Warranty

EMISSION CONTROL SYSTEM WARRANTY

Exhaust Emission Control System Warranty (ECS Warranty) for equipment using small spark-ignited engines:
(a)   Applicability: This warranty shall apply to equipment that uses small off-road engines. The ECS Warranty period shall begin on the date the new 

equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue for the lesser of:

 

(1)  The period of time specified in the product Warranty enclosed herewith, but not less than 24 months, or

 

(2)   For engines equipped with hour meters, a number of operating hours equal to half of the engine’s useful life. The useful life is specified on the 

Emissions Control Label on the engine.

(b)   General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or equipment and to each 

subsequent purchaser/owner that the ECS when installed was:

 

(1)  Designed, built and equipped so as to conform with all applicable regulations; and

 

(2)  Free from defects in materials and workmanship which cause the failure of a warranted part at any time during the ECS Warranty Period.

(c)  The warranty on exhaust emissions-related parts will be interpreted as follows:
 

(1)   Any warranted part that is not scheduled for replacement as required maintenance in the Owner's Manual shall be warranted for the ECS 

Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by Generac according to Subsection 
(4) below. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.

 

(2)   Any warranted part that is scheduled only for regular inspection as specified in the Owner's Manual shall be warranted for the ECS Warranty 

Period. A statement in the Owner’s Manual to the effect of "repair or replace as necessary" shall not reduce the ECS Warranty Period. Any 
such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.

 

(3)   Any warranted part that is scheduled for replacement as required maintenance in the Owner's Manual shall be warranted for the period of time 

prior to first scheduled replacement point for that part. If the part fails prior to the first scheduled replacement, the part shall be repaired or 
replaced by Generac according to Subsection (4) below. Any such exhaust emissions-related part repaired or replaced under the ECS war-
ranty shall be warranted for the remainder of the period prior to the first scheduled replacement point for that part.

 

(4)   Repair or replacement of any warranted, exhaust emissions-related part under this ECS Warranty shall be performed at no charge to the 

owner at a Generac Authorized Warranty Service Facility.

 

(5)   Notwithstanding the provisions of subsection (4) above, warranty services or repairs must be provided at Generac Authorized Service 

Facilities.

 

(6)   When the engine is inspected by a Generac Authorized Warranty Service Facility, the purchaser/owner shall not be held responsible for diag-

nostic costs if the repair is deemed warrantable.

 

(7)   Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted exhaust emission-related parts sufficient to meet the 

expected demand for such parts.

 

(8)   Any Generac authorized and approved replacement parts may be used in the performance of any ECS Warranty maintenance or repairs and 

will be provided without charge to the purchaser/owner. Such use shall not reduce Generac ECS Warranty obligations.

 

(9)   No modifications, other than those explicitly approved by Generac, may be made to the equipment. Unapproved modifications void this ECS 

Warranty and shall be sufficient ground for disallowing an ECS Warranty claim.

 

(10)   Generac shall not be held liable hereunder for failures of any non-authorized replacement parts, or failures of any authorized parts caused by 

the use of non-authorized replacement parts.
