Graco Standard Warranty

Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing its name to be free from defects in 

material and workmanship on the date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty 

published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by 

Graco to be 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 general wear and tear, or 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 of Graco equipment with 

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 claimed defect. 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 include the costs of parts, labor, and transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED 

TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE

Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy 

(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or 

consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

GRACO MAKES NO WARRANTY, AND DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A

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

warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or 

the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the
