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 veri• cation of 
the claimed defect. If the claimed defect is veri• ed, 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

(including, but not limited to, incidental or consequential damages for lost pro• ts, 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.
