ENGINETECHNICALINFORMATION
This is a single cylinder, overheadvalve (OHV), air cooled
engine. It is a low emissions engine.
In the State of California, Model 120000 enginesare certified
by the California Air Resources Boardto meet emissions
standardsfor 125 hours. Such certification does not grant
the purchaser, owner or operator of this engine any
additional warranties with respectto the performanceor
operational life of this engine.Theengine is warranted solely
according to the product and emissions warranties stated
elsewherein this manual.
Power Ratings
Thegross power rating for individual gas enginemodels is
labeled in accordancewith SAE(Society of Automotive
Engineers)codeJ1940 (Small Engine Power & Torque
Rating Procedure), and rating performance has been
obtained and corrected in accordancewith SAEJ1995
(Revision 2002-05). Torquevalues are derived at 3060 RPM;
horsepower values are derived at 3600 RPIVI.Actual gross
engine power will be lower and is affected by, among other
things, ambientoperating conditions and engine-to-engine
variability. Givenboth the wide arrayof products onwhich
enginesare placed andthe variety of environmental issues
applicableto operatingthe equipment,the gas engine will not
developthe ratedgross power when used in a given pieceof
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-enginevariability. Dueto
manufacturing and capacity limitations, Briggs & Stratton
may substitute an engine of higher ratedpower for this
Seriesengine.
This pressurewasher is rated in accordanceto the Pressure
Washer Manufacturer's Association (PWIVIA)standard
PW101 (Testingand Rating Performanceof Pressure
Washers).
