Pe-
riod and the Air Index. Sears,

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 label.

For Phase 2 certified

the Emissions

label indicates
the number of operating
hours for which the
engine has been shown to meet Federal emission
requirements.
For engines

B = 250 hours and A = 500 hours. For
engines
of 225 cc or more, Category
