SPECIFICATIONS
Model 074002 air compressors are powered by a single
cylinder, overhead valve (OHV), air cooled, low emissions
engine.
In the State of California, these air compressor engines are
certified by the California Air Resources Board to meet
emissions standards for 250 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 as
stated on pages 26 and 27.
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 necessarily match the
values derived using the above listed codes.
