WARRANTY AND RETURNS
WARRANTY POLICY FOR LAVINA® S MACHINES
A warranty card must be submitted to Superabrasive within 30 days of purchase in order for the foregoing warranty to
apply.
You can either mail a hard copy of the warranty card or submit it electronically - see page 2.
Superabrasive warrants, from the time of delivery and receipt by the original customer, new and unused products
sold by
Superabrasive or Superabrasive-appointed distributors or dealers. Goods shall be free from defects in
materials and
workmanship. Superabrasive or a Superabrasive-appointed repair facility shall either replace or
repair any defects in the
Goods resulting from faulty design, materials, or workmanship. Products repaired or
replaced during the warranty period
shall be covered by the foregoing warranty for the remainder of the original
warranty period, or ninety (90) days from date
of the repair or shipment of the replacement, whichever is longer.
Spare parts for repair will be either new or equivalent to
new.
Warranty period shall be 2 years from the time of delivery and receipt by the original customer, or 600 operating
hours on
the machine - whichever occurs first. Superabrasive will cover the shipping charges for the transportation
of the machine to
Superabrasive (or an approved repair facility) and back to the customer (within the contiguous 48
United States) in the event
that the damage occurs and is reported within the first 90 days or 200 operating hours -
whichever occurs first. Shipping
charges, if covered by Superabrasive, must be agreed upon in advance and
approved by Superabrasive. Thereafter, the
customer will have to cover the shipping charges to Superabrasive and
back. Superabrasive will not warranty Goods after a
period of 2 years from the time of delivery and receipt by the
original customer, or 600 operating hours on the machine -
whichever occurs first.
Superabrasive shall not be liable for any defects that are caused by circumstances that occur after the Goods
have been
delivered and whilst the Goods are in the possession of the purchaser. Furthermore, the warranty
does not include normal
wear and tear or deterioration. Wear parts are not warranted. Superabrasive is not liable
for defects arising out of use of
non-OEM parts.
The Warranty is void if the purchaser has not followed the maintenance plan stipulated by the machine’s manual
and
warranty card. The warranty is void if the purchaser repairs said Goods himself, or if repairs are conducted by a
repair facility
that is not approved by Superabrasive. Superabrasive’s liability does not cover defects which are
caused by faulty
maintenance, incorrect operation, faulty repair by the purchaser, or by alterations conducted
without Superabrasive’s prior
written consent. The same applies to any alterations of the Goods or services
performed by another party other than
Superabrasive, a Superabrasive-appointed distributor, or a Superabrasive-
approved repair facility. The warranty is not
applicable on a defect that arises due to tools or parts that are not
original to Superabrasive. Replaced defective parts shall
be placed at Superabrasive’s disposal and shall become
property of Superabrasive. If such defective parts are replaced
within the warranty period, the shipping charges will be covered by Superabrasive. In warranty complaint cases,
when no
defects are found for which Superabrasive is liable, Superabrasive shall be entitled to compensation for
the labor, material
cost, and shipping charges, incurred by Superabrasive as as a result of the complaint.
The warranty herein is non-transferable, and only applies to the original owner or purchaser of the machine.
RETURN POLICY FOR LAVINA® S MACHINES
The Lavina® S machines may be returned, subject to the following terms:
In no case, a machine is to be returned to Superabrasive Inc. for credit or repair without prior authorization.
Please contact
Superabrasive Inc. or your local distributor for an authorization and issuance of a return
authorization number. This number
along with the serial number of the machine must be included on all packages
and correspondence. Machines returned
without prior authorization will remain property of the sender and
Superabrasive Inc. will not be responsible for them. No
machines will be credited after 90 days from the date of
invoice.
All returns must be shipped freight prepaid. Returned machines may be exchanged for other equipment or parts of
equal
dollar value. If machines are not exchanged, they are subject to a fifteen percent (15%) restocking fee.
