The Graco Warranty and Disclaimers

WARRANTY
Graco warrants all equipment manufactured by it and bearing its name to be free from defects in material and
workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use.  As
purchaser’s sole remedy for breach of this warranty, Graco will, for a period of twelve months or two thousand
hours of operation from time of sale, repair or replace any part of the equipment proven defective.  This warranty
applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.

This warranty does not cover, and Graco shall not be liable for, any malfunction, damage or wear caused by faulty
installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident,
tampering, or substitution of non-Graco component parts.  Nor shall Graco be liable for malfunction, damage or
wear caused by the incompatibility with Graco equipment of structures, accessories, equipment or materials not
supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures,
accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized
Graco distributor for verification of the claim.  If the claimed defect is verified, Graco will repair or replace free of
charge any defective parts.  The equipment will be returned to the original purchaser transportation prepaid.  If
inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a
reasonable charge, which charges may includes the costs of parts, labor and transportation.

DISCLAIMERS AND LIMITATIONS
The terms of this warranty constitute purchaser’s sole and exclusive remedy and are in lieu of any other warranties
(express or implied), including warranty of merchantability or warranty of fitness for a particular purpose,
and of any non-contractual liabilities, including production liabilities, based on negligence or strict liability.  Every
form of liability for direct, special or consequential damages or loss is expressly excluded and denied.  In no case
shall Graco’s  liability exceed the amount of the purchase price.  Any action for breach of warranty must be brought
within two (2) years of the date of sale.

EQUIPMENT NOT COVERED BY GRACO WARRANTY
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular
purpose
, with respect to accessories, equipment, materials, or components sold but not manufactured by Graco.

warranty, if any, of their manufacturer.  Graco will provide purchaser with reasonable assistance in making any
claim for breach of these warranties.
