          Subpart B_Emission Standards and Related Requirements
 
Sec.  1048.120  What emission-related warranty requirements apply to me?

    (a) General requirements. You must warrant to the ultimate purchaser 
and each subsequent purchaser that the new nonroad engine, including all 
parts of its emission-control system, meets two conditions:
    (1) It is designed, built, and equipped so it conforms at the time 
of sale to the ultimate purchaser with the requirements of this part.
    (2) It is free from defects in materials and workmanship that may 
keep it from meeting these requirements.
    (b) Warranty period. Your emission-related warranty must be valid 
for at least 50 percent of the engine's useful life in hours of 
operation or at least three years, whichever comes first. In the case of 
a high-cost warranted part, the warranty must be valid for at least 70 
percent of the engine's useful life in hours of operation or at least 
five years, whichever comes first. You may offer an emission-related 
warranty more generous than we require. The emission-related warranty 
for the engine may not be shorter than any published warranty you offer 
without charge for the engine. Similarly, the emission-related warranty 
for any component may not be shorter than any published warranty you 
offer without charge for that component. If an engine has no hour meter, 
we base the warranty periods in this paragraph (b) only on the engine's 
age (in years). The warranty period begins when the engine is placed 
into service.
    (c) Components covered. The emission-related warranty covers all 
components whose failure would increase an engine's emissions of any 
pollutant. This includes components listed in 40 CFR part 1068, Appendix 
I, and components from any other system you develop to control 
emissions. The emission-related warranty covers these components even if 
another company produces the component. Your emission-related warranty 
does not cover components whose failure would not increase an engine's 
emissions of any pollutant.
    (d) Limited applicability. You may deny warranty claims under this 
section if the operator caused the problem through improper maintenance 
or use, as described in 40 CFR 1068.115.
    (e) Owners manual. Describe in the owners manual the emission-
related warranty provisions from this section that apply to the engine.
