General Information

This manual contains safety information to make you aware of the hazards and risks
associated with engines and how to avoid them. It also contains instructions for the
proper use and care of the engine. Because Briggs & Stratton Corporation does not
necessarily know what equipment this engine will power, it is important that you read and
understand these instructions and the instructions for the equipment. Save these
original instructions for future reference.
For replacement parts or technical assistance, record below the engine model, type, and
code numbers along with the date of purchase. These numbers are located on your
engine (see the Features and Controls page).

Power Rating

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. Net power values are taken with
exhaust and air cleaner installed whereas gross power values are collected without
these attachments. Actual gross engine power will be higher than net engine power and
is affected by, among other things, ambient operating conditions and engine--to--engine
variability. Given the wide array of products on which engines are placed, the gas engine
may not develop the rated gross power when used in a given piece of power equipment.
This difference is due to a variety of factors including, but not limited to, the variety of
engine components (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.

under warranty.
WARNING
Fuel 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 the fuel
•
cap.
Fill fuel tank outdoors or in well-ventilated area.
•
Do not overfill fuel tank. To allow for expansion of the fuel, do not fill above the
•
bottom of the fuel tank neck.
Keep fuel 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
Slow If fuel spills, wait until it evaporates before starting engine.
•
When Starting Engine
Ensure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in
•
place and secured.
Fuel Do not crank engine with spark plug removed.
•
If engine floods, set choke (if equipped) to OPEN/RUN position, move throttle
•
(if equipped) to FAST position and crank until engine starts.
When Operating Equipment
Wear Eye
Do not tip engine or equipment at angle which causes fuel to spill.
•
Protection
Do not choke the carburetor to stop engine.
•
Never start or run the engine with the air cleaner assembly (if equipped) or the
•
air filter (if equipped) removed.
When Changing Oil
When you drain the oil from the top oil fill tube, the fuel tank must be empty or
•
fuel can leak out and result in a fire or explosion.
When Transporting Equipment
Transport with fuel tank EMPTY or with fuel shut-off valve OFF.
•
When Storing Fuel Or Equipment With Fuel In Tank
Store away from furnaces, stoves, water heaters or other appliances that have
•
pilot lights or other ignition sources because they can ignite fuel vapors.
WARNING
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.
