WARRANTY AND RETURNS
WARRANTY POLICY FOR LAVINA®ЕMACHINES
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 48 contiguous
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.

In no case, a machine is to be returned to Superabrasive Inc. for credit or repair without prior authorization.

1. GENERAL INFORMATION
This owner’s manual is intended for the operator of the Lavina®32RE/32REHV machine, the servicing technician, and
anyone else 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®32RE/32REHV floor grinding and polishing machine.
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.
GENERAL DESCRIPTION
The Lavina®32RE/32REHV machine is intended for grinding, polishing and buffing concrete, marble, granite, limestone
and terrazzo surfaces with diamond tools.
The Lavina®32RE/32REHV 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.
WARNING!
The Lavina®32RE/32REHV machine is manufactured and fitted for the above-
mentioned applications only! Every other use may possess risks to the persons
involved.
MACHINE CHARACTERISTICS
The Lavina®32RE/32REHV is made of two main component sections:
LAVINA®32RE/32REHV MAIN DESIGN
The two main component sections are the carriage and main head.
The handle on the frame is adjustable in height and
enables the operator to work in a correct and safe
posture.
The controls are positioned on top of the handle
(fig.1.1)
Two LED lights (Fig.1.2) enable the operator to work in
darker areas. The lamps are with magnet holder can be
adjusted in different positions.
.A LED light (Fig.1.3) lights the grinded floor behind
the machine. The lamp holder can be adjusted to
different positions.
Lighting system does not replace adequate overhead lighting.
The electrical box contains the electric switches and inverters. The motor feeding cable is plugged in the socket
located on the bottom of the box.
The main feeding cable is connected with a plug and socket on the side of the box
(fig.1.4).
The water tank is on the opposite side of the frame, so that the weight of the water has
no influence on the operation of the machine. The water from the tank is supplied by a
pump. The frame weight, on the other hand, is fully absorbed by the driving wheels.
The motor is mounted on the base plate and drives the three grinding heads with a belt
system.
The planetary head is driven by a duplex roller chain.
ENVIRONMENTAL CONDITIONS
The temperature range for operating the Lavina®32RE/32REHV outdoors is between 41°F and 86°F or 5°C and 30°C.
Never use the Lavina®32RE/32REHV during rain or snow when working outdoors. When working indoors, always
operate the machine in well-ventilated areas.
