Briggs & Stratton 28N700 Operating And Maintenance Instruction Manual page 17

About your engine warranty: (see next page for statement of LIMITED 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 dampge 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.
lf 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. lf 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 warrantv does not cover.
Normal wear:
Engines, like all mechanical devices, need periodic parts ser-
vice and replacement to perform well. Warranty will not cover
repair when normal use has exhausted the life of a part or an
engrne.
lmproper 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 dirly 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 vuhich the engine may be mounted.
Nor does the warranty extend to repairs required be-
cause of:
1. PROBLEMS CAUSED BY PARTS THAT ARE NOT
ORIGINAL BRIGGS & STRATTON PARTS.
2. Equipment controls or installations that prevent starting,
cause unsatisfactory engine pedormance, or shoften en-
gine 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, Parl No. 5041.)
4. Parts which are scored or broken because an engine was
ooerated with insufficient or contaminated lubricating oil,
or an incorrect grade of lubricating oil (check oil level daily
or after every 8 hours of operation. Re{ill when necessary
and change at recommended intervals.) OIL GARD@
may not shut down running engine. Engine damage may
ociur if oil level is not properly maintained. Read Operat-
ing & 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 re-
place the cartridge.) Read Operating & Maintenance
lnstructions.
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
lnstructions.
8. Engine or equipment parts broken by excessive vibration
caused by a loose engine mounting, loose cutler 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 ob-
iect with the cutter blade of a rotary lawn mower, or exces-
'sive
v-belt tightness.
10. Routine tune-up or adjustment of the engine.
