** We recommend that you see any Briggs & Stratton Authorized
Dealer for all maintenance and service of the water pump. Use
only genuine Briggs & Stratton parts.
Power Ratings: 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 performance 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. 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 gas 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 Series engine.
Tested in accordance with CPB standards for self-priming centrifugal pumps with clear water at sea level.
