To register your warranty, have one of our authorized service technicians complete a post-installation Warranty Start-Up at your home. Then, instead of your warranty beginning on the day the generator is purchased, it begins on the day your service technician submits your generator system's details to the Warranty Start-Up program. The technician completes a checklist, makes sure the system is properly installed, and enters all necessary information onto the Kohler Warranty site. This moves the warranty start date to the day your generator is installed, instead of the date it left the factory.
