Engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and
1% for each 10°F (5.6°C) above 77° F (25°C). The engine will operate satisfactorily
at an angle up to 15°. Refer to the equipment Operator's Manual for safe permitted
operating limits on slopes.

Power Ratings
The gross power rating for individual gasoline engine models is labeled in accordance
with SAE (Society of Automotive Engineers) code J1940 Small Engine Power & Torque
Rating Procedure, and is rated in accordance with SAE J1995. Torque values are
derived at 2600 RPM for those engines with "rpm" called out on the label and 3060 RPM
for all others; horsepower values are derived at 3600 RPM. The gross power curves
can be viewed at www.BRIGGSandSTRATTON.COM. 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 products on which engines are placed, the gasoline
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 engine.
