SAFETY
WARNING
Fuel and its vapors are extremely flammable
and explosive.
Fire or explosion can cause severe burns or
death.
WHEN FUELING
• Turn engine OFF and let engine cool at least 2 minutes
before removing cap or refueling engine.
• Fill fuel tank outdoors or in well-ventilated area.
• On GASOLINE operated engines, do not overfill fuel
tank. Fill tank to approximately 1-1/2 inches below top of
neck to allow for fuel expansion.
• Keep fuel 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, and firmly secured by equipped fasteners.
• Do not crank engine with spark plug, air cleaner cartridge
or air cleaner cover removed.
• If fuel spills, wait until it evaporates before starting engine.
• If GASOLINE 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.
WARNING
Gaseous fuels are extremely flammable
and readily form explosive air-vapor mixtures at ambient temperatures.
IF YOU SMELL GAS:
• DO NOT start the engine.
• DO NOT actuate any electrical switches.
• DO NOT use the phone in the vicinity.
• Evacuate the area.
• Contact the gas supplier or fire department.
REMEMBER:
• LPG vapor is heavier than air and trends to collect in low
areas. NG vapor is lighter than air and tends to collect in
high areas. Both may travel to remote locations.
• Keep all flames, sparks, pilot lights, and other ignition
sources away from the area where the engine is operated
or repaired.
• DO NOT smoke when operating or repairing the engine.
• DO NOT store gasoline or other flammable vapors or
liquids in the vicinity of the engine.
• BEFORE doing any service work to the engine, shut off
the gas supply.
• After initial installation or servicing, check for gas leaks.
DO NOT use an open flame. Apply very soapy water or
leak test solution with a brush and look for bubbles.
• Keep the equipment and the area surrounding the engine
free of debris.
• Install the fuel system according to applicable fuel/gas
codes.
WHEN TRANSPORTING EQUIPMENT
• On GASOLINE engine, transport with fuel tank EMPTY or
with fuel shut-off valve OFF.
• On NATURAL / LIQUID PETROLEUM (LP) GAS
engines transport with fuel cylinder empty or valve
closed, or tank disconnected.
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
Wear eye protection when doing repair work.
Frostbite can result from skin/eye contact with
leaking LP liquid.
• Installation, adjustment and repair work should be done by a
qualified technician.
• Flexible supply lines should be checked regularly to make
sure they are in good condition. Replace damaged or
leaking components.

SAFETY
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.
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.
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-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.
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-fitting clothing, dangling drawstrings or
items that could become caught.
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.
Unintentional start-up can 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.

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 and engine-to-engine variability. Given both the wide

Note: For practical operation, the horsepower loading should not
exceed 85% of rated horsepower. Engine power will decrease
3-1/2% for each 1,000 feet (300 meters) above sea level and 1%
for each 10° F (5.6° C) above 77° F (25° C). Engine will operate
satisfactorily at an angle up to 15°.
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 (actual “on-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), and engine-to-engine variability. Due to manufacturing
and capacity limitations, Briggs & Stratton may substitute an
engine of higher rated power for this Series engine.

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
* CAUTION: Air cooled engines run hotter than
automotive engines. The use of non-synthetic
multi-viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40° F (4° C) will result in higher
than normal oil consumption. When using a
multi-viscosity oil, check oil level more frequently.
** CAUTION: SAE 30 oil, if used below 40° F (4° C), will
result in hard starting and possible engine bore
damage due to inadequate lubrication.
