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-formingexhaust 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, theSmart-Fillcontainer 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

After July 1, 2000, Look For Emissions Compliance Period On

Engine Emissions Compliance Label

After July 1, 2000 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, B = 250 hours and A = 500 hours. For engines of 225 cc or more, Category C = 250 hours, B = 500 hours and A = 1000 hours.

The displacement of Model Series 190000 engines is 319 cc. The displacement of Model Series 280000 engines is 465 cc.

This is a generic representation of the emission label typically found on a certified engine.

SAFETY

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-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

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.

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.

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 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.

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.

4

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

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-coveredunimproved 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.

SAFETY

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.

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.
