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.

Machine characteristics
The Lavina 25®N/25®NHV is made of two main component sections: the carriage (1), which includes the
frame, the water tank, the electrical box and the controls; and the main head (2), which includes the
motor, the base plate and the 3 planetary heads with the tool holders.
Lavina 25®N/25®NHV 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 halogen spotlight (Fig.2) attached to the frame enables the operator to work in darker
areas.
Figure 2
Existing lighting system does not replace adequate overhead lighting. To
avoid accidents use the Lavina 25®N/25®NHV only in well enlighten environments.
The frame itself is functioning as a vacuum hose and also acts as a connection between the
vacuum attachment hose and the two hoses coming out of the head base.
The controls are positioned on top of the electrical box and are easy to activate form the
operators working position.

Superabrasive Owner’s Manual – Lavina25®N/25®NHV 1/2012

Figure 3
The electrical box contains the electric switching devices and the inverter. The motor feeding
cable and the main feeding cable are plugged in the socket located on the bottom of the box.
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 skirt is designed of a heavy material so that the skirt has contact with the
ground at all times regardless of the thickness of the tools used. The skirt 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. The Lavina 25®N/25®NHV machine is a planetary movement machine. The planetary motion
derives from the friction between the tools and the floor, which is allowing the tools to spin in either
clockwise or counterclockwise direction. The design ensures that the tools will not force themselves
against the resistance of the floor surface. Instead, the machine will alternate directions to accommodate
to a “high spot” or a “low spot” imperfections in the floor without causing damage to the floor or the
machine.

Starting the Machine
First, follow the directions in chapter Safety Devices and Safety Instructions.
Next, pull the emergency stop o ensure that the machine is in working condition.
Check the potentiometer and ensure that it is set at an approximate working speed.
If working wet, add water to the floor surface to prevent the tools from scratching the floor.
If working dry, omit this step, and instead, switch on the vacuum unit. Finally, hold the machine firmly and push
the start button.
Operating the Machine
Guide the machine in straight lines across the floor, and with each new line overlap a little bit of the previously
completed surface. Work at a constant speed allowing the tools time to work at a speed appropriate for the
tools’ grit size. Never stop the Lavina 25®N/25®NHV machine in one spot while the tools are still working
because they will leave marks on the floor surface. When working wet, open the water tank periodically to
release water onto the floor surface. When working dry, check the floor surface periodically to ensure that dust
is not accumulating on the surface. Also, clean the vacuum if necessary.
Stopping the Machine
Stopping the machine must be done in a fluid movement. Do not stop the machine before arresting the motor
with the Emergency Switch button.
Remember not to hold the machine in one spot before turning off the motor as the tools could damage the
surface.
TOOLS AND ACCESSORIES
Weights
Superabrasive offers additional weights for
increasing the productivity of the machine (Fig.12).
Each additional weight weighs about 29 kg.
The number of weights you choose to use will vary
from none to two. Each individual application, type
and condition of surface, power capacity of the
outlet, etc. will determine the number of weights you
can use without tripping a breaker. The first weight
stacks onto three nylon posts around the outer
bowl. The second weight stacks onto the first.
The additional weights depend on the tools, it is not
always possible to add weights. Some tools work
too aggressively and the machine can stop.
The weight can be ordered with No A08.00.00.00
