Look For Relevant Emissions Durability Period and Air
Index Information On Your Engine Emissions Label
Engines that are certifiedto meet the California Air Resources Board (CARB) "her2
Emission Standards mustdisplay informationregarding the Emissions Durability Pe-
riod and theAir Index. Sears, Roebuck and Co., U.S.A. makes this informationavail-
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 certifiedto be emissioncompliant for 125 hours of actual
engine running time.
Intermediate: Engine is certifiedto be emissioncompliant for 250 hoursof actual
engine runningtime.
Extended: Engine is certifiedto be emissioncompiient for 500 hoursof actual
engine runningtime.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, the Emissions Durability Period of an engine w_ an intermediate
rating would equate to 10 to 12 years.
The Air Index is a calculated number describing the relative level ofemissions 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 label.
