Note: (This note applies only to engines used in the U.S.A.) Maintenance, replacement or repair of the emission control devices and systems may be performed
by any nonroad engine repair establishment or individual. However, to obtain no charge repairs under the terms and provisions of the Briggs & Stratton
warranty statement, any service or emission control part repair or replacement must be performed by a factory authorized dealer.

TECHNICAL INFORMATION
Power Ratings
The power ratings for an individual engine model are initially
developed by starting with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating
Procedure) (Revision 2002 05). Given both the wide array of
products on which our engines are placed, and the variety of
environmental issues applicable to operating the equipment, it
may be that the engine you have purchased will not develop
the rated horsepower when used in a piece of power
equipment (actual on site" power). This difference is due to a
variety of factors including, but not limited to, the following:
differences in altitude, temperature, barometric pressure,
humidity, fuel, engine lubrication, maximum governed engine
speed, individual engine to engine variability, design of the
particular piece of power equipment, the manner in which the
engine is operated, engine run in to reduce friction and clean
out of combustion chambers, adjustments to the valves and
carburetor, and other factors. The power ratings may also be
adjusted based on comparisons to other similar engines
utilized in similar applications, and will therefore not necessari
ly match the values derived using the foregoing codes.
GENERAL INFORMATION
In the state of California, OHV Model Series 110000 and
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. This engine is
warranted solely according to the product and emissions
warranties stated elsewhere in this manual.
