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, Model Series 50000, 85400,
86400, 117400, 118400, 138400 engines are certified

sions standards for 125 hours; Model Series, 185400,
235400, 245400, 246400 for 250 hours. Such certifica-
tion 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.

The safety alert symbol is used to identify safety
information about hazards that can result in personal injury.
A signal word (DANGER, WARNING, or CAUTION) is used
with the alert symbol to indicate the likelihood and the potential
severity of injury. In addition, a hazard symbol may be used to
represent the type of hazard.
DANGER indicates a hazard which, if not avoided,
will result in death or serious injury.
WARNING indicates a hazard which, if not avoided,
could result in death or serious injury.
CAUTION indicates a hazard which, if not avoided,
