Further, the Terms and Conditions herein shall only apply to Services on a product which has been sold directly by OKAI (“Product”).

Abstract of the General Terms and Conditions of Sale:

Section 8 “Seller warrants and represents that the Product is at delivery free from defects in design, materials and workmanship and conforms to any specifications provided for one (1) year. A Product is considered defective only if it is not compliant with the specifications thereof. The Warranty is limited to the repair or replacement of the Products which are determined to be defective through inspection and evaluation by the Seller or a representative designated Seller. This Warranty shall be null and void if the Product is found to have been damaged due to misuse or mishandling, or any unintended use. This Warranty shall not apply to normal tear and wear.

Shipping the Product to the Seller for return or repair and/or replacement will be the responsibility of Buyer unless otherwise agreed in writing by the parties. Shipping the Product back to Buyer after repair or replacement will be the responsibility of the Seller. Any unauthorized repair or alteration of the Product will void this Warranty in its entirety. Except as provided in this section, Seller makes no representation or warranty of any kind, express or implied, including without limitation warranties of merchantability or fitness for a particular purpose. For the avoidance of doubt, Seller is not responsible for any warranty Buyer provides to its customers which deviates from this section.”


Any customer who wishes to receive Services from OKAI shall send the After-Sales Form duly completed together with a fair description of the defect(s) to the email address: The Product should be shipped in the original packaging to the address:

Shipping the Product to OKAI for return or repair and/or replacement will be the responsibility of the customer. Shipping the Product back to Buyer after repair or replacement will be the responsibility of Seller.


The provision of Services shall not renew the original Warranty period applicable to the serviced Product. If a defect arises in a replacement part or a replacement Product during the rest of Warranty period, OKAI will, at its option, either

(a) re-perform Services on the Product, or

(b) repair or replace the replacement part or the replacement Product, using parts or Products that are new or equivalent to new in performance and reliability. If a defect arises in a replacement part or a replacement Product after the original Warranty period, Services may be provided in accordance with the provisions of Section 4 below.



If the Product is considered to be serviceable however outside the scope of Warranty, at the customer’s request and costs, OKAI may provide the customer with a quotation for its Services stating the content and the costs of Services which are needed to be carried out in order to remedy the defects in the Product.


Any expenses and risks arising from transporting the Product for maintenance, repair or overhaul by OKAI shall be borne by the customer unless otherwise agreed in writing by the parties. At the customer’s request and costs, OKAI may arrange for insurance against damage or loss of the Product in transit by reason of theft, breakage, fire and the like. During the course of Services at OKAI’s site, OKAI provides no insurance against and is not liable for, any damage or loss of the Product due to e.g. fire, water, storms, machine breakage and the like, unless such insurance is expressly requested and paid for by the customer in advance.


OKAI represents and warrants that OKAI will perform Services pursuant to the provisions of these Terms and Conditions and in a workmanlike manner. In the event that Services are, according to OKAI, defective, OKAI will, to the exclusion of any further claims of the customer, be obliged to remedy the defect. No other representations or warranties, express or implied, have been provided by OKAI.



OKAI may charge the customer an inspection and evaluation fee (including shipping costs) if,

  1. customer’s Product does not fall within Warranty as claimed;
  2. customer’s Product does not require any Services;
  3. Services cannot be performed because e.g. the serial number has been altered, defaced or removed; or
  4. iv. the Products are not serviceable due to any other reasons, e.g. the product is beyond repair.

OKAI will retain the replaced part or Product that is exchanged during Services as its property, and the replacement part/Product will become the customer’s property. If mandatory law requires OKAI to return a replaced part/Product to the customer, the customer shall pay OKAI for the retail price and the shipping costs of such replacement part/Product.


Services shall be provided at the OKAI’s premise unless otherwise agreed on. In the event that the parties agree on that Services will be provided at the customer’s site, the provisions of this sub-section

  6. If necessary, the customer shall procure internal work authorizations, ID cards and the like at his own expense; and
  1. Any and all travel costs incurred by OKAI in connection therewith shall be borne by the customer and charged by OKAI separately.

Costs and expenses incurred for any interruptions of Services or exceedance of agreed time limits for completion of Services not attributable to OKAI shall be borne by the customer.

Claims for defective Services should be made within [ten (10)] working days after the customer’s receipt of the serviced Product.

OKAI shall not be responsible for any loss, damage or distortion of data due to Services.


If and to the extent that either Party’s performance of its obligations under this Agreement is impeded or made unreasonably onerous by circumstances beyond its reasonable control that it could not reasonably have been expected to have taken into account at the time the Agreement was entered into or to have avoided or overcome the effects of, such Party shall be released from liability in damages and any other liabilities for delay in performing or failure to perform such obligations.

The limitation of liability provisions shall not apply in the event of a) intent, b) gross negligence, c) damages to life, body or health, d) fraudulent concealment of damages, or e) liability according to any applicable mandatory law. In case of slight negligence, OKAI’s liability shall be limited to the typically foreseeable damage. Any further liability shall be disclaimed.
