Engine Power Rating information
The gross power rating for individual gas engine models is labeled in accordance with SAE
(Society of Automotive Engineers) 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 equip-
ment (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.), ap-
plication 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.
