1. GENERAL INFORMATION Lavina 16-X-E 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 16-X-E floor grinding and polishing machine.

MANUFACTURER

Superabrasive was founded in 1987, as a manufacturer of high quality diamond tools for the stone and concrete

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 16-X-E 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 16-X-E is a three-disc machine, which can be used for wet and dry applications.

For best results, use only tools manufactured or recommended by Superabrasive and its distributors.

The Lavina 16-X-E 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 16-X-E is made of two main component sections:

LAVINA 16-X-E MAIN DESIGN

The two main component sections are the carriage (1) and main head (2).

The handle on the frame is adjustable in height and allows the operator to work in a

correct and safe posture.

The controls are positioned on top of the frame (fig.1.2)

The electrical box (fig.1.1) contains the electric

switches 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 fully absorbed by the driving wheels.

The motor is mounted on the base plate and drives the three heads with a belt

system. The planetary head is driven by a second flat belt.

ENVIRONMENTAL CONDITIONS

The temperature range for operating the 16-X-E

Never use the Lavina 16-X-E during rain or snow when working outdoors. When working indoors, always operate

the machine in well-ventilated areas.

ELECTRICAL CONNECTION

The voltage (Volt) and power (Ampere) are displayed on a label on the electrical control box to avoid any incorrect

connection. Refer to these before connecting the power. To avoid electrical shocks, make sure the ground power

supply is functioning properly.

VACUUM CONNECTION

A connection for a vacuum dust extractor is located on the carriage. The Lavina 16-X-E does not include a vacuum

dust extractor. The customer must purchase the vacuum dust extractor separately. The hose of the vacuum

40 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 320m3/h with a negative vacuum of 21 kPa.

3. HANDLING AND TRANSPORTATION

PREPARING THE MACHINE FOR TRANSPORTATION

Unplug the motor cable plug from the control box and disconnect the water hose from the main head by

pulling it out (Fig. 3.1). Wind the electrical cable on the carriage (Fig. 3.2). Pull out the vacuum hoses (Fig.

3.3).

Release the pin sets (Fig. 3.4) attaching the head to the carriage and dismount the head from the carriage

(Fig. 3.5).

The head of the -X-E has one bar and a support used as handles intended for easy moving and

transportation.

The Lavina 16-X-E is engineered with easy transportation in mind. The ability to dismantle the machine in

two parts allows for convenient transportation and storage (Fig.3.4).

The Handle on the frame is adjustable in height and allows the operator to work in a correct and safe posture.

To adjust, simply pull the locking pin (fig.3.6) and move the frame. A loaded spring will return the pin

and lock the handle in any of several positions (fig.3.7). Choose the vertical position to easily move the

machine.

STORAGE

Always store and transport the -X-E in a dry place. Never transport the -X-E

unprotected; it may be damaged if transported unprotected during rain or snow.

4. OPERATION

PRELIMINARY CONTROLS

Inspect the working area as explained in the safety instructions. For wet use, fill in the water tank when the

electrical cable is disconnected. Connect the vacuum extractor and ensure that the vacuum hose is clear and

it will follow the machine easily. Plug in the machine and also make sure that the power cord is free to follow

the working direction of the Lavina 16-X-E.

ADJUSTING AND MOUNTING TOOLS

Mount the tools only after ensuring that there is enough diamond bond material left. Be sure that the plates

are always clean before mounting (Fig.4.1).

WARNING: Always secure (Fig.4.2), lock with the tool holder

key (Fig.4.3). Diamond tools with Velcro are attached on three 7-inch foam plates. The foam plates are

mounted on the key lock (butterfly). Always use the tool holder key (Fig.4.4).

THE CONTROL PANEL

1. Emergency button used to stop the motor in case

of emergency or disconnect fully from power

2. Inverter alarm led lights up if inverter is in alarm

mode (see Alarm)

3. Power loss led Lights on loss of power

connection (see Power loss)

4. ON/ OFF LED starts/stops the motor, lights

green when the power is on

5. Forward/Reverse switch choose forward for clockwise

rotation of the grinding plates or reverse for counter-

clockwise rotation of the grinding plates

6. Potentiometer controls the speed of the

grinding plates on a range of 300-1100 rpm

Figure 4.3 Figure 4.4

Figure 4.1 Figure 4.2

Figure 4.5

Superabrasive Original Language LAVINA 16-X-E 2/2017

STARTING THE MACHINE

Connect the machine to the power supply. Be sure the supply voltage corresponds to the voltage written on

the plate of the machine. The ON/OFF switch will light green. Turn the switch to ON. The switch button

Forward/Reverse Switch will light to indicate that it is ready, and the machine can be worked.

The Forward/Reverse Switch controls the direction of the tools. The switch should be set to forward, such that

the motor turns in counterclockwise direction (there is a symbol showing it on the motor cover).

OPERATING THE MACHINE

Guide the machine in straight lines across the floor, slightly overlapping the previously completed surface with

each new line. Work at a constant speed, allowing the tools time to work at a speed appropriate for their grit

size. Avoid vibrations. Do not stop the machine while tools are still running as they will mark the surface of the

floor. When working wet, periodically open the water tank to release water to the working surface. When

working dry, check the floor surface periodically for dust accumulation. Check regularly to see if your vacuum

works properly.

STOPPING THE MACHINE

The stopping of the machine must be done gradually until the motor stops. Do not stop moving the machine

before the motor comes to rest, as the tools could damage the surface.

To stop the machine:

1. Move the Forward/Reverse Switch to STOP

2. Turn the On/Off Switch to OFF

3. Press the Emergency Stop to dsconnect the power.

ALARM

The Alarm led (2) will light if the inverter is in alarm mode. The most common failure is motor overload. To

reset the alarm mode, disconnect the machine from the power supply.

POWER LOSS LED

When the machine stops working and the power loss led (3) flashes means that the power connection is

disconnected.
