As the heavy-duty off-road engine owner, you should however be aware that Kohler may deny you warranty coverage if your heavy-duty off-road engine or a part
has failed due to abuse, neglect, improper maintenance or unapproved modifications. Only due to the above reasons, the manufacturer may deny the warranty
coverage.
MAINTENANCE AND REPAIR REQUIREMENTS
The owner is responsible for the proper use and maintenance of the engine. Kohler Co. recommends that all receipts and records covering the performance of
regular maintenance be retained in case questions arise. If the engine is resold during the warranty period, the maintenance records should be transferred to each
subsequent owner. Kohler Co. may not deny warranty repairs solely because of the lack of repair, maintenance or failure to keep maintenance records.
Normal maintenance, replacement or repair of emission control devices and systems may be performed by any repair establishment or individual; however,
warranty repairs must be performed by a Kohler authorized service center. Any replacement part or service that is equivalent in performance and durability
may be used in non-warranty maintenance and repairs, and shall not reduce the warranty obligations of the engine manufacturer.
