BEFORE OPERATING ENGINE
• Read entire Operating & Maintenance Instructions
AND the instructions for the equipment this engine
powers.*
• Failure to follow instructions could result in serious
injury or death.
* Briggs & Stratton does not necessarily know what equipment this engine will power. For that reason, you should carefully
read and understand the operating instructions for the equipment on which your engine is placed.
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.
MM /DD/YYYY
THE OPERATING & MAINTENANCE INSTRUCTIONS CONTAIN SAFETY INFORMATION TO
• Make you aware of hazards associated with engines
• Inform you of the risk of injury associated with those
hazards, and
• Tell you how to avoid or reduce the risk of injury.

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-ventilated area.
• Do not overfill fuel tank. Fill tank to approximately 1-1/2
inches 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-off valve
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
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
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
Rotating parts can contact or entangle
hands, feet, hair, clothing, or accessories.
Traumatic amputation or severe laceration can result.
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.
• 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.

SAFETY
WARNING
If engine is warm DO NOT remove radiator
cap.
Escaping steam can cause burns.
• Do not touch hot radiator, or open reservoir when engine is
running
• Allow engine to cool before removing radiator cap, changing,
or adding coolant.
WARNING
Never remove radiator cap or radiator
reservoir cap while the engine is hot or
running. Severe thermal burns or injury
can occur by escaping steam or hot
engine coolant.
• Stop engine and allow to cool before removing radiator or
reservoir cap.
• To remove reservoir cap after engine is cool, place a thick
cloth over cap and remove it slowly.
• To remove radiator cap after engine is cool, place a thick
cloth over cap and rotate it slowly counter-clockwise to the
first stop. Pressurized steam may emit from the cap, stand
back to avoid injury. Once all pressure is released, rotate cap
counter-clockwise while pushing down on cap to remove.
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
• Disconnect spark plug wire and keep it away from spark
plug.
• Disconnect battery at negative terminal.
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.
WARNING
Briggs & Stratton does not approve or authorize the use of
these engines on 3-wheel All Terrain Vehicles (ATVs), motor
bikes, fun/recreational go-karts, aircraft products or vehicles
intended for use in competitive events. Use of these engines in
such applications could result in property damage, serious
injury (including paralysis), or even death.
ENGINE INFORMATION
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). 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 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 horsepower). 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.

OIL
OIL CAPACITY
Oil capacity, including oil filter, is 3.5 quarts or 3.3 liters.
TYPE OF OIL TO USE
• Use high quality detergent oil classified “For Service SH, SJ” or
higher.
• Do not use special additives with recommended oils.
• Do not mix oil with gasoline.
• Choose a viscosity according to the table opposite.
CAUTION: This engine is shipped from Briggs &
Stratton without oil
engine. If you start the engine without oil, the engine
will be damaged beyond repair and will not be
covered under warranty.
CHECKING AND ADDING OIL
• Check oil level before starting the engine.
• Check level daily, or after every eight (8) hours.
• Keep oil level at FULL.
• Do not overfill.

Note: After filling with or changing oil, start and run engine at
idle for 5 minutes. Shut engine off. Wait 3 minutes and check oil
level. Add oil, if required, to bring level to Full mark on dipstick.
Bring oil
level to F
mark
on dipstick.
[1]. Place equipment level.
Clean around oil fill.
[5]. Replace dipstick firmly.
[2]. Remove dipstick and wipe
with clean cloth.
[3]. Then replace dipstick, and
remove to check oil level.
CAUTION: When filling engine or adding oil.
To prevent engine damage upon
start-up, proper venting is necessary
when filling engine with oil or adding oil.
In addition to ensuring a level engine,
removing dipstick, and pouring oil
, there must be clearance
slowly
between the oil fill device and the oil fill
hole in the valve cover as shown. This
clearance is necessary to permit
venting when filling, which prevents oil
from overrunning into breather.
[4]. If oil is required, remove dipstick to allow
proper venting and pour oil slowly. Fill to
FULL line on dipstick. Recheck.
