Safety References
The safety alert symbol 
is used to identify safety information about hazards that can result in personal injury. A signal word (DANGER, WARNING, or CAUTION) is used with the alert symbol to indicate the likelihood and the potential severity of injury. In addition, a hazard symbol may be used to represent the type of hazard.
DANGER indicates a hazard which, if not avoided, will result in death or serious injury.
WARNING indicates a hazard which, if not avoided, could result in death or serious injury.
CAUTION indicates a hazard which, if not avoided, might result in minor or moderate injury.
CAUTION, when used without the alert symbol, indicates a situation that could result in damage to the engine.
This manual contains safety information to make you aware of
the hazards and risks associated with engines, and how to avoid them. Because Briggs & Stratton does not necessarily know what equipment this engine will power, it is important that you read and understand these instructions and the instructions for the equipment this engine powers.

Safety Information
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
WHEN ADDING FUEL
STurn engine OFF and let engine cool at least 2 minutes before removing gas cap.
SFill fuel tank outdoors or in well-ventilated area.
SDo not overfill fuel tank.
SKeep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources.
SCheck fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
WHEN STARTING ENGINE
SMake sure spark plug, muffler, fuel cap and air cleaner are in place.
SDo not crank engine with spark plug removed.
SIf fuel spills, wait until it evaporates before starting engine.
SIf engine floods, set choke to OPEN/RUN position, place throttle in FAST and crank until engine starts.
WHEN OPERATING EQUIPMENT
SDo not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
STransport with fuel tank EMPTY.
WHEN STORING GASOLINE OR EQUIPMENT WITH FUEL IN TANK
SStore away from furnaces, stoves, water heaters or other appliances that have pilot light or other ignition source because they can ignite gasoline vapors.
WARNING
Engines give off carbon monoxide, an odorless, colorless, poison gas.
Breathing carbon monoxide can cause nausea, fainting or death.
SStart and run engine outdoors.
SDo 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.
SIf there is natural or LP gas leakage in area, do not start engine.
SDo not use pressurized starting fluids because vapors are flammable.
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.
SWhen starting engine, pull cord slowly until resistance is felt, then pull rapidly.
SDirect coupled equipment components such as, but not limited to, blades, impellers, pulleys, sprockets, etc., must be securely attached.

SOperate equipment with guards in place.
SKeep hands and feet away from rotating parts.
STie up long hair and remove jewelry.
SDo not wear loose-fitting clothing, dangling drawstrings or items that could become caught.
WARNING

Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
SAllow muffler, engine cylinder and fins to cool before touching.
SRemove accumulated combustibles from muffler area and cylinder area.
SInstall 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
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
SDisconnect spark plug wire and keep it away from spark plug.
SDisconnect battery at negative terminal (only engines with electric start.)
SDo not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation.
SDo not tamper with governor spring, links or other parts to increase engine speed.
SUse only correct tools.
WHEN TESTING FOR SPARK
SUse approved spark plug tester.
SDo not check for spark with spark plug removed.
