SAFETY  
WARNING  
WARNING  
Engines give off carbon monoxide, an odorless,  
colorless, poison gas.  
Rotating parts can contact or entangle hands, feet,  
hair, clothing, or accessories.  
Breathing carbon monoxide can cause nausea,  
fainting or death.  
Traumatic amputation or severe laceration can  
result.  
Start and run engine outdoors.

doors or windows are open.  
Do not wear loose-fitting clothing, dangling  
drawstrings or items that could become caught.  
WARNING  
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.  
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.  
Allow muffler, engine cylinder and fins to cool  
before touching.  
Remove accumulated combustibles from muffler  
When starting engine, pull cord slowly until  
area and cylinder area.  
resistance is felt, then pull rapidly.  
Install and maintain in working order a spark  
arrester before using equipment on forest-covered,  
grass-covered, brush-covered unimproved land.

30W, Part Number 100005 (20 oz) or 100028 (48 oz).  
Do not use special additives.  
*
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.  
Choose a viscosity according to the table opposite.  
Note: Synthetic oil meeting ILSAC GF-2, API  
certification mark and API service symbol  
(shown at left) with SJ/CF ENERGY CON-  
SERVINGor higher, is an acceptable oil at all  
temperatures. Use of synthetic oil does not  
alter required oil change intervals.  
** 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.  
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.  
CAUTION: Do not overfill. Overfilling with oil may cause:  
Smoking,  
Hard starting,  
Spark plug fouling, or  
Oil saturation of air filter.

FUEL  
This engine is certified to operate on gasoline. Exhaust  
TYPE OF FUEL TO USE  
Emission Control System: EM (Engine Modifications).  
Use clean, fresh, regular unleaded gasoline with a  
minimum of 85 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.  
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).  
CAUTION: Some fuels, called oxygenated or reformu-  
lated 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 operating symptoms occur, use gasoline  
with a lower percentage of alcohol or ether.  
ADDING FUEL  
WARNING  
Fuel Fill  
Note: Remove and discard blue plug in fuel fill.  
[4] Remove cap. Fill tank to approximately 1-1/2 inches  
below top of neck to allow for fuel expansion. Be  
careful not to overfill.  
[1] Fill fuel tank outdoors or in well-ventilated area,  
away from sparks, open flames, pilot lights, heat,  
and other ignition sources.  
Briggs & Stratton Smart-fill fuel can fills to the  
correct level and automatically shuts off, reducing  
spills and emissions.  
[2] If fuel spills, wait until it evaporates before starting  
engine.

Briggs & Stratton Corporation (B&S), the California Air Resources Board (CARB)  
and the United States Environmental Protection Agency (U.S. EPA)  
Emission Control System Warranty Statement (Owner’s Defect Warranty Rights and Obligations)  
EMISSION CONTROL WARRANTY COVERAGE IS APPLICABLE  
TO CERTIFIED ENGINES PURCHASED IN CALIFORNIA IN 1995  
AND THEREAFTER, WHICH ARE USED IN CALIFORNIA, AND  
TO CERTIFIED MODEL YEAR 1997 AND LATER ENGINES  
WHICH ARE PURCHASED AND USED ELSEWHERE IN THE  
UNITED STATES.  
California and United States Emission Control Defects Warranty Statement  
The California Air Resources Board (CARB), U.S. EPA and B&S are  
pleased to explain the Emission Control System Warranty on your  
model year 2000 and later small off-road engine (SORE). In California,  
new small off-road engines must be designed, built and equipped to  
meet the State’s stringent anti-smog standards. Elsewhere in the  
United States, new non-road, spark-ignition engines certified for model  
year 1997 and later, must meet similar standards set forth by the U.S.  
EPA. B&S must warrant the emission control system on your engine for  
the periods of time listed below, provided there has been no abuse, ne-  
glect or improper maintenance of your small off-road engine.  
Your emission control system includes parts such as the carburetor,  
air cleaner, ignition system, muffler and catalytic converter. Also in-  
cluded may be connectors and other emission related assemblies.  
Where a warrantable condition exists, B&S will repair your small off-  
road engine at no cost to you including diagnosis, parts and labor.  
Briggs & Stratton Emission Control Defects Warranty Coverage  
Small off-road engines are warranted relative to emission control  
parts defects for a period of two years, subject to provisions set forth  
below. If any covered part on your engine is defective, the part will be  
repaired or replaced by B&S.  
Owner’s Warranty Responsibilities  
As the small off-road engine owner, you are responsible for the per-  
formance of the required maintenance listed in your Operating and  
Maintenance Instructions. B&S recommends that you retain all your  
receipts covering maintenance on your small off-road engine, but  
B&S cannot deny warranty solely for the lack of receipts or for your  
failure to ensure the performance of all scheduled maintenance.  
As the small off-road engine owner, you should however be aware  
that B&S may deny you warranty coverage if your small off-road en-  
gine or a part has failed due to abuse, neglect, improper mainte-  
nance or unapproved modifications.  
You are responsible for presenting your small off-road engine to an  
Authorized B&S Service Dealer as soon as a problem exists. The  
undisputed warranty repairs should be completed in a reasonable  
amount of time, not to exceed 30 days.  
If you have any questions regarding your warranty rights and re-  
sponsibilities, you should contact a B&S Service Representative at  
1-414-259-5262.  
The emission warranty is a defects warranty. Defects are judged on  
normal engine performance. The warranty is not related to an in-use  
emission test.

ranted as to defects for the warranty period. Any Warranted Part  
which is scheduled for replacement as required maintenance  
shall be warranted as to defects only for the period of time up to  
the first scheduled replacement for that part. Any replacement

ered to a retail purchaser.

About your engine warranty: (see next page for statement of LIMITED WARRANTY).  
Briggs & Stratton welcomes warranty repair and apologizes  
to you for being inconvenienced. Any Authorized Service  
Dealer may perform warranty repairs. Most warranty repairs  
are handled routinely, but sometimes requests for warranty  
service may not be appropriate. For example, warranty would  
not apply if engine damage occurred because of misuse, lack  
of routine maintenance, shipping, handling, warehousing or  
improper installation. Similarly, warranty is void if the serial  
number of the engine has been removed or the engine has  
been altered or modified.  
4. Parts which are scored or broken because an engine was  
operated with insufficient or contaminated lubricating oil,  
or an incorrect grade of lubricating oil (check oil level daily  
or after every 8 hours of operation. Refill when necessary  
and change at recommended intervals.) OIL GARD  
may not shut down running engine. Engine damage may  
occur if oil level is not properly maintained. Read Operat-  
ing & Maintenance Instructions.  
5. Repair or adjustment of associated parts or assemblies  
such as clutches, transmissions, remote controls, etc.,  
which are not manufactured by Briggs & Stratton.  
If a customer differs with the decision of the Service Dealer, an  
investigation will be made to determine whether the warranty  
applies. Ask the Service Dealer to submit all supporting facts to  
his Distributor or the Factory for review. If the Distributor or the  
Factory decides that the claim is justified, the customer will be  
fully reimbursed for those items that are defective. To avoid  
misunderstanding which might occur between the customer  
and the Dealer, listed below are some of the causes of engine  
failure that the warranty does not cover.  
6. Damage or wear to parts caused by dirt, which entered  
the engine because of improper air cleaner maintenance,  
re-assembly, or use of a non-original air cleaner element  
or cartridge. (At recommended intervals, clean and re-oil  
the Oil-Foam element or the foam pre-cleaner, and re-  
place the cartridge.) Read Operating & Maintenance  
Instructions.  
7. Parts damaged by overspeeding, or overheating caused  
by grass, debris, or dirt, which plugs or clogs the cooling  
fins, or flywheel area, or damage caused by operating the  
engine in a confined area without sufficient ventilation.  
(Clean fins on the cylinder, cylinder head and flywheel at  
recommended intervals.) Read Operating & Maintenance  
Instructions.  
Normal wear:  
Engines, like all mechanical devices, need periodic parts ser-  
vice and replacement to perform well. Warranty will not cover  
repair when normal use has exhausted the life of a part or an  
engine.  
Improper maintenance:  
8. Engine or equipment parts broken by excessive vibration  
caused by a loose engine mounting, loose cutter blades,  
unbalanced blades or loose or unbalanced impellers, im-  
proper attachment of equipment to engine crankshaft,  
overspeeding or other abuse in operation.  
The life of an engine depends upon the conditions under  
which it operates, and the care it receives. Some applications,  
such as tillers, pumps and rotary mowers, are very often used  
in dusty or dirty conditions, which can cause what appears to  
be premature wear. Such wear, when caused by dirt, dust,  
spark plug cleaning grit, or other abrasive material that has  
entered the engine because of improper maintenance, is not  
covered by warranty.  
9. A bent or broken crankshaft, caused by striking a solid ob-  
ject with the cutter blade of a rotary lawn mower, or exces-  
sive v-belt tightness.  
10. Routine tune-up or adjustment of the engine.  
This warranty covers engine related defective material  
and/or workmanship only, and not replacement or refund  
of the equipment to which the engine may be mounted.  
Nor does the warranty extend to repairs required be-  
cause of:  
1. PROBLEMS CAUSED BY PARTS THAT ARE NOT  
ORIGINAL BRIGGS & STRATTON PARTS.  
2. Equipment controls or installations that prevent starting,  
cause unsatisfactory engine performance, or shorten en-  
gine life. (Contact equipment manufacturer.)  
Warranty is available only through service dealers which  
have been authorized by Briggs & Stratton Corporation.  
Your nearest Authorized Service Dealer is listed in the  
“Yellow Pages ” of your telephone directory under “En-  
gines, Gasoline” or “Gasoline Engines,” “Lawn Mow-  
ers,” or similar category.  
3. Leaking carburetors, clogged fuel pipes, sticking valves,  
or other damage, caused by using contaminated or stale  
fuel. (Use clean, fresh, lead-free gasoline and Briggs &  
Stratton gasoline stabilizer, Part No. 5041.)
