ENGINETECHNICALINFORMATION
This is a single cylinder, overhead valve (OHV), air cooled
engine. It is a low emissions engine.
In the State of California, Model 120000 engines are certified
by the California Air Resources Board to meet emissions
standards for 125 hours. Such certification does not grant
the purchaser, owner or operator of this engine any
additional warranties with respect to the performance or
operational life of this engine. The engine is warranted solely
according to the product and emissions warranties stated
elsewhere in this manual.
Power Ratings
The gross power rating for individual gas engine models is
labeled in accordancewith SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque
Rating Procedure), and rating performance has been
obtained and corrected in accordancewith SAEJ1995
(Revision 2002-05). Torque values are derived at 3060 RPM;
horsepower values are derived at 3600 RPIVI. A ctual 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 conditions (temperature, humidity,
altitude), and engine-to-engine variability. Dueto
manufacturing and capacity limitations, Briggs & Stratton
may substitute an engine of higher rated power for this
Series engine.
This pressure washer is rated in accordanceto the Pressure
Washer Manufacturers Association (PWIVIA)standard PW101
(Testing and Rating Performance of Pressure Washers).

NOTICE For practical operation, the engine load should not
exceed85% of rated power. Engine power will decrease
3-1/2% for each 1,000 feet (300 meters) above sea level and
1% for each 10° F (5.6° C) above 77° F (25° C). It should
operate satisfactorily at an angle up to 15°.
