GENERAC POWER SYSTEMS STANDARD TWO-YEAR LIMITED WARRANTY
FOR GENERAC STATIONARY EMERGENCY TRANSFER SWITCH SYSTEMS

NOTE: ALL UNITS MUST HAVE A START-UP INSPECTION PERFORMED BY AN AUTHORIZED GENERAC DEALER.

For a period of two (2) years or two thousand (2,000) hours of operation from the date of start-up, which ever occurs first, Generac Power Systems, 

Inc. will, at its option, repair or replace any part(s) which, upon examination, inspection, and testing by Generac Power Systems or an Authorized/

Certified Generac Power Systems Dealer, or branch thereof, is found to be defective under normal use and service, in accordance with the warranty 

schedule set forth below. Any equipment that the purchaser/owner claims to be defective must be examined by the nearest Authorized/Certified 

Generac Power Systems Dealer, or branch thereof. This warranty applies only to Generac Power Systems Transfer Switch used in "Stationary 

Emergency" applications, as Generac Power Systems, Inc. has defined Transfer Switch applications, provided said generator has been initially 

installed and/or inspected on-site by an Authorized/Certified Generac Power Systems Dealer, or branch thereof. Scheduled maintenance, as outlined 

by the generator owner's manual, must be performed by an Authorized/Certified Generac Power Systems Dealer, or branch thereof. This will verify 

service has been performed on the unit throughout the warranty period. This warranty is limited to and available only on Liquid-cooled units.

WARRANTY SCHEDULE

YEAR ONE — One hundred percent (100%) coverage on mileage, labor, and parts listed.

•  Any and all warranty repairs and/or concerns, must be performed and/or addressed by an Authorized/Certified Generac Power Systems Dealer, or 

branch thereof.

•  A Generac Power Systems, Inc. Transfer Switch is highly recommended to be used in conjunction with the generator set. If a Non-Generac Power 

Systems, Inc. Transfer Switch is substituted for use and directly causes damage to the generator set, no warranty coverage shall apply.

•  All warranty expense allowances are subject to the conditions defined in Generac Power Systems Warranty, Policies, Procedures and Flat Rate 

Manual.

•  Units that have been resold are not covered under the Generac Power Systems Warranty, as this Warranty is not transferable except with change 

of ownership of original structure.

• Unit enclosure is only covered during the first year of the warranty provision.

• Use of Non-Generac replacement part(s) will void the warranty in its entirety.

• Engine coolant heaters (block-heaters), heater controls and circulating pumps are only covered during the first year of the warranty provision.

  1.  Any unit built/manufactured prior to July 1, 2004.

  2.  Costs of normal maintenance (i.e. tune-ups, associated part(s), adjustments, loose/leaking clamps, installation and start-up).

  6.  Products that are modified or altered in a manner not authorized by Generac Power Systems in writing.

  7.  Failures due, but not limited to, normal wear and tear, accident, misuse, abuse, negligence, or improper installation or sizing.

 15.   Steel enclosures that are rusting due to improper installation, location in a harsh or saltwater environment or scratched where integrity of paint 

applied is compromised.

cause of the problem.

 17.  Starting batteries, fuses, light bulbs, engine fluids, and overnight freight cost for replacement part(s).

OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Any implied warranties which are allowed by
