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.

SAFETY

WARNING

Starting engine creates sparking.

Gasoline and its vapors are extremely

flammable and explosive.

Sparking can ignite nearby flammable

gases.

Fire or explosion can cause severe burns

or death.

Explosion and fire could result.

WHEN ADDING FUEL

• Turn engine OFF and let engine cool at least 2

minutes before removing gas cap.

• If there is natural or LP gas leakage in area, do not

start engine.

• Do not use pressurized starting fluids because

vapors are flammable.

• 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.

WARNING

Rapid retraction of starter cord (kickback) will

pull hand and arm toward engine faster than

you can let go.

WHEN STARTING ENGINE

• Make sure spark plug, muffler, fuel cap and air

cleaner are in place.

Broken bones, fractures, bruises or sprains

could result.

• Do not crank engine with spark plug removed.

• If fuel spills, wait until it evaporates before starting

engine.

• When starting engine, pull cord slowly until

resistance is felt, then pull rapidly.

• If engine floods, set choke to OPEN/RUN position,

place throttle in FAST and crank until engine starts.

• 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.

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

WARNING

valve OFF.

Rotating parts can contact or entangle

hands, feet, hair, clothing, or accessories.

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.

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.

SAFETY

WARNING

Engines give off carbon monoxide, an

odorless, colorless, poison gas.

Unintentional sparking can result in fire or

electric shock.

Breathing carbon monoxide can cause

nausea, fainting or death.

Unintentional start-up can result in en-

tanglement, traumatic amputation, or lac-

eration.

• Start and run engine outdoors.

• Do not start or run engine in enclosed area, even if

doors or windows are open.

BEFORE PERFORMING ADJUSTMENTS OR

REPAIRS

• Disconnect spark plug wire and keep it away from

spark plug.

WARNING

Running engines produce heat. Engine

parts, especially muffler, become extremely

hot.

• Disconnect battery at negative terminal (only

engines with electric start).

Severe thermal burns can occur on contact.

WHEN TESTING FOR SPARK

• Use approved spark plug tester.

Combustible debris, such as leaves, grass,

brush, etc. can catch fire.

• Do not check for spark with spark plug removed.

• 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.

ENGINE INFORMATION

TECHNICAL INFORMATION

POWER RATINGS: The power ratings for an individual engine

model are initially developed by starting with SAE (Society of Auto-

motive Engineers) code J1940 (Small Engine Power & Torque

Rating Procedure) (Revision 2002-05). Given both the wide array

of products on which our engines are placed, and the variety of en-

vironmental issues applicable to operating the equipment, it may

be that the engine you have purchased will not develop the rated

horsepower when used in a piece of power equipment (actual “on-

site” power). This difference is due to a variety of factors including,

but not limited to, the following: differences in altitude, tempera-

ture, barometric pressure, humidity, fuel, engine lubrication, maxi-

mum governed engine speed, individual engine to engine variabil-

ity, design of the particular piece of power equipment, the manner

in which the engine is operated, engine run-in to reduce friction

and clean out of combustion chambers, adjustments to the valves

and carburetor, and other factors. The power ratings may also be

adjusted based on comparisons to other similar engines utilized

in similar applications, and will therefore not necessarily match the

values derived using the foregoing codes.

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

TYPE OF OIL TO USE

• 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).

• Do not use special additives.

• Choose a viscosity according to the table opposite.

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.

Note: Synthetic oil meeting ILSAC GF-2, API

certification mark and API service symbol

(shown at left) with “SJ/CF ENERGY CON-

SERVING” or higher, is an acceptable oil at all

temperatures. Use of synthetic oil does not

alter required oil change intervals.

CHECKING AND ADDING OIL

CAUTION: If engine is equipped with OIL GARD,

and if engine runs low on oil, light on engine warns of

low oil level. If light flickers and engine cannot be

started, or has stopped and cannot be restarted, add

oil. Fill to point of overflowing at oil fill cap or to FULL

mark on dipstick. Do not over-fill.

• 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: If this engine is equipped with gear reduction, see gear reduction oil filling instructions on page 12.

FUEL

TYPE OF FUEL TO USE

• Use clean, fresh, regular unleaded gasoline with a

minimum of 77 octane. Fresh fuel prevents gum from

forming in the fuel system or on essential carburetor parts.

Purchase fuel in quantity that can be used within 30 days.

CAUTION: Some fuels, called oxygenated or

reformulated gasoline, are gasoline blended with

alcohols or ethers. Excessive amounts of these

blends can damage the fuel system or cause

performance problems. If any undesirable operat-

ing 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.

• For engine protection use Briggs & Stratton Gasoline

Additive available from your Authorized Briggs &

Stratton Dealer (P/N 5041 or single use pouch).

• This engine is certified to operate on gasoline. Exhaust

B&S is not liable to cover failures of War-

ranted Parts caused by the use of add-on,

subsequent purchaser that the Warranted

Parts shall be free from defects in materials

and workmanship which caused the failure

of the Warranted Parts for a period of two

years from the date the engine is delivered to

Coverage under this warranty extends only

to the parts listed below (the emission con-

were present on the engine purchased.

which is scheduled for replacement as re-

quired maintenance shall be warranted as to

defects only for the period of time up to the

first scheduled replacement for that part. Any

mance and durability may be used in the per-

formance of any maintenance or repairs.

mance of all required maintenance, as de-

fined in the B&S Operating and Maintenance
