* 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.

Engine Power Rating Information
The gross power rating for individual gas engine models is
labeled in accordance with SAE (Society of Automotive Engi-
neers) 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 operat-
ing 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 vari-
ety 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 vari-
ability. Due to manufacturing and capacity limitations, Briggs
& Stratton may substitute an engine of higher rated power for
this Series engine.
