CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board
and Kohler Co. are pleased to explain the
emission control system warranty
on your 2012 engine. In
California, new heavy-duty off-road engines must be designed, built and equipped to meet the State’s stringent anti-smog standards. Kohler Co.
must warrant the emission control system on your engine for the time period listed below provided there has been no abuse, neglect or improper
maintenance of your engine.
Your emission control system may include parts such as the fuel-injection system and the air induction system. Also included may be hoses,
connectors and other emission related assemblies.
Where a warrantable condition exists, Kohler Co. will repair your heavy-duty off-road engine at no cost to you including diagnosis, parts and labor.
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. Your off-road, diesel engine emission control system on variable or constant-speed engines with maximum
power less than 19 kW, and for constant speed engines with maximum power 19≤kW<37 and rated speed equal to or greater than 3,000 rpm is
covered under warranty for a period of two (2) years or 1,500 hours, whichever
occurs first. If any emission related part on your engine is defective, the part will be repaired or replaced by Kohler Co.
OWNER’S WARRANTY RESPONSIBILITIES:
As the heavy-duty off-road engine owner, you are responsible for the performance of the
required maintenance listed in your Kohler Co.
owner’s manual
. Kohler Co. recommends that you retain all receipts covering maintenance on your heavy-duty off-road engine, but Kohler Co.
cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all recommended scheduled maintenance.
As the heavy-duty off-road engine owner, you should however be aware that Kohler Co. may deny you warranty coverage if your heavy-duty off-
road engine or emission control related component has failed due to abuse, neglect, improper maintenance or unapproved modifications.
Your engine is designed to operate on commercial diesel fuel (No. 1 or No. 2 low sulfur or ultra low sulfur diesel fuel) only. Use of any other fuel
may result in your engine no longer operating in compliance with California’s emissions requirements.
You are responsible for initiating the warranty process. The Air Resources Board suggests that you present your heavy-duty off-road engine to a
Kohler Co. dealer as soon as a problem exists. The warranty repairs should be completed by the dealer as expeditiously as possible.
