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
2002Ć05). 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 equipĆ
ment (actual onĆsite" 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 runĆin 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 foregoing codes.
GENERAL INFORMATION
This is a twin cylinder, overhead valve (OHV), airĆcooled
engine. It is a low emissions engine.
In the state of California, Model Series 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.

Displacement 895 cc (54.6 cu. in.) . . . . . . . . . . . . . . .
Note: For practical operation, the horsepower loading
should not exceed 85% of rated horsepower. Engine power will
decrease 3Ć1/2% 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 equipĆ
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 chemiĆ
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.
