LIMITED WARRANTY
DAYTON FIVE-YEAR LIMITED WARRANTY. Professional-duty Electric Generators, Models covered in this manual, are warranted by Dayton Electric Mfg. Co. (Dayton) to
the original user against defects in workmanship or materials under normal use for one year after date of purchase. Any part which is determined to be defective in material
or workmanship and returned to an authorized service location, as Dayton designates, shipping costs prepaid, will be, as the exclusive remedy, repaired or replaced at
Dayton’s option. For limited warranty claim procedures, see PROMPT DISPOSITION below. This limited warranty gives purchasers specific legal rights which vary from
jurisdiction to jurisdiction.
LIMITATION OF LIABILITY. To the extent allowable under applicable law, Dayton’s liability for consequential and incidental damages is expressly disclaimed. Dayton’s liability in all
events is limited to, and shall not exceed, the purchase price paid.
WARRANTY DISCLAIMER. Dayton has made a diligent effort to provide product information and illustrate the product in this literature accurately; however, such information and
illustrations are for the sole purpose of identification, and do not express or imply a warranty that the products are MERCHANTABLE, or FIT FOR A PARTICULAR PURPOSE, or that the
products will necessarily conform to the illustrations or descriptions.
Except as provided below, no warranty or affirmation of fact, expressed or implied, other than as stated in “LIMITED WARRANTY” above is made or authorized by Dayton.
PRODUCT SUITABILITY. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products for certain purposes, which may vary from
those in neighboring areas. While Dayton attempts to assure that its products comply with such codes, it cannot guarantee compliance, and cannot be responsible for how the product is
installed or used. Before purchase and use of a product, review the product applications, and all applicable national and local codes and regulations, and be sure that the product,
installation, and use will comply with them.
Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so
the above limitation or exclusion may not apply to you; (b) also, some jurisdictions do not allow limitations on how long an implied warranty lasts, consequently the above limitation
may not apply to you; and (c) by law, during the period of this Limited Warranty, any implied warranties of implied merchantability or fitness for a particular purpose applicable to
consumer products purchased by consumers, may not be excluded or otherwise disclaimed.
PROMPT DISPOSITION. Dayton will make a good faith effort for prompt correction or other adjustment with respect to any product which proves to be defective within limited
warranty. For any product believed to be defective within limited warranty, first write or call dealer from whom product was purchased. Dealer will give additional directions. If unable to
resolve satisfactorily, write to Dayton at address below, giving dealer’s name, address, date and number of dealer’s invoice, and describing the nature of the defect. Title and risk of loss
pass to buyer on delivery to common carrier. If product was damaged in transit to you, file claim with carrier.
