Power Ratings: The power ratings for an individual engine mod-
el are initially developed by starting with SAE (Society of Automo-
tive 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 (ac-
tual "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 lubrica-
tion, maximum governed engine speed, individual engine to en-
gine variability, design of the particular piece of power equipment,
the manner in which the engine is operated, engine run-in to re-
duce 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 en-
gines utilized in similar applications, and will therefore not neces-
sarily match the values derived using the foregoing codes.
NOTE: Actual sustained horsepower will likely be lower due
to operating limitations and environmental factors.

REPAIR PROTECTION AGREEMENT
A Repair Protection Agreement is available on this unit. See the
nearest Sears Store for information.
Engine Exhaust, some of its constituents, and
certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other repro-
ductive harm.
Battery posts, terminals and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the State of California to cause
cancer and birth defects or other reproductive
harm. WASH HANDS AFTER HANDLING.
NOTE: This unit is equipped with an internal combustion engine
and must not be used on or near any unimproved forest-covered,
brush-covered or grass-covered land unless the engine's exhaust
system is equipped with a spark arrester meeting applicable local
or state laws (if any). If a spark arrester is used, it must be
maintained in effective working order by the operator.
In the State of California, the above is required by law (Section
4442 of the California Public Resources Code). Other states may
have similar laws. Federal laws apply on federal lands. See a
Sears Service Center for a spark arrester for the muffler.
In some areas, local law requires the use of a resistor spark plug
to control the ignition signals. See a Sears Service Center for a
resistor spark plug for the engine.
In the state of California, Model Series 280000 engines are certi-
fied 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 war-
ranties 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.
