Power Ratings Disclaimer

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.

• Gasoline and oil are hazardous waste. Dispose of these materials properly.

• Do not pour gas or oil into the ground or into household garbage. Contact your local recycling authority.

• Some recycling centers will accept gas and oil and will recondition it or recycle it safely. Your city's government ofﬁcial should be

able to direct you to the right recycling place. Then, call the recycling location in advance to see if they have any instructions

that you'll need to follow.

• If disposing of entire mower, contact your local metal scrap yard.
