Warranty Policy

Limited Warranty on Purchase of New Equipment

  1. Limited Warranty. Hamilton Engine LLC, referred to herein as Hamilton Power Solutions (“HPS”), warrants to the original purchaser (“Purchaser”) of each new engines (HPS engine products), auxiliary system, generator, and other assembly built and sold by HPS (“Equipment”) that the Equipment will be free from defects in materials supplied by HPS and free from defects in workmanship performed by HPS under normal use and service for a period of 12 months or 1,000 hours from the date of shipment.

    HPS does not provide any warranty, and HPS specifically disclaims any liability, relating to defects in components or parts of the Equipment that are manufactured and/or supplied by others, including, by way of example, but not limitation, engines manufactured by Deutz, Isuzu, Hatz, and Scania. Purchaser’s warranty rights, if any, regarding such components and parts are limited to the warranty extended by such original equipment manufacturers (“OEMs”) and suppliers, if transferable, and are otherwise subject to any registration requirements. To the extent transferable, HPS hereby assigns to Purchaser such rights (if any) under such manufacturers’ and/or suppliers’ warranties.

    Subject to the foregoing limitation, HPS will repair or replace defective Equipment (or component parts of the Equipment) when such defects are due to defective materials supplied by HPS or defective workmanship performed by HPS, provided that the Equipment shall have been properly placed into service and operated in accordance with HPS’s instructions. HPS shall not be liable for breach of this limited warranty unless: (i) Purchaser provides written notice of the defective Equipment to HPS within ten (10) business days of the time when Purchaser discovers or ought to have discovered the defect, or, in the case of a latent defect, ninety (90) days from the date of shipment, along with a full description of the defect and any additional details that may be beneficial to HPS in remedying the defect; (ii) HPS is given a reasonable opportunity after receiving written notice of any breach of warranty to examine such Equipment and Purchaser (if requested to do so by HPS) returns such Equipment (or component part) to HPS’s place of business, or such other location as directed by HPS, at HPS’s cost, for the examination to take place there; and (iii) HPS reasonably verifies Purchaser’s claim that the Equipment (or component part) is defective. Purchaser shall bear all risk of further damage to the Equipment (or other component parts of the Equipment) resulting from Purchaser’s failure to notify HPS of the defect or to otherwise take reasonable measures to minimize or mitigate further damage. Transportation and labor charges covering any Equipment or part thereof returned, which proves not to be defective, shall be at Purchaser’s expense.

    HPS’s sole obligation to Purchaser is limited to the repair or replacement of any item which HPS, in its sole discretion, determines to be defective and for which HPS is otherwise responsible. The decision to repair or replace shall be at HPS’s sole option. Warranty work must be performed by HPS or an HPS-authorized repair service. Any steps taken by HPS to correct defects shall not act to extend the term of the warranty. Any parts that have been replaced shall be made available to HPS and shall be HPS’s property.

    This limited warranty does not extend or apply to any loss or damage due to misuse; accident; abuse; vandalism; normal wear and tear; negligence (other than HPS’s); unauthorized modification or alteration; use beyond rated capacity; environmental conditions, natural disasters, or other causes beyond the reasonable control of HPS; acts of God; improper or unauthorized installation, repair, handling, maintenance, adjustment, or application; damages caused by failure to follow HPS’s maintenance procedures outlined in the applicable owner’s manual; or any other cause not the fault of HPS.

This limited warranty is personal to Purchaser and may not be transferred or assigned without the prior express written consent of HPS.

HPS SHALL NOT BE SUBJECT TO ANY OTHER OBLIGATIONS OR LIABILITIES, WHETHER ARISING OUT OF BREACH OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE AND STRICT LIABILITY), OR UNDER OTHER THEORIES OF LAW OR EQUITY, WITH RESPECT TO EQUIPMENT SOLD BY HPS, OR ANY UNDERTAKINGS, ACTS OR OMISSIONS RELATING THERETO. FURTHER, IN NO EVENT WILL HPS BE LIABLE OR RESPONSIBLE FOR AND DISCLAIMS ANY AND ALL SPECIAL, INCIDENTAL, INDIRECT, CONTINGENT, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES OF ANY NATURE WHATSOEVER. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, HPS SPECIFICALLY DISCLAIMS ANY LIABILITY FOR PROPERTY DAMAGES, PENALTIES, LOST PROFITS OR REVENUE, DOWN-TIME OR LOSS OF USE, LOST GOOD WILL, COST OF CAPITAL, COST OF SUBSTITUTE GOODS OR SERVICES, OR FOR ANY OTHER TYPE OF ECONOMIC LOSS, OR FOR CLAIMS OF PURCHASER’S CUSTOMERS OR ANY THIRD PARTY FOR ANY SUCH DAMAGES, COSTS, LOSSES, OR EXPENSES. EACH PROVISION HEREOF THAT PROVIDES FOR A LIMITATION OF LIABILITY, DISCLAIMER OF WARRANTY OR CONDITION, OR EXCLUSION OF DAMAGES IS SEVERABLE AND INDEPENDENT OF ANY OTHER PROVISION AND IS TO BE ENFORCED AS SUCH.
