Look For Relevant Emissions E)urabiHty Period and
Air hde× mnformation On Your Engine Emissions Labe_
Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emission Standards must
display information regarding 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 & Mainte-
nance 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 engine 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.
After Ju_y 1,2000, Look For Emissions Compliance Period
On Engine Emissions Compliance Labe_
After July 1, 2000 certain Sears, Roebuck and Co., U.SoA. engines will be certified to meet the United States
Environmental Protection Agency (USEPA) Phase 2 emission standards. For Phase 2 certified engines, the Emis-
sions 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 emission requirements.
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.
The displacement engines of Model Series 150112 is 249 cc.
This isa generic representation of the emission labeltypically found on a certified engine.
