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 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 July 1,2000, Look For Emissions Compliance Period

On 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 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.

This is a generic representationof the emission label typically found on a certified engine.
