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

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.
