About your engine 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 gasoline 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.) Read “Owner’s Manuals”.
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 overspeeding, 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, im-proper attachment of
equipment to engine crankshaft, overspeeding 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
exces-sive 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.
