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.
