BRIGGS & STRATTON ENGINE OWNER WARRANTY POLICY

Effective September 1, 2006 

Briggs & Stratton Corporation will repair or replace, free of charge, any part(s) of the engine that is defective in material or workmanship or both.

Transportation charges on product submitted for repair or replacement under this warranty must be borne by purchaser. This warranty is effective

for and is subject to the time periods and conditions stated below. For warranty service, find the nearest Authorized Service Dealer in our

dealer locator map at www.briggsandstratton.com, or by calling (800) 233-3723, or as listed in the ‘Yellow Pages

’.

There is no other express warranty, implied warranties, including those of merchantability and fitness for a particular purpose, are

limited to one year from purchase, or to the extent permitted by law any and all implied warranties are excluded. Liability for incidental

or consequential damages are excluded to the extent exclusion is permitted by law.

 Some states or countries do not allow limitations on how

long an implied warranty lasts, and some states or countries do not allow the exclusion or limitation of incidental or consequential damages, so the

above limitation and exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights which vary

from state to state and country to country.

Engines used on Home Standby Generator applications are warranted under consumer use only.

 

This warranty does not

apply to engines on equipment used for prime power in place of a utility. 

Engines used in competitive racing or on

commercial or rental tracks are not warranted.

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. “Consumer use” means personal residential household use by a retail consumer. “Commercial use” means all other uses, including

use for commercial, income producing or rental purposes. Once an engine has experienced commercial use, it shall thereafter be considered as a

commercial use engine for purposes of this warranty.

No warranty registration is necessary to obtain warranty on Briggs & Stratton Products. 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.

ABOUT YOUR WARRANTY

Briggs & Stratton welcomes warranty repair and apologizes to you for being
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. 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 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.

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

Problems 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. (Use clean, fresh, lead-free
gasoline and Briggs & Stratton Fuel Stabilizer, Part No. 5041.)

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 oil level daily or after every 8 hours of operation. 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. Read
Operating & Maintenance Instructions.

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 re-oil the
Oil-Foam

 

element or the foam pre-cleaner, and replace the cartridge.) Read

Operating & Maintenance Instructions.

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
fins on the cylinder, cylinder head and flywheel at recommended intervals.)
Read Operating & Maintenance Instructions.

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.

Warranty service is available only through service dealers which have been
authorized by Briggs & Stratton Corporation. Your nearest Authorized Service
Dealer is listed in the “Yellow Pages

” of your telephone directory under

“Engines, Gasoline” or “Gasoline Engines,” “Lawn Mowers,” or similar
