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
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.

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-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 conditions
(temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing
power for this Series engine.

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.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum
deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh,
®fuel stabilizer, available as a liquid additive or a
drip concentrate cartridge.
There is no need to drain gasoline from the engine if a fuel stabilizer is added according
to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel
system. The engine and fuel can then be stored up to 24 months.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into
an approved container. Run the engine until it stops from lack of fuel. The use of a fuel
stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil.
NOTICE: Store the engine level (normal operating position). If the engine is tipped for
storage, the fuel tank must be empty and the spark plug side must be up. If the fuel

About Your Warranty
inconvenienced. Any Authorized Service Dealer may perform warranty repairs. Most
warranty repairs are handled routinely, but sometimes requests for warranty service may
not be appropriate.
If a customer differs with the decision of the Service Dealer, an investigation will be made
to determine whether the warranty applies. Ask the Service Dealer to submit all
supporting facts to his Distributor or the Factory for review. If the Distributor or the
Factory decides that the claim is justified, the customer will be fully reimbursed for those
items that are defective. To avoid misunderstanding which might occur between the
customer and the Dealer, listed below are some of the causes of engine failure that the
warranty does not cover.
Normal wear: Engines, like all mechanical devices, need periodic parts service and
replacement to perform well. Warranty will not cover repair when normal use has
exhausted the life of a part or an engine. Warranty would not apply if engine damage
occurred because of misuse, lack of routine maintenance, shipping, handling,
warehousing or improper installation. Similarly, warranty is void if the serial number of the
engine has been removed or the engine has been altered or modified.
Improper maintenance: The life of an engine depends upon the conditions under which
it operates, and the care it receives. Some applications, such as tillers, pumps and rotary
mowers, are very often used in dusty or dirty conditions, which can cause what appears
to be premature wear. Such wear, when caused by dirt, dust, spark plug cleaning grit, or
other abrasive material that has entered the engine because of improper maintenance, is
not covered by warranty.
This warranty covers engine related defective material and/or workmanship only,
and not replacement or refund of the equipment to which the engine may be
mounted. Nor does the warranty extend to repairs required because of:
1Problems caused by parts that are not original Briggs & Stratton parts.
2 Equipment controls or installations that prevent starting, cause unsatisfactory engine
performance, or shorten engine life. (Contact equipment manufacturer.)
3 Leaking carburetors, clogged fuel pipes, sticking valves, or other damage, caused
by using contaminated or stale fuel.
4 Parts which are scored or broken because an engine was operated with insufficient
or contaminated lubricating oil, or an incorrect grade of lubricating oil (check and
refill when necessary, and change at recommended intervals). OIL GARD may not
shut down running engine. Engine damage may occur if oil level is not properly
maintained.
5 Repair or adjustment of associated parts or assemblies such as clutches,
transmissions, remote controls, etc., which are not manufactured by Briggs &
Stratton.
6 Damage or wear to parts caused by dirt, which entered the engine because of
improper air cleaner maintenance, re-assembly, or use of a non-original air cleaner
element or cartridge. At recommended intervals, clean and/or replace the filter as
stated in the Operator’s Manual.
7 Parts damaged by over-speeding, or overheating caused by grass, debris, or dirt,
which plugs or clogs the cooling fins, or flywheel area, or damage caused by
operating the engine in a confined area without sufficient ventilation. Clean engine
debris at recommended intervals as stated in the Operator’s Manual.
8 Engine or equipment parts broken by excessive vibration caused by a loose engine
mounting, loose cutter blades, unbalanced blades or loose or unbalanced impellers,
improper attachment of equipment to engine crankshaft, over-speeding or other
abuse in operation.
9 A bent or broken crankshaft, caused by striking a solid object with the cutter blade of
a rotary lawn mower, or excessive v-belt tightness.
10 Routine tune-up or adjustment of the engine.
11 Engine or engine component failure, i.e., combustion chamber, valves, valve seats,
valve guides, or burned starter motor windings, caused by the use of alternate fuels
such as, liquified petroleum, natural gas, altered gasolines, etc.

Look For Relevant Emissions Durability Period and Air Index Information
On Your Small Off-Road Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) small
off-road Emissions Standard must display information regarding the Emissions Durability
consumer on our emissions labels. The engine emissions label will indicate certification
information.
The Emissions Durability Period describes the number of hours of actual running time
for which the engine is certified to be emissions compliant, assuming proper
maintenance in accordance with the Operating & Maintenance Instructions. The
following categories are used:
Moderate:
Engine is certified to be emissions compliant for 125 hours of actual engine running time.
Intermediate:
Engine is certified to be emissions compliant for 250 hours of actual engine running time.
Extended:
Engine is certified to be emissions compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, the Emissions Durability Period of an engine with an intermediate rating
would equate to 10 to 12 years.
Protection Agency (USEPA) Phase 2 emissions standards. For Phase 2 certified
engines, the Emissions Compliance Period referred to on the Emissions Compliance
label indicates the number of operating hours for which the engine has been shown to
meet Federal emissions requirements.
For engines less than 225 cc displacement.
Category C = 125 hours, Category B = 250 hours, Category A = 500 hours
For engines of 225 cc or more displacement.
Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours
