TECHNICAL INFORMATION
Engine Power Rating Information
The gross power rating for individual gas engine
models is labeled in accordance with SAE (Society of
Automotive Engineers) code J1940 (Small Engine
Power & Torque Rating Procedure), and rating perfor-
mance has been obtained and corrected in accordance
with SAE J1995 (Revision 2002-05). Torque values are
derived at 3060 RPM; horsepower values are derived
at 3600 RPM. Actual gross engine power will be lower
and is affected by, among other things, ambient
operating conditions and engine-to-engine variability.
Given both the wide array of products on which engines
are placed and the variety of environmental issues
applicable to operating the equipment, the gas engine
will not develop the rated gross power when used in a
given piece of power equipment (actual on-site" or net
power). This difference is due to a variety of factors
including, but not limited to, accessories (air cleaner,
exhaust, charging, cooling, carburetor, fuel pump,
etc.), application limitations, ambient operating condi-
tions (temperature, humidity, altitude), and engine-to-
engine variability. Due to manufacturing and capacity
limitations, Briggs & Stratton may substitute an engine
of higher rated power for this Series engine.

tional life of this engine. This engine is warranted solely
according to the product and emissions warranties
stated elsewhere in this manual.
SAFETY SPECIFICATIONS
* Briggs & Stratton does not necessarily know what
equipment this engine will power. For that reason,
you should carefully read and understand the
operating instructions for the equipment on which
your engine is placed.
BEFORE OPERATING ENGINE
• Read entire Operator’s Manual AND the
instructions for the equipment this engine
powers.*
• Failure to follow instructions could result in
serious injury or death.
THE OPERATOR’S MANUAL CONTAIN SAFETY
INFORMATION TO
• Make you aware of hazards associated with
engines
• Inform you of the risk of injury associated with
those hazards, and
• Tell you how to avoid or reduce the risk of injury.
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, might result in minor or moderate
injury.
CAUTION, when used without the alert
symbol, indicates a situation that could result
in damage to the engine.
The engine exhaust from this product contains
chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
WARNING
Briggs & Stratton does not approve or authorize
the use of these engines on 3-wheel All Terrain
Vehicles (ATVs), motor bikes, fun/recreational
go-karts, aircraft products or vehicles intended for
use in competitive events. Use of these engines in
such applications could result in property damage,
serious injury (including paralysis), or even death.
