Engine Power Rating Information
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive En-
gineers) 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 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 manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this
Series engine.
