Craftsman 580.754890 Operator's Manual page 33

The warranty on emissions-related parts is as follows:
• Any warranted part that is not scheduled for
replacement as required maintenance in the Operator's
Manual supplied, is warranted for the warranty period
stated above. If any such part fails during the period
of warranty coverage, the part will be repaired or
replaced by Sears at no charge to the owner. Any such
part repaired or replaced under the warranty will be
warranted for the remaining warranty period.
Any warranted part that is scheduled only for regular
inspection in the Operator's Manual supplied, is
warranted for the warranty period stated above. Any
such part repaired or replaced under warranty will be
warranted for the remaining warranty period.
• Any warranted part that is scheduled for replacement
as required maintenance in the Operator's Manual
supplied, is warranted for the period of time prior to the
first scheduled replacement point for that part. If the
part fails prior to the first scheduled replacement, the
part will be repaired or replaced by Sears at no charge
to the owner. Any such part repaired or replaced under
warranty will be warranted for the remainder of the
period prior to the first scheduled replacement point for
the part.
Add-on or modified parts that are not exempted by the
Air Resources Board may not be used. The use of any
non-exempted add-on or modified parts by the owner
will be grounds for disallowing a warranty claim. The
manufacturer will not be liable to warrant failures of
warranted parts caused by the use of a non-exempted
add-on or modified part.
3. Consequential Coverage
Coverage shall extend to the failure of any engine
components caused by the failure of any warranted
emissions parts.
4. Claims and Coverage Exclusions
Warranty claims shall be filed according to the
provisions of the Sears engine warranty policy. Warranty
coverage does not apply to failures of emissions parts
that are not original equipment Sears parts or to parts
that fail due to abuse, neglect, or improper maintenance
as set forth in the Sears engine warranty policy. Sears is
not liable for warranty coverage of failures of emissions
parts caused by the use of add-on or modified parts.
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 Period
and the Air Index. Briggs & Stratton makes this information
available to the 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 Operator's Manual. The following
categories are used:
Moderate: Engines at or less than 80 cc displacement are
certified to be emissions compliant for 50 hours of actual
engine running time. Engines greater than 80 cc displacement
are certified to be emissions compliant for 125 hours of actual
engine running time.
Intermediate: Engines at or less than 80 cc displacement
are certified to be emissions compliant for 125 hours of actual
engine running time. Engines greater than 80 cc displacement
are certified to be emissions compliant for 250 hours of actual
engine running time.
Extended: Engines at or less than 80 cc displacement are
certified to be emissions compliant for 300 hours of actual
engine running time. Engines greater than 80 cc displacement
are 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.
Engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 or Phase 3 emissions
standards. 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 at or less than 80 cc displacement:
Category C = 50 hours, Category B = 125 hours, Category A
= 300 hours
For engines greater than 80 cc displacement and less than
225 cc displacement:
Category C = 125 hours, Category B = 250 hours, Category A
= 5OOhours
For engines of 225 cc or more displacement:
Category C = 250 hours, Category B = 500 hours, Category A
= 1000 hours
