Look For Relevant Emissions
Durability Period and
Air Index Information
On Your Engine Emissions
Label
Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emission Standards must display information regard-
ing the Emissions Durability Period and the Air Index. Sears, Roebuck and Co., U.S.A. makes this information available to the consumer
on our emission labels.
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 Operating & Maintenance Instructions. The following categories are
used:
Moderate:
Engine is certified to be emission compliant for 125 hours of actual engine running time.
Intermediate:
Engine is certified to be emission compliant for 250 hours of actual engine running time.
Extended:
Engine is certified to be emission 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 en-
gine with an intermediate
rating would equate to 10 to 12 years.
The Air Index is a calculated number describing the relative level of emissions for a specific engine family. The lower the Air Index, the
cleaner the engine. This information is displayed in graphical form on the emissions label.

Engine Emissions
Compliance
Label
After July 1,2000 certain Sears, Roebuck and Co., U.S.A. engines will be certified to meet the United States Environmental Protection
Agency (USEPA) Phase 2 emission standards. For Phase 2 certified engines, the Emissions Compliance Period referred to on the Emis-
sions Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emission require-
ments. For engines less than 225 cc displacement, Category C = 125 hours, B = 250 hours and A = 500 hours. For engines of 225 cc
or more, Category C = 250 hours, B = 500 hours and A = 1000 hours.
