Note the following special warranty periods: 

For purposes of this warranty policy, Parts and Labor coverage is 2 years. Major parts only

coverage is extended to through the third year of operation. 

Major Parts Warranty (M.P.W.) covers

 but is not limited to or exclusive to cylinder

block, cylinder head, crankshaft, camshaft, gears, pistons, rods, flywheel, flywheel housing, oil pump, fan, pulleys, mechanical governor,
intake manifold, oil pan. 

M.P.W. does not cover

 and is not limited to piston rings, replaceable bearings, water pump, any electrical component,

valve train components, accessory parts, seals, gaskets, carburetors, exhaust manifold, hoses, all fuel system components, injectors,
injection pump, turbocharger, muffler, any filters, radiator, thermostat, spark plugs, glow plugs, fuel transfer pumps. The warranty period begins
on the date of purchase by the first retail consumer or commercial end user, and continues for the period of time stated in the table above.

NO WARRANTY REGISTRATION IS NECESSARY TO OBTAIN WARRANTY ON B&S ENGINES. SAVE YOUR PROOF OF PURCHASE
RECEIPT. IF YOU DO NOT PROVIDE PROOF OF THE INITIAL PURCHASE DATE AT THE TIME WARRANTY SERVICE IS REQUESTED,
THE MANUFACTURING DATE OF THE PRODUCT WILL BE USED TO DETERMINE THE WARRANTY PERIOD.

B&S welcomes warranty repair and apologizes to you for being
inconvenienced. Any Authorized Briggs & Stratton 3/LC Service
Dealer may perform warranty repairs. Most warranty repairs are
handled routinely, but sometimes requests for warranty service
may not be appropriate. For example, 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.
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
the 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.

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:

1.

Engines that are not properly applied to equipment. It is
strongly recommended that the factory be contacted prior
to applying a B&S 3/LC engine to equipment that did not
originally use a B&S 3/LC engine.

2.

PROBLEMS CAUSED BY PARTS THAT ARE NOT
ORIGINAL BRIGGS & STRATTON PARTS.

3.

Equipment controls or installations that prevent starting,
cause unsatisfactory engine performance, or shorten
engine life. (Contact equipment manufacturer.)

4.

Leaking carburetors, clogged fuel pipes or injectors,
sticking valves, contaminated injection pumps, or other
damage, caused by using contaminated or stale fuel. Use
clean, fresh fuel (lead free gasoline, diesel fuel) and Briggs
& Stratton fuel stabilizer, Part No. 5041.

5.

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 oil level daily
or after every 8 hours of operation. Refill when necessary
and change oil and oil filter at recommended intervals.)
OIL GARD may not shut down running engine. Engine
damage may occur if oil level is not properly maintained.
Read Operating & Maintenance Instructions.

6.

Repair or adjustment of associated parts or assemblies
such as clutches, transmissions, remote controls, etc.,
which are not manufactured by B&S.

7.

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, replace
cartridge.) Read Operating & Maintenance Instructions.

8.

Parts damaged by over-speeding, or overheating caused
by grass, debris, or dirt, which plugs, clogs radiator or air
cooling access openings, or damage caused by operating
the engine in a confined area without sufficient ventilation.
Engine damage caused by not using accurate mix of
anti-freeze and tap water, or water entering the engine due
to any cause.

9.

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.

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.

Warranty is available only through service dealers which
have been authorized by Briggs & Stratton. Locate your
nearest Authorized B&S 3/LC Service Dealer through our
dealer locater map on www.briggsandstratton.com.
