Graco Standard Warranty

Graco warrants all equipment manufactured by Graco 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.  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 accor-
dance 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 sub-
stitution 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 particular purpose in connection
with accessories, equipment, materials or components sold but not manufactured by Graco.  These items sold, but not manufactured
by Graco (such as electric motors, switches, hose, etc.), are subject to 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 negligence of Graco, or otherwise.
