Engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and
1% for each 10° F (5.6° C) above 77° F (25° C). The engine will operate satisfactorily at
an angle up to 15°. Refer to the equipment operator's manual for safe allowable operating
limits on slopes.

We recommend that you see any Briggs & Stratton Authorized Dealer for all maintenance
and service of the engine and engine parts.
Power Ratings: The gross power rating for individual gasoline engine models is labeled
in accordance with SAE (Society of Automotive Engineers) code J1940 Small Engine
Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque
values are derived at 2600 RPM for those engines with “rpm” called out on the label and
3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power
curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken
with exhaust and air cleaner installed whereas gross power values are collected without
these attachments. Actual gross engine power will be higher than net engine power and
is affected by, among other things, ambient operating conditions and engine-to-engine
variability. Given the wide array of products on which engines are placed, the gasoline
engine may not develop the rated gross power when used in a given piece of power
equipment. This difference is due to a variety of factors including, but not limited to, the
variety of engine components (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 engine.

Australian Consumer Law. You are entitled to a replacement or refund for a major

consumer. "Consumer use" means personal residential household use by a retail consumer.
"Commercial use" means all other uses, including use for commercial, income producing
or rental purposes. Once an engine has experienced commercial use, it shall thereafter
be considered as a commercial use engine for purposes of this warranty.

date at the time warranty service is requested, the manufacturing date of the product
will be used to determine the warranty period. Product registration is not required
to obtain warranty service on Briggs & Stratton products.
About Your Warranty
This limited warranty covers engine-related material and/or workmanship issues only, and
not replacement or refund of the equipment to which the engine may be mounted. Routine
maintenance, tune-ups, adjustments, or normal wear and tear are not covered under this
warranty. Similarly, warranty is not applicable if the engine has been altered or modified
or if the engine serial number has been defaced or removed. This warranty does not cover
engine damage or performance problems caused by:
1. The use of parts that are not original Briggs & Stratton parts;
2. Operating the engine with insufficient, contaminated, or an incorrect grade of
lubricating oil;
3. The use of contaminated or stale fuel, gasoline formulated with ethanol greater than
10%, or the use of alternative fuels such as liquefied petroleum or natural gas on
engines not originally designed/manufactured by Briggs & Stratton to operate on
such fuels;
4. Dirt which entered the engine because of improper air cleaner maintenance or re-
assembly;
5. Striking an object with the cutter blade of a rotary lawn mower, loose or improperly
installed blade adapters, impellers, or other crankshaft coupled devices, or excessive
v-belt tightness;
6. Associated parts or assemblies such as clutches, transmissions, equipment controls,
etc., which are not supplied by Briggs & Stratton;
7. Overheating due to grass clippings, dirt and debris, or rodent nests which plug or
clog the cooling fins or flywheel area, or by operating the engine without sufficient
ventilation;
8. Excessive vibration due to over-speeding, loose engine mounting, loose or unbalanced
cutter blades or impellers, or improper coupling of equipment components to the
crankshaft;
9. Misuse, lack of routine maintenance, shipping, handling, or warehousing of equipment,
or improper engine installation.
Warranty service is available only through Briggs & Stratton Authorized Service
Dealers. Locate your nearest Authorized Service Dealer in our dealer locator map
