Warranty and Terms

Danaher Precision Systems (DPS) warrants to original equipment manu-
facturers, distributors and industrial and commercial users of its prod-
ucts that each new product manufactured or supplied by DPS shall be
free from defects in materials and workmanship. DPS’s sole obligation
under this warranty is limited to furnishing without additional charge a
replacement for, or at its option, repairing or issuing credit for any prod-
uct which shall within one year from the date of sale by DPS be returned
freight prepaid to the plant designated by DPS and which upon inspec-
tion is determined by DPS to be defective in materials or workmanship.
Complete information as to operating conditions must accompany any
product returned for inspection. The provisions of this warranty shall not
apply to any DPS product which has been subjected to misuse, improper
operating conditions or which has been repaired or altered. Seller
makes no warranty that its products are fit for the use or purpose to
which they may be put by the buyer, whether or not such use or purpose
has been disclosed to seller in specifications or drawings previously or
subsequently provided seller, and whether or not seller’s products are
specifically designed and/or manufactured for this purpose. THIS WAR-
RANTY IS IN LIEU OF ALL  OTHER WARRANTIES, EXPRESSED OR
IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILI-
TY OR FITNESS FOR  A PARTICULAR PURPOSE. DPS’s sole liability on
any such claim of any kind, whether in contract, tort or otherwise, for
any loss or damage arising out of, connected with, or resulting from the
manufacture, sale, delivery or use of the products sold thereunder shall
in no case exceed the cost of replacement or repair as provided herein.
IN NO EVENT SHALL DPS BE LIABLE FOR ANY SPECIAL, INCIDENTAL

OR CONSEQUENTIAL DAMAGES. There are no other warranties,
expressed or implied, made by DPS except the warranty against defects
in materials and workmanship set forth above and neither assumes nor
authorizes any other person or firm to assume for it any other obligations
or liability in connection with its products.

Custom design work performed by DPS will be subject to engineering
charges. Payments are due upon acceptance of the custom design
work. DPS will retain all copyright and other proprietary rights to the
product and any additional custom work. The Purchaser shall respect
the proprietary rights of DPS and shall take measures to prevent unau-
thorized disclosure of information relating to the product and any addi-
tional custom design work. DPS shall retain all proprietary rights and
shall have the right and authority to use, sell, market, research, and uti-
lize for any other purpose at it sole discretion said product and custom
design work without notification or any liability whatsoever, including
but not limited to monetary remuneration, to the Purchaser.

Prices in this quotation do not include any taxes or charges of any
nature imposed by any governmental authority which shall become
payable by reason of sale, purchase, delivery, storage, processing, use,
consumption, or shipment of equipment hereunder. All such taxes or
charges shall be the obligation of the buyer and may be either billed to
the buyer separately, or added to the price of the equipment shipped.

Field Service

Policy

Unless express shipping instructions are furnished by buyer, seller will
use its discretion. All shipments are F.O.B. seller’s plant. Upon delivery to

a common carrier, title and all risk of loss or damage in transit shall pass
to buyer.

If the system or unit cannot be made functional by no-charge tele-
phone assistance or purchased replacement parts, and cannot be
returned to the DPS factory for repair, then the following field service
policy will apply: DPS will provide an on-site field service representa-
tive in a reasonable amount of time, provided that the customer issues
a bonafide purchase order to DPS covering all transportation and sub-

sistence costs and the prevailing cost per hour (eight hour minimum)
including travel time necessary to complete the repair, regardless of
warranty determination. If the DPS field service representative deter-
mines during his on-site repair that the system or unit’s problem is not
warranty-related, then the prevailing service charge per hour (eight-
hour minimum) shall be assessed against the issued purchase order.

Order

Cancellation Policy

Blanket Order

Policy

Any order placed with DPS that has more than one delivery date for
the same line item shall be termed a Blanket Order, and is is subject
to the following conditions:
• Specific ship dates must be given for the entire quantity of each

item when an order is placed. DPS must receive written confirma-
tion of a purchase order verifying these dates.

• The entire quantity of each item on an order must be shipped within

12 months of receipt of order.

• DPS reserves the right to refuse any rescheduling of delivery dates. 
• Quantity increases to items on existing orders may not be subject to

the same quantity discount as given on the original order.

Prices and specifications are subject to change without notice.

Claims for incorrect or defective materials must be received in writing
within thirty (30) days from delivery at buyer’s place of business. No
units or systems may be returned, in or out of warranty, without first
issuing a purchase order and obtaining a return authorization number
from the seller, and no  claim will be allowed nor credit given for units
or systems returned without such approval. Buyer will not be allowed
to debit accounts. All credits must be issued by seller. Units which
have been exposed to hazardous or toxic materials must be decontam-
inated at the expense of the Purchaser before being returned.
Equipment that has not been decontaminated and certified will not be
accepted for repair. After approval from DPS, the defective unit or

system is to be returned to the factory with a written statement of 

the problem and transportation prepaid. (No C.O.D. or collect freight
shipments will be accepted). After DPS’s in-plant examination, 
warranty or out-of-warranty status will be determined. If upon exami-
nation of such unit or system, warranted defects exist, then the unit 
or system will be repaired at no charge and shipped prepaid back to
the buyer, via common carrier. If an out-of-warranty situation exists,
the buyer shall be notified of the repair cost immediately. At such time,
the buyer must issue a purchase order to cover the cost of the repair
or authorize the unit or system to be shipped back as is, at the buyer’s
cost. Warranty work will be suspended when owner/user is in default
of financial obligation to seller.

Cancellation of orders consisting of standard products, for any reason, is
subject to a minimum fifteen (15) percent cancellation charge. All stan-

dard, non-standard products, custom products, or systems are subject to
a cancellation charge to be determined by DPS.
