LIMITED WARRANTY and LIMITATION OF LIABILITY
Allen Engineering Corporation (“Allen”) warrants its products to be free of defects in material or workmanship for the following
periods:
A. New Machines and Parts............................................................................................One Year
Warranty period begins on rst day of use by End User. This rst day of use is established by the date of a completed Allen
Warranty Card or a Bill of Sale to the End User. All warranty is based on the following limited warranty terms and conditions,
including the disclaimer of implied warranties and consequential damages.
1. Allen’s obligation and liability under this warranty is limited to repairing or replacing parts if, after Allen’s inspection, there is
determined to be a defect in material or workmanship. Allen reserves the choice to repair or replace.
2. If Allen chooses to replace the part, it will be at no cost to the customer and will be made available to the Allen Distributor,
Dealer, or Rental Center from whom the End User purchased the product.
3. Replacement or repair parts, installed in the product, are warranted only for the remainder of warranty period of the product
as though they were the original parts.
4. Allen does not warranty engines. Engine warranty claims should be made directly to an authorized factory service center
for the particular engine manufacturer.
5. Allen’s warranty does not cover the normal maintenance of products or its components (such as engine tune-ups and oil &
lter changes). The warranty also does not cover normal wear and tear items (such as belts and consumables).
6. Allen’s warranty will be void if it is determined that the defect resulted from operator abuse, failure to perform normal main-
tenance on the product, modication to product, alterations or repairs made to the product without the written approval of
Allen. Allen specically excludes from warranty any damage to any trowels resulting from an impact to the rotors.
7. Impact damage is not covered under the Allen Gear Box warranty.
8. Allen will pay shop labor on warranty items at the Allen Shop Labor Rate in existence on the date of the warranty claim.
An Allen Labor Chart will determine the time allowed to complete a repair and will govern the shop labor hours that will be
allowed.
9. Allen will pay freight on warranty replacement parts at worldwide standard ground rates. No warranty replacement parts
will be shipped air freight at the expense of Allen. Allen only pays outbound freight charges when sending warranty replace-
ment parts to the customer via ground service. Allen does not pay any inbound freight. However, if Allen determines this to be
a warranted item, only then will Allen reimburse the customer for inbound freight at standard ground rates.
10. ALLEN ENGINEERING CORPORATION’S WARRANTY POLICY WILL NOT COVER THE FOLLOWING: TAXES;
SHOP SUPPLIES; ENVIRONMENTAL SURCHARGES; AIR FREIGHT; TRAVEL TIME; LOSS OF TIME; INCONVENIENCE;
LOSS OF RENTAL REVENUE; RENTAL COSTS OF EQUIPMENT USED TO REPLACE THE PRODUCT BEING REPAIRED;
LOSS OF USE OF THE PRODUCT; COMMERCIAL LOSS; OR ANY OTHER CHARGES WHATSOEVER OR ANY LIABILI-
TIES FOR DIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGE OR DELAY.
11. ALLEN ENGINEERING CORPORATION MAKES NO OTHER WARRANTY, EXPRESSED OR IMPLIED. THIS LIMITED
WARRANTY IS IN LIEU OF THE WARRANTY OF MERCHANTABILITY AND FITNESS. THERE ARE NO OTHER
WARRANTIES THAT EXTEND BEYOND THE DESCRIPTION ON THIS DOCUMENT.
12. No Allen employee or representative is authorized to change this warranty in any way or grant any other warranty unless
such change is made in writing and signed by an ofcer of Allen Engineering Corporation.
