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 performance 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-en-
gine 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 conditions
(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.
GENERAL INFORMATION
This is a twin cylinder, overhead valve (OHV), air-cooled
engine. It is a low emissions engine.
In the state of California, Model 540000 and 610000
engines are certified by the California Air Resources Board
to meet emissions standards for 1000 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. This engine is warranted solely according to the
product and emissions warranties stated elsewhere in this
manual.

Note: For practical operation, the horsepower loading
should not exceed 85% of rated horsepower. 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 25 °.

SAFETY SPECIFICATIONS
• Read entire Operating & Maintenance Instructions
AND the instructions for the equipment this engine
powers.*
• Failure to follow instructions could result in serious
injury or death.
BEFORE OPERATING
ENGINE
* Briggs & Stratton does not necessarily know what equip-
ment 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.
• 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 OPERATING & MAINTENANCE
INSTRUCTIONS CONTAIN SAFETY
INFORMATION TO:
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 chemi-
cals known to the State of California to cause cancer,
birth defects, or other reproductive harm.

Starting engine creates sparking.
Sparking can ignite nearby flammable
gases.
Explosion and fire could result.
• If there is natural or LP gas leakage in area, do not
start engine.
• Do not use pressurized starting fluids because
vapors are flammable.
