TECHNICAL INFORMATION

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 perfor-
mance 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 condi-
tions (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.

used with the alert symbol to indicate the likelihood and
the potential severity of injury. In addition, a hazard
symbol may be used to represent the type of hazard.
DANGER indicates a hazard which, if not
avoided, will result in death or serious
injury.
WARNING indicates a hazard which, if not
avoided, could result in death or serious
injury.
CAUTION indicates a hazard which, if not
avoided, might result in minor or moderate
