1. GENERAL INFORMATION
This owner’s manual is intended for the operation of the Lavina® 32R-S/32R-S-HV 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® 32R-S/32R-S-HV 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® 32R-S/32R-S-HV machine is intended for grinding, polishing and buffing concrete, marble, granite,
limestone and terrazzo surfaces with diamond tools.
The Lavina® 32R-S/32R-S-HV is a six-disc machine with remote control, and can be used dry as well as
wet. For best results, use only tools manufactured or recommended by Superabrasive and its distributors.
WARNING!
The Lavina® 32R-S/32R-S-HV 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®32R-S/32R-S-HV is made of two main component
sections:
LAVINA®32R-S/32R-S-HV MAIN DESIGN
The two main component sections, are the carriage and the main
head.
The wheels of the carriage are driven by two gear boxes that
allow the operator to work with the machine from a distance. The
handle on the frame is adjustable in height and enables the
operator to work in a correct and safe posture/position.
Two halogen spotlights (Fig.1.2) enable the operator to work in darker areas. The lamp holder can be adjusted in
different positions.
The machine’s existing lighting system does not replace the need for
adequate overhead lighting.
A frame (U-joint technology) on top of the motor base is providing the main head a
possible to move to all sides and it gives more grinding capacity.
Remote Control Unit (fig.1.3)
The electrical box (fig.1.4) contains the electric switching
devices and inverters. The motor feeding cable is
plugged into 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. The
battery is situated under the electrical box and allows the machine to move without being
connected to a current supply.
Figure 1.3
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 water tank is supplied by a pump. The
frame weight, on the other hand, is fully absorbed by the driving wheels. The working
part of the motor is mounted on the base plate and drives the six grinding heads with a
two-belt system. The planetary head is driven by a third flat belt. The machine has a third wheel (option) which ensures
easier movement (Fig.1.4).
ENVIRONMENTAL CONDITIONS
The temperature range for operating the Lavina® 32R-S/32R-S-HV outdoors is between 41°F and 86°F or 5°C and
30°C. Never use the Lavina® 32R-S/32R-S-HV during rain or snow when working outdoors. When working indoors, always

shaft by unscrewing the bolt (Fig.3.26-1) by 3 revs. This way, releases the saw-edged bush, which transmits the
movement between the shaft and the wheel. To unscrew the bolt you need a wrench 19mm (3/4 in) (Fig.3.27). When
turning on/off the connector of the wheel it is good to lift the carriage so the wheel does not touch the floor and has
free rotation (Fig.3.28).
STORAGE
Always store and transport the Lavina® 32R-S/32R-S-HV in a dry place. Never transport the Lavina® 32R-S/32R-S-HV
unprotected; it may be damaged if transported unprotected during rain or snow.
When storing the machine, the temperature may fall down to or to less than 32F (or 0o c) you
should empty the water from the system using following steps:
- Pull out the hose of the tank (Fig.3.29)
- Using compressed air blow out the water from the system for the two positions of the turn-cock (Fig. 3.30, Fig.3.31).

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 make sure that the power cord is free to follow the working direction of the
Lavina® 32R-S/32R-S-HV.
CONTROL OF THE WATERFLOW
The operator can choose the water sprays with
valve (Fig.4.2 1)in the front (fig.4.1) when the
level of the tap is in the vertical position , when
the level is in the horizontal position water will
spray under cover of the machine.
The valve (Fig. 4.2 2) is controlling the flow of
an external water supply. A ¾” water tube can be
attached to the quick connection (Fig. 4.2 3).
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. WARNING: Always secure
the “QuickChange” pads with the security plate (Fig.4.3),
lock with the tool holder key (Fig.5.3). Diamond tools with
Velcro are attached on six 9in foam pads (Fig.4.4). The
foam plates are mounted on the key lock (butterfly).
Always use the tool holder key (Fig.5.3).
FRAME BLOCKING (U-JOINT]
The frame holds the working head and the trolley together
(U-Joint), which allows rotation of the two perpendicular
axes to better follow the profile of the floor.
The movement around one of axis can be blocked with
two screws to the plank, mounted on the front of the frame
(Fig.4.6). Unscrew the bolts and turn the plank so it fixes
the frame to the carrier with its tooth and then tighten the
bolts (Fig.4.6). Thus the lateral movement of the machine
is blocked.
CONTROL PANEL
The Control
Panel can
work connected
to the machine or
as a remote
control device.
When it is
connected to the
machine it has to
be supported by
the handle bar,
with the
transmitter panel located below. Unscrew the protective cover of the panel (Fig.4.8), and then unscrew the nut of the plug
(connecting the cable to the transmitter) and connect the plug to the panel (fig 4.10.). Put the protective cover back on
the transmitter (fig 4.11). When the panel is working as a remote control device the cable should be connected to the
transmitter.

In “LINE” position, the machine takes power from the electric
network and charges the battery. In this position the machine should
stay after stopping and switch-off. In case the battery is not fully
charged (after transporting it on self move) leave the machine connected
to the power supply in order to charge the battery.
The time to move the machine without re-charging the battery is 30 minutes.
STARTING THE MACHINE
Strictly follow the instructions in chapter "SAFETY INSTRUCTOINS".
NEVER WORK WITH THE MACHINE WITHOUT HAVING VISUAL CONTACT WITH IT.
ATTENTION: Never run the machine when you are situated between the handles of the
wheel. First turn the handles as shown on Fig.4.14.
If working wet, pour water on the floor. If working on dry surface, skip that step and
connect and switch on the vacuum cleaner. Connect the machine to the electric network
and the light "POWER" will light and put the “BATTERY-LINE” switch (Fig.4.13-3 ) in
position "LINE" . Then check the "emergency stop buttons"(Fig.4.12-2 and Fig.4.13-1)
in order to be sure the machine is in working condition.
Preset the necessary rev with the switch (Fig.4.12-7) and the speed with the switch

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. Avoid
vibrations. Do not stop the machine in one spot while the tools are still working because they will leave marks on the floor
surface. When working wet, begin with the water tap, (Fig.4.2-1) position for the water feed and periodically start the
pump (Fig 4.12-11) to release water onto the floor surface. Starting the pump is only possible if the machine motor is on.
When working dry, check the floor surface periodically to ensure that dust is not accumulating on it. Regularly check to
make sure the vacuum works properly. In any case you may turn on the lights (Fig.4.12-5).
STOPPING THE MACHINE
The machine can stop by switching the joystick in opposite position of the moving direction.
The movement of the machine should only be stopped then the motor has completely stopped. Do not stop moving the
machine before stopping the motor rotation, otherwise it could damage the surface.
In order to stop the machine’s motor, use the “motor off” switch (Fig.4.12-1). Only use the “Emergency stop button” in an
emergency!
NOTE! Do not hold the machine in one spot until the motor completely stops turning!
ALARM
The machine stops when the emergency stop button is activated or the inverters are shut down by emergency. It
is indicated by a flickering lamp built into the switch “BATTERY-LINE".
The control panel display will show "Emergency stop" or "Inverter fault". After eliminating the accident, reset the
machine by releasing the emergency stop or turning on the "Inverter reset" ( Fig.4.12-3).

8. MAINTENANCE AND INSPECTION
CLEANING
Keep your machine clean. Cleaning the machine on a regular basis will help detect and solve potential problems before they
cause damage to the machine. Most importantly, check and clean the tool plate connections, power cord and plugs, vacuum
hoses and water tank.
CHECK DAILY
After operating the Lavina® 32R-S/32R-S-HV, the operator should conduct a
visual inspection of the machine. Any defect should be solved immediately. Pay
attention to power cords, plugs and vacuum hoses loose bolt or screws.
Tool holders: Buffers and spiders are consumables and must be visually checked on a
daily basis and replaced if needed. The key lock holders (butterflies) on the tool
holders should be also checked.
Check the rubber buffers and make sure the holders are secure. The flange holding the
buffers (Fig.8.1-1)has to be firmly secured to the unit If there is a gap here, then the
screws securing the holder are loose. The screws have to be tightened immediately in
order to safely operate the machine. Working with loose screws can also cause serious
damage to the machine. The tightening force of the screws has to be 25-30N.m (18-22
ft/lbs).
It is very important to regularly check the screws (Fig.8.1, 2),that fix the
"QuickChange" holder to the safety part, so that holder will not fly away if the buffers
get damaged.
“Quickchange” should be clean. The tension of the planetary belt can be checked by
moving the main head and feeling the resistance of the moving pulleys, tighten the belt if necessary (Chapter:
Troubleshooting).
CHECK AFTER THE FIRST 15 WORKING HOURS
The low cover has a control cover (Fig. 9.4) that allows fast and easy control and correction of the belt. It is
recommended to check the tension of the belt after the first 15 hours and to tighten if necessary. For the correct tension,
see TROUBLESHOOTING “mounting the belt”.
CHECK EVERY 200 WORKING HOURS
Every 200 working hours, the operator should inspect all parts of the machine carefully. Most importantly, inspect and
clean the tool plate connections, power cord and plugs, vacuum hoses and water tank and filter. Also, check the water
flow of the pump. Check the guard assembly. Make certain the wheels are clean and rotate properly. Inspect the control
buttons. If there are defective control parts, they should be replaced immediately. Replace worn vacuum - and water
hoses. Check the tension of the belt and to tighten if necessary. For the correct tension, see TROUBLE SHOOTING.
Carefully inspect the seal rings and bearings of the grinding units, and replace any showing signs of excessive wear.
For more information, refer to chapter troubleshooting below.
CHECK EVERY 400 WORKING HOURS
Besides the checks after 200 working hours, open up the bottom cover like described in the chapter “TROUBLE
SHOOTING REPLACING BELT TENSIONING.” Check if sealers, belt, and bearings are in good condition, change if
needed. Beware when tensioning the belt, not to “over tension”, because the belt will never regain his original tension.
VACUUM
As previously stated, frequently check hoses and other parts for clogging.
WATER LEAKS
Leaking parts should be replaced immediately, because the water could damage your machine.
ELECTRICAL SYSTEM
Dust should not enter the control box, as it will destroy the contacts. Remove (blow out) any dust present.
MECHANICAL PARTS
Parts such as the belt, seal rings, cap rings, spiders, buffers, and guard assembly are subject to wear and should be
replaced as needed.
CARRIAGE WHEELS
Check the pressure of the pneumatic tires and maintain it at the limits of 3.5-4 atm/50...60PSI/.

BATTERY OF THE DRIVING
The machine uses maintenance free battery. The battery charges
automatically during work. After long transportation on self move the
machine should be switched on to the power supply and the power switch
BATTERY-LINE to stay on LINE position, in order to recharge the battery.
The approximate battery charge level can be checked on the Indicator
Lights that is noted in the operating manual of the control box built-in DC-
to-AC Inverter/Chargers.
Upon long outage of the machine (more than one week) it is
recommended to switch off the battery of the system by the safety switch
on the bottom part of the board (Fig.8.2) or to unplug the battery cables.
BATERRY OF THE PANEL
The condition of the panel battery is displayed on the right upper corner of the screen. In case the batteries are run
down they should be changed or the panel to be connected with the cable (see.Fig.4.8; Fig.4.9; Fig.4.10), then the
baterries start to recharge.
