Note: (This note applies only to engines used in the U.S.A.) Maintenance, replacement or repair of the emission control devices and systems may be performed
by any nonroad engine repair establishment or individual. However, to obtain no charge repairs under the terms and provisions of the Briggs & Stratton
warranty statement, any service or emission control part repair or replacement must be performed by a factory authorized dealer.

In the state of California, OHV Model 400000 and
440000 engines are certified by the California Air
Resources Board to meet emissions standards for 250
hours. Such certification does not grant the purchaser,
owner or operator of this engine any additional
warranties with respect to the performance or opera‐
tional life of this engine. This engine is warranted solely
according to the product and emissions warranties
stated elsewhere in this manual.
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.

Safety Precautions
• 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.
* 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.
THE OPERATING & MAINTENANCE
INSTRUCTIONS 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,

the engine.
WARNING
The engine exhaust from this product contains
chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
WARNING
Gasoline and its vapors are extremely flammable
and explosive.
Fire or explosion can cause severe burns or death.
WHEN ADDING FUEL
• Turn engine OFF and let engine cool at least 2
minutes before removing gas cap.
• Fill fuel tank outdoors or in well‐ventilated area.
• Do not overfill fuel tank. Fill tank to approximately
1‐1/2 inches below top of neck to allow for fuel
expansion.
• Keep gasoline away from sparks, open flames, pilot
lights, heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently
for cracks or leaks. Replace if necessary.
WHEN STARTING ENGINE
• Make sure spark plug, muffler, fuel cap and air
cleaner are in place.
• Do not crank engine with spark plug removed.
• If fuel spills, wait until it evaporates before starting
engine.
• If engine floods, set choke to OPEN/RUN position,
place throttle in FAST and crank until engine starts.
WHEN OPERATING EQUIPMENT
• Do not tip engine or equipment at angle which
causes gasoline to spill.
• Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY or with fuel shut‐off
valve OFF.
WHEN STORING GASOLINE OR EQUIPMENT WITH
FUEL IN TANK
• Store away from furnaces, stoves, water heaters or
other appliances that have pilot light or other ignition
source because they can ignite gasoline vapors.
