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-E 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.
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).

and fix again.
RELEASINGING THE WHEELS OF THE CARRIAGE
If for some reason the movement of the machine is not possible with its own battery (using the third wheel), it can be done on the
two wheels of the carriage by the operator. Each of the wheels can be released from gearing to the driven 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.

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.4.5). 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 while 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.

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
(Fig.4.12-8).
Then start the motor by switching “Motor on" (Fig.4.12-10) and preset movement direction from the joystick
(Fig.4.12-6), by holding up the joystick for 1second in final position of the desired direction.

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 bolts,
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.
The “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 controls. 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.

9. TROUBLESHOOTING
INDEX OF PROBLEMS AND SOLUTIONS
9.1 REPLACING POWER CORD AND PLUGS
When replacing the power cord or plugs always use cords and plugs with the same specifications as the
original ones. Never use lower quality or different types of cords and plugs.
9.2 DISMOUNTING AND MOUNTING TOOL HOLDER
TO CHANGE BUFFERS AND SPIDERS, CHANGING V-RINGS AND FELT-RINGS
To check or replace the buffers and the spiders, the tool holders have to be removed. Remove the countersunk screws
on top of the buffer (Fig.9.2.1). Take the disc off (Fig.9.2.2), now the spider can be removed or replaced (Fig.9.2.3). By
loosening the four Hex cap bolts (Fig.9.2.4), the disc comes loose (Fig.9.2.5) and the buffers can be replaced
(Fig.9.2.6). Attention, when mounting always use, the “blue” thread locking adhesive, except on the bolts to lock the
buffers (Fig.9.2.5). Always use original bolts.
Depending on the number (3, 4, or 6) of buffers, the holder can be more flexible or rigid.
When the tool holder is dismounted, you can change the sealers (V-Ring and Felt-Ring).
Take out Felt-Ring, Adaptor and V-Ring. Before mounting check on which side the
adaptor is fitting, remember the correct side. Mount the V-Ring with the smallest lip of
the V to inside (Fig.9.2.7) just push the V-ring so the top is on the same level as the
pulley top (Fig.9.2.8). Than take the adaptor in the correct way and push the V-Ring
down with the adaptor (Fig.9.2.9). The lowest lip of the V-Ring should only barely touch
its gliding surface; also never push the V-Ring down with fingers. Mount now the Felt-
ring on top (Fig.9.2.10). Close the sealers with the cap (Fig.9.2.11).
