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 cor-
rected 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 operating
conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the va-
riety 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 power). 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 manu-
facturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
