AMITY TECHNOLOGY, LLC LIMITED WARRANTY FOR NEW PRODUCTS
1. General Provisions. This Warranty shall apply to the original purchaser of (1) any new and unused
machine manufactured by Amity Technology, LLC (“Amity”), and (2) any new and unused part which
is manufactured by Amity for use in an Amity machine, jointly referred to as “Products,” whether
such Product is purchased through a dealer or directly from Amity. Under this Warranty, Amity will
repair or replace, as it chooses in its sole discretion, any covered Product, or any component thereof,
which Amity determines to be defective. This Warranty shall be in effect for a period of twelve (12)
months (“the Warranty Period”), beginning on the date of delivery of the covered machine or part by
the dealer or Amity to the purchaser (“the Warranty Start Date”). The purchaser must pay the cost of
transportation of a Product to be repaired or replaced to and from an authorized Amity dealer. This
Warranty may not be transferred from the original purchaser of a Product to any other person. This
Warranty does not give a purchaser the right to any relief other than repair or replacement of the
Product, and it specifically does not allow for consequential or incidental damages, exemplary or
punitive damages, or costs and fees.
2. Scope and Limitations of Warranty. With respect to machines, this Warranty is void if any part not
supplied by Amity is used in assembly or repair of the machine, or if the machine has been altered,
abused or neglected, as determined by Amity. With respect to parts, this Warranty is void if the part
is used in any manner other than that for which it is intended. This Warranty does not extend in any
way to tires and any other component of a Product warranted by another manufacturer, a copy of
which warranty is provided herewith (“Third-Party Warranties”). In the event Amity determines that
a Product is not defective, or that any other provision of this Paragraph 2 operates to limit the
Warranty, this Warranty shall not apply and the purchaser shall be responsible for transporting the
Product from the authorized Amity dealer’s location within 10 days of notice by Amity.
3. Procedures for Obtaining Service. To secure Warranty service, a purchaser must (1) report the
defect to an authorized dealer and request repair within 45 days of the failure and within the
Warranty Period; (2) present evidence that this Warranty applies to the Product; (3) present
evidence of the Warranty Start Date; and (4) bring the Product to an authorized Amity dealer within
a reasonable period of time after reporting the defect.
4. LIMITION OF IMPLIED WARRANTIES AND OTHER REMEDIES. To the extent allowed by law, neither
Amity, its dealers, nor any company affiliated with Amity makes any warranties, representations, or
promises as to the quality, performance, or freedom from defect of any Product covered by this
Warranty.
AMITY HEREBY WAIVES, TO THE EXTENT APPLICABLE, ANY AND ALL IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. A
PURCHASER’S ONLY REMEDIES IN CONNECTION WITH THIS WARRANTY ARE THOSE SET
FORTH ON THIS PAGE. IN NO EVENT WILL AMITY, ITS DEALERS, OR ANY COMPANY
AFFILIATED WITH AMITY BE LIABLE FOR INCIDENTIAL, CONSEQUENTIAL OR PUNITIVE
DAMAGES.
Some states do not allow waivers of certain warranties, so the above waivers may not apply to you.
You may also have other rights which vary from state to state.
5. No Dealer Warranty. This is the exclusive warranty applicable to Amity Products. No dealer has any
authority to make any other warranty, modify, limit, or expand the terms of this Warranty in any
fashion, or make any representation or promise on behalf of Amity.

v
6. Dispute Resolution. Any controversy or claim arising out of or relating to this Warranty must be
settled by arbitration in Fargo, North Dakota, at a time and location designated by the arbitrator, but
not exceeding 30 days after a demand for arbitration has been made, and may be conducted by
electronic, video, or other technical means. Arbitration will be conducted by the American
Arbitration Association in accordance with its Rules of Commercial Arbitration, and judgment upon
the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. The
arbitrator will have the authority to order Amity to undertake a repair or replace any Product, at its
election, if the arbitrator finds that this Warranty requires Amity to do so. The arbitrator will not
have the authority to impose any other remedy against Amity, including without limitation
consequential or incidental damages, exemplary or punitive damages, or costs and fees.


2.9SafetyDecals

Thetypesofdecalsontheequipmentareshownintheillustrationbelow.Propersafetyrequiresthat


CAUTION:Toavoidinjuryfromescapingfluidunderpressure,
relievethepressureinthesystembeforedisconnectingor
connectinghydraulicorotherlines.Tightenallconnectionsbefore
applyingpressure.

1. Reversethetractorinlinewiththehitchstopping1foot
