*Actual sustained equipment horsepower will likely be lower due to
operating limitations and environmental factors.
**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 operating 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.
