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 regarding the Emissions Durability Pe-
riod and the Air Index. Sears, Roebuck and Co., U.S.A. makes this information avail-
able 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 fol-
lowing 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 informa-
tion is displayed in graphical form on the emissions labe!.
After July 1, 2000, Look For Emissions Compliance
Period OnEngine 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 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 90000 is 148 cc.
The displacement engines of Model Series 120000 is 206 cc.
The displacement engines of Model Series 150000 is 249 cc.
The displacement engines of Model Series 200000 is 305 cc.
The displacement engines of Model Series 210000 is 342 cc.
This is a generic representation of the emission label
typically found on a certified engine.
