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 .
*This pressure washer is rated in accordance to the Pressure Washer Manufacturers' Association (PWMA) standard PW101-2010
(Testing and Rating Performance of Pressure Washers) .
