On Your

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 Air Index. The engine
manufacturer
makes
this
information
available
to the consumer
on 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 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.
