WARRANTY AND RETURNS
WARRANTY POLICY FOR LAVINA®ELITE 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.

1. GENERAL INFORMATION
This owner’s manual is intended for the operator of the Lavina®ELITE machine, the servicing technician as well as for anyone
involved with operating or servicing the machine. We recommend that you read the instructions very carefully and follow
them strictly. The manual includes information about assembling, using, handling, adjusting and maintaining your Lavina®
ELITE floor grinding and polishing machine.
1.1 MANUFACTURER
Superabrasive was founded in 1987, as a manufacturer of high quality diamond tools for the stone and concrete industry.
Today, Superabrasive is one of the world’s leading companies in the production of diamond tools and floor grinding
machinery. At Superabrasive, we strive to deliver the very best solutions to our customers, and enable them to work more
efficiently.
1.2 GENERAL DESCRIPTION
The Lavina®ELITE machine is intended for grinding, polishing and buffing concrete, marble, granite, limestone and terrazzo
surfaces with diamond tools. Additionally, the machine could be used for grinding wood floor surfaces.
The Lavina®ELITE machine is a three-disc machine, which can be used wet or dry.
For best results, use only tools manufactured or recommended by Superabrasive and its distributors.
The Lavina® ELITE machine is manufactured and fitted for the above-mentioned applications only! Every other
use may possess risks to the persons involved.
1.3 ENVIRONMENTAL CONDITIONS
The temperature range for operating the Lavina® ELITE machine outdoors is between 41°F and 86°F or 5°C and 30°C.
Never use the Lavina® ELITE machine during rain or snow when working outdoors. When working indoors, always
operate the machine in well‐ ventilated areas.
1.4 VACUUM CONNECTION
A connection for a vacuum dust extractor is located on the carriage. The Lavina® ELITE machine does not include a vacuum
dust extractor. The customer must purchase the vacuum dust extractor separately. The vacuum dust extractor must be
adapted for floor grinders and have a minimum air displacement of 310m3/h with a negative vacuum of 21 kPa.
1.5 LAVINA® 20EU MAIN COMPONENTS
The Lavina®ELITE machine is made of two main component sections:
1.5.1 Carriage which contains:
Handle - the handle on the frame is adjustable in height and allows the operator to work in a correct and safe
posture (see point 3. Handling and transportation).
LED lights - the LED lights (Fig.1.1; Fig.1.2) enables the operator to work in darker areas. Existing lighting
system does not replace adequate overhead lighting.
The control panel (fig.1.3) is positioned on top of the frame and contains buttons and switches for start/stop
the machine also for the pump, lights, RPMs control switch, hour meter unit, EMG button and the USB port
for charging your phone.
The water tank is on the opposite side of the frame, so that the weight of the water does not affect
the operation of the machine. The frame weight, on the other hand, is fully absorbed by the driving
wheels. An electric pump sprays the water through a front mist system or internal under cover.
Power box
Water pump
1.5.2 Machine head which contains:
The Electric motor - its mounted on the base plate and it is driving the three heads with a belt system.
The planetary motion - it derives from the main engine, driven by a simplex roller chain.
The self‐leveling Guard is designed to have contact with the surface. Anytime, no matter the height
of the tool used.
 “Quickchange” tool holder is designed to hold the tools with “Quickchange”connection (All of our new
tools use the “Quickchange” connection and there is no more foam holders).
