All OTC products and parts, with the exceptions noted below or otherwise stated under a separate warranty, are warranted against defects in materials and workmanship for the life of the product or part. The life of the product or part is defined as that point in time when the product or part no longer functions due to normal wear.

OTC's warranty is expressly limited to the original retail purchaser of the products or parts for use in the ordinary course of the buyer's business. This warranty does not cover any product or part that has been abused, worn out, contaminated, rusted, heated, ground, or otherwise altered, damaged due to side loading, used for a purpose other than for which it was intended, or used in a manner inconsistent with any instructions regarding its use.

Chains, batteries, electric motors, knives, and cutter blades, which are sold with OTC products, are not covered by this warranty. Electric motors are separately warranted by their manufacturers under conditions stated in their warranties. Additional OTC products, including electronic products, may be covered under independent warranties.

THIS WARRANTY IS EXCLUSIVE, AND OTC MAKES NO OTHER WARRANTY OF ANY KIND WHATSOEVER, EXPRESSED OR IMPLIED, WITH RESPECT TO THE PRODUCTS MANUFACTURED AND SOLD BY IT, WHETHER AS TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR ANY OTHER MATTER. No agent, employee, or representative of OTC has any authority to bind OTC to an affirmation representation or warrant concerning OTC products or parts except as stated herein.

To qualify for warranty consideration, return the OTC product, freight prepaid, to an OTC authorized hydraulic service center. If any product or part manufactured by OTC is found to be defective by OTC, in its sole Judgment, OTC will, at its sole option, either repair or replace such defective product or part and return it via best ground transportation, freight prepaid.

THIS SHALL BE THE EXCLUSIVE REMEDY AVAILABLE FOR ANY DEFECTS IN THE PRODUCTS OR PARTS MANUFACTURED AND SOLD BY OTC, OR FOR DAMAGES RESULTING FROM ANY OTHER CAUSE WHATSOEVER, INCLUDING WITHOUT LIMITATION, OTC'S NEGLIGENCE. OTC SHALL NOT IN ANY EVENT BE LIABLE TO ANY BUYER FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY KIND, WHETHER FOR DEFECTIVE OR NON-CONFORMING GOODS, NEGLIGENCE, ON THE BASIS OF STRICT LIABILITY, OR FOR ANY OTHER REASON.

The purpose of this exclusive remedy shall be to provide the buyer with repair or replacement of products or parts manufactured or distributed by OTC found to be defective in materials or workmanship or negligently manufactured. This exclusive remedy shall not be deemed to have failed its essential purpose so long as OTC is willing and able to repair or replace said defective products or parts in the prescribed manner
