* Natural gas rating will depend on specific fuel but typical derating of generator is between
10 to 20% off the LP gas rating. 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 necessarily match the values derived using
the foregoing codes.

NOTE: For practical operation, the generator load should
not exceed 85% of rated wattage. 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). Engine will operate satisfactorily at an angle up to
15°.
