PW 400 / PW 500 Limited Warranty

Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a
Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed
by the Distributor/OEM and accepted by RLWS. All systems and components are warranted against defects
in materials and workmanship for one (1) year.

RLWS warrants that the equipment sold hereunder will conform to the current written specifications autho-
rized by RLWS. RLWS warrants the equipment against faulty workmanship and defective materials. If any
equipment fails to conform to these warranties, RLWS will, at its option, repair or replace such goods re-
turned within the warranty period subject to the following conditions:

Upon discovery by Buyer of such non-conformity, RLWS will be given prompt written notice with a
detailed explanation of the alleged deficiencies.

Individual electronic components returned to RLWS for warranty purposes must be packaged to prevent
electrostatic discharge (ESD) damage in shipment. Packaging requirements are listed in a publication,
“Protecting Your Components From Static Damage in Shipment,” available from RLWS Equipment
Return Department.

Examination of such equipment by RLWS confirms that the non-conformity actually exists, and was not
caused by accident, misuse, neglect, alteration, improper installation, improper repair or improper testing;
RLWS shall be the sole judge of all alleged non-conformities.

Such equipment has not been modified, altered, or changed by any person other than RLWS or its duly
authorized repair agents.

RLWS will have a reasonable time to repair or replace the defective equipment. Buyer is responsible for
shipping charges both ways.

In no event will RLWS be responsible for travel time or on-location repairs, including assembly or
disassembly of equipment, nor will RLWS be liable for the cost of any repairs made by others.

THESE WARRANTIES EXCLUDE ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE. NEITHER RLWS NOR DISTRIBUTOR WILL, IN ANY EVENT,
BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES.

RLWS AND BUYER AGREE THAT RLWS’S SOLE AND EXCLUSIVE LIABILITY HEREUNDER
IS LIMITED TO REPAIR OR REPLACEMENT OF SUCH GOODS. IN ACCEPTING THIS WAR-
RANTY, THE BUYER WAIVES ANY AND ALL OTHER CLAIMS TO WARRANTY.

SHOULD THE SELLER BE OTHER THAN RLWS, THE BUYER AGREES TO LOOK ONLY TO
THE SELLER FOR WARRANTY CLAIMS.

No terms, conditions, understanding, or agreements purporting to modify the terms of this warranty shall have any legal effect unless
made in writing and signed by a corporate officer of RLWS and the Buyer.
