3 The following categories areused:Moderate:Engine is certified to be emission compliant for 50 hours of actual engine running :Engine is certified to be emission compliant for 125 hours of actual engine running :Engine is certified to be emission compliant for 300 hours of actual engine running example, a typical consumer string trimmer is used 5 to 10 hours per year. Therefore, theEmissions Durability Periodof anenginewith anmoderaterating would equate to 5 to 6 Indexis a calculated number describing the relative level of emissions for a specific engine family. The lower theAir Index,thecleaner the engine.

For Phase 2 Class IVcertified engines,the EmissionsCompliance Periodreferred toon theEmis-sions Compliance label indicates the number of Operating hours for which the engine hasbeen shownto meetFederal emissionrequire-ments. For engines equal to or greater than 20 cc, and less than 50 cc displacement, Category C = 50 hours, B = 125 hours and A =300 displacement of Model Series 21000 engines is 34 cc, 21100 engines is 40 is a generic representationof the emission label typicallyfound on a certified Operating ENGINE Read entire Operating & Maintenance Instructions ANDthe Instructions for the equipment this engine powers.
