Engine Power Rating Information
The gross power rating for individualgas engine models is labeled in accordance with SAE (So-
ciety of Automo-tive Engineers) code Jl1940 (Small Engine Power & Torque Rating Procedure),
and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision
2002-5). Actual gross engine power will be lower and is affected by, among other things, ambi-
ent operating conditionsand 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 horsepower). This difference is due to a variety of factors
cluding, 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, Bdggs & Stratton
may substitutean engine of higherrated power for this Series engine.
