4.2.2 WARRANTY
The following statement is hereby provided as required by regulations of the United States Environmental
Protection Agency (EPA).
YOUR WARRANTY RIGHTS AND OBLIGATIONS
All off-road large spark-ignition (LSI) engines must be designed, built and equipped to meet the Federal EPA's
stringent anti-smog standards.
Komatsu Forklift USA, LLC ("KFI") must warrant the emission control system on your engine for the periods of time
listed below provided there has been no abuse, damage, neglect or improper maintenance of your engine.
Your emission control system may include parts such as the carburetor, regulator or fuel-injection system, ignition
system, engine computer unit (ECM), catalytic converter and air induction system.
Also included may be sensors, hoses, belts, connectors and other emission-related assemblies.
Where a warrantable condition exists, an Authorized Komatsu Forklift Dealer will repair your LSI engine at no cost
to you, including diagnosis, parts and labor.
MANUFACTURER'S WARRANTY COVERAGE
Beginning January 1, 2004 off-road large spark-ignition EPA engines are warranted for the time periods listed
below. If any emission-related part on your engine is defective, the part will be repaired or replaced by an
Authorized Komatsu Forklift Dealer.
OWNER'S WARRANTY RESPONSIBILITIES
As the off-road LSI engine owner, you are responsible for the performance of the required maintenance listed in
your Operation and Maintenance Manual.
KFI recommends that you retain receipts covering maintenance on your off-road engine, but KFI cannot deny
warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
As the off-road large spark-ignition engine owner, you should be aware, however, that KFI may deny you warranty
coverage if your off-road large spark-ignition engine, or a part thereof, has failed due to abuse, damage, neglect,
improper maintenance or unapproved modifications.
Your engine is designed to operate on gasoline and/or LPG fuel. Use of any other fuel may result in your engine no
longer operating in compliance with the Federal EPA's emissions requirements.
You are responsible for initiating the warranty process. It is suggested that you present your off-road large spark-
ignition engine to an Authorized Komatsu Forklift Dealer as soon as you become aware that a problem exists. The
warranty repairs should be completed by the dealer as expeditiously as possible.
If you have any questions regarding your warranty rights and responsibilities, you should contact the Komatsu
Forklift Product Support Dept. at (847) 437-5800.
