Power Rating: 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; horse-
power values are derived at 3600 RPM. Net power values are taken with exhaust and air cleaner installed whereas gross
power values are collected without these attachments. Actual gross engine power will be higher than net engine power and is
affected by, among other things, ambient operating conditions and engine-to-engine variability. Given the wide array of prod-
ucts on which engines are placed, the gas engine may not develop the rated gross power when used in a given piece of
power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine components
(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.
