Limited Warranty
Off-road Diesel Engines

The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Kohler Co. are pleased to explain the Federal and California Emission Control System Warranty on your [current year – following year]* off-road compression ignition (diesel) engine. Kohler Co. warrants that the engine is designed, built and equipped to meet the U.S. EPA and CARB off-road diesel regulations. The warranty period shall begin on the date the engine or equipment is delivered to an ultimate purchaser. The engine must be free of material or workmanship defects for the time period detailed in the manufacturer’s warranty coverage section of this document below. Kohler Co. must warrant the emission control system on the engine for the period of time listed in the section below, provided there has been no abuse, neglect or improper maintenance.

The owner shall not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective, provided that such diagnostic work is performed at a warranty station.

MANUFACTURER’S WARRANTY COVERAGE
Your off-road, diesel engine emission control system is covered under warranty for a period of five (5) years or 3,000 hours, whichever occurs first, beginning on the date the engine or equipment is delivered to an ultimate purchaser for all constant speed engines with maximum power 19≤kW<37 and rated speed less than 3,000 rpm, all variable speed engines with maximum power 19≤kW<37, and all variable or constant speed engines with maximum power greater than 37 kW.

OWNER’S WARRANTY RESPONSIBILITIES
(a) You are responsible for the performance of all required maintenance including the use of approved fluids as detailed in your operators/ owners manual. It is not necessary for replacement parts to be the same brand or by the same manufacturer as the original part sold with the engine. Such use shall not reduce the warranty obligations of the engine manufacturer.
(b) Be aware, however, that Kohler Co. may deny warranty coverage if the engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.
(c) You are responsible for initiating the warranty process. The ARB suggests that you present your heavy-duty off-road engine to a Kohler dealer as soon as a problem exists. Call 1-800-544-2444 or access our website at www.kohlerengines.com, for the names of the nearest service centers.


COVERAGE
Kohler Co. will repair or replace emission control system parts, components and sub-assemblies found to be defective with respect to materials or workmanship at no cost to you including engine exhaust system related diagnosis, labor and parts. The choice and responsibility of the decision to repair or replace an emission control system defect will be solely that of Kohler Co. Emission control system parts/ components covered by the Federal and California Emission Control Systems Limited Warranty are listed below.

• Fuel injector(s)
• Injection pump(s)
• Exhaust manifold
• Intake manifold
• Exhaust gas recirculation (EGR) tube
• Crankcase ventilation valve
• Electronic control unit (ECU) if equipped
• Sensors associated with ECU operation
• Emission control information labels
• Turbocharger (if equipped)
• Fuel limiting device



Parts/ components that are scheduled to be replaced as part of the required maintenance schedule will be covered under the warranty provisions for a period of time up to the first scheduled replacement point for the subject parts/ components. Subsequent damage to other engine components as a direct result of a warrantable failure an exhaust emission part/ component will be covered under the warranty provisions described herein.

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.
