 250 hours of actual engine running time.

Extended:

Engine is certified to be emissions compliant for 500 hours of actual engine running time. For example, a typical walkbehind 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 emissions 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 emissions 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 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.

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.

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 and 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.

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 anon-original

air cleaner element or cartridge. At recommended intervals, clean and/or replace the filter as stated in the Operator’s Manual.

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 damage caused by operating the engine in a confined area without sufficient ventilation. Clean engine of debris at recommended intervals as stated in the Operator’s Manual.

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, over-speedingor other abuse in operation.

9.A bent or broken crankshaft, caused by striking a solid object with the cutter blade of a rotary lawn mower, or excessive v-belttightness.

10.Routine tune-upor 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 the use of alternate fuels such as, liquified petroleum, natural gas, altered gasolines, etc.
