GENERAL INFORMATION
Polished concrete surfaces are getting more and more popular because the aesthetics in rooms is as
important as the solidity and stability of the construction. Generally, ‘polishing’ concrete surfaces means
making them smooth and sparkling. Polished surface requires minimum maintenance, it has good
resistance and it is absolutely ecological. Polishing machines have great power and work very fast. Thus
they polish the surface until it gains the required glitter.

Manufacturer
Superabrasive was founded more than 20 years ago, in 1986, 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. We periodically
continue to develop new technologies and ideas in an effort to manufacture the most efficient machines.
General Description
The Lavina 16
limestone and terrazzo surfaces with diamond tools.
The Lavina 16
®
machine is intended for grinding, polishing and buffing concrete, marble, granite,
®
is a three-disc machine which can be used dry as well as wet (without dust) by moving
away the upper layer of different kinds of stones and thus making them smooth and polished.
For best results, use only tools manufactured or recommended by Superabrasive and its distributors.
Additionally, the machine could be used for grinding wood floor surfaces.
WARNING! The Lavina 16
®
machine is manufactured and fitted for the above-mentioned applications
only! Every other use may possess risks to the persons involved. Do not use the Lavina 16
any other applications except for the ones specified in this manual!

Machine characteristics
The Lavina 16
water tank, the electrical box and the controls; and the main head (2)
®
is made of two main component sections: carriage (1), which includes the frame, the
, which includes the motor, the base
plate and the 3 planetary heads with the tool holders.

Main design
Figure 1
The two main component sections, the carriage and main head, are easy to disassemble, light to lift and
easy to ship.
• The handle on the frame is adjustable in height and allows the operator to work in a correct and
safe posture.
• The frame itself is functioning as an electrical box. The electrical box contains the electric
switching devices and the inverter. The main feeding cable is in the upper part of the frame , and the
motor feeding cable is plugged in the outlet located at the bottom of the frame. On the frame there are
holders for the vacuum hoses and a Y-pipe and it functions as a connection between the vacuum cleaner
and the vacuum ports going out from the main head base. (Fig. 2)
Figure 2
• The controls are positioned in front of the handle and are easy to activate form the operator in
working position (Fig.3).

• 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 frame weight, on the other hand, is totally absorbed by
the driving wheels.
• The self-leveling guard assembly is designed of a heavy material so that the guard has contact
with the ground at all times regardless of the thickness of the tools used. The guard adjusts its position
depending on the tool height used.
• The motor is mounted on the base plate and is driving the three planetary heads with a belt
system. Two of these heads have an opposite rotating direction, while the third head’s rotating direction
is responsible for rotating the whole planetary system. The three mounting plates could be floating
(flexible, and following the surface) or non-floating (rigid). Which plates are used depends on the work to
be done. A tool holder plate with a specially enclosed tool is mounted on each of the three mounting
plates.

Vibrations
The vibrations of the machine are within the limits of directive 2003/10/EC (the seventeenth individual
Directive of Article 16(1) of Directive 89/391/EC) when the Lavina 20

tools and in normal conditions.
Sonorous Emissions
The sonorous emissions are, also within the limits of directive 2003/10/EC (the seventeenth individual
Directive of Article 16(1) of Directive 89/391/EC). However, as previously stated, the operator must wear
ear protectors.
Vacuum Connection
A connection for a vacuum dust extractor is located on the carriage. The Lavina 16
®
does not include a
vacuum dust extractor. The customer must purchase the vacuum dust extractor separately. The tube of
the vacuum extractor must be Ø 50 mm and can be glided over the pipe.
The vacuum dust extractor must be adapted for floor grinders and have a minimum air displacement of
20m3/h with a negative vacuum of 21 kPa.
