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.

label indicates
the number
of operating
hours for which the engine has been shown to meet Federal

or more, Category
C = 250 hours,
B = 500 hours
and A = 1000 hours.
