WARRANTY AND RETURNS



WARRANTY POLICY FOR LAVINA® X 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 200 operating hours. 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® X MACHINES

The Lavina® X 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.

6. POPULAR TOOLS



RECOMMENDEDTOOLS



QuickChange System and Tooling feature extremely fast and convenient tool changes,

and a long tool

life, providing for great longterm cost savings. The QuickChange pads

are produced in four different

bonds for super hard, hard, medium and soft concrete, in a

variety of grit sizes. They are offered with

1 or 2 buttons or rectangular segments, which allows you to customize the aggressiveness of

the cut.



Calibra grinding discs: our popular ceramic bond discs are designed for the removal of difficult

scratches

and they save you valuable time by eliminating the need for multiple passes with metal

tools. They can be

used wet or dry, and are best for hard concrete applications.

They are 3-inch, with included Velcro back attachment.







NATO® polishing discs feature a special resin formula designed for both wet and dry applications and a

unique design with

wide channels allowing for work on a cleaner surface and ensuring a quality polish. Available

in 3 and 4 in sizes. They are with

included Velcro attachment.







VHARR® Premium Polishing Pads are designed for mechanically polishing and restoring concrete; also

ideal for terrazzo and

hard stone floors. VHARR® pads are offered in a wide variety of diameters and grit

sizes to accommodate many applications.

Dry use is strongly recommended.





Shine Pro® are high quality diamondimpregnated pads for floor maintenance. Available in a variety of sizes, and

are great for

daily use. When used wet, they require only water (no wax or chemicals needed) and are a very

environmentally friendly solution

for maintaining floors.
