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®32M-X-HV machine is intended for grinding, polishing and buffing concrete, marble, granite, limestone and
terrazzo surfaces with diamond tools.
The Lavina®32M-X-HV is a self-propelled six-disc machine 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®32M-X-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®32M-X-HV is made of two main component
sections:
LAVINA®32M-X-HV MAIN DESIGN
The two main component sections, the carriage and main
head.
The wheels of the carriage are driven by one gear box that allows working with the machine
without continuous guiding from the operator. The handle on the frame is adjustable in height
and enables the operator to work in a correct and safe posture.
Two halogen spotlights (Fig.1.2) enable the operator to work in darker areas. The lamp holder can be adjusted in
different positions.
Existing lighting system does not replace adequate overhead
lighting.
The controls are positioned on top of the handle (fig.1.3)
The electrical box contains the electric switching
devices and inverters. The motor feeding cable is
plugged in 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
(fig.1.4).
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 from the tank is supplied by a
pump. The frame weight, on the other hand, is fully absorbed by the driving wheels.
The working part motor is mounted on the base plate and the six grinding heads are
driven by a two-belt system. The planetary head is driven by a duplex roller chain.

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®32M-X-HV .
CONTROL OF THE WATERFLOW
Using the valve (Fig.4.2-2) the operator can choose from where the water to spray:
- when the handle of the tap is in vertical position the water will spray in front of the machine (fig.4.1),
- when the handle is in the horizontal position the water will spray under the cover of the machine.
The flow regulating valve located on the tank (Fig.4.3) is increasing or reducing the waterflow to the working
area – in front of the machine or under the main head cover of the machine.
The valves (Fig. 4.2-1 and Fig. 4.2-3) are controlling the flow of an external water supply. A ¾” water tube can
be attached to the quick connection (Fig. 4.2-4).
ADJUSTING AND MOUNTING TOOLS
The Holder A41 in LAVINA® X can work with either
3 or 6 buffers which will change its elasticity. You
can make the change after dismounting the holder
as per the instruction in TROUBLESHOOTING.
In Lavina 32M-X-HV the holder is initially
mounted with 6 buffers.
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: Secure always the“Quickchange” pads with the security
plate (Fig.4.5), lock with the tool holder key (Fig.5.3). Diamond tools with Velcro are attached on six foam
plates of 9 inch(Fig.4.6). The foam plates are mounted on the key lock (butterfly).Always use the tool holder
key (Fig.5.3).
The machine can work with 3 operating heads only when each working heads alternate with not working
head. It is recommended to dismount the not working holders /only holders, not adaptors / because there is a
possibility to wear out the seats of the tool fixing. In that case screw the bolts
fixing the holders in the free thread holes of the adaptors in order to protect
them./fig.4.7/

from the Emergency stop button. It must be used when operating the machine on a slope for the security of
the operator and the machine. Disconnecting the connection between the gearmotor and the carriage
wheels is possible after switching the button in position OFF and activating the button STOP /pos9/.
STARTING THE MACHINE
Follow strictly the instructions in chapter "SAFETY INSTRUCTOINS".
NEVER WORK WITH THE MACHINE WITHOUT VISUAL CONTACT WITH IT.
First, follow the directions in chapter Safety Devices and Safety Instructions. If working wet, add water
to the floor surface. If working dry, omit this step, and instead, switch on the vacuum unit. Next, pull the
emergency stop (Fig.4.8 1) to ensure that the machine is in working condition. Check the potentiometer
(Fig.4.8 3) and ensure that it is set at the working speed. Check the potentiometer (Fig.4.8 9) for the required
working speed.
Finally, hold the machine firmly and turn the start button (Fig.4.8 6) and set movement direction of the machine
– forward or backward from the corresponding buttons (Fig.4.8 12 and Fig.4.8 13).
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.
At the end of each line you can reverse the direction of the machine by simply pressing the
corresponding button FORWARD or BACK and through the handles to direct a new runway. If you get tight
the handles and trigger the button STOP you will get to manual operated mode of the machine and can
performe more complicated maneuvers. Once you direct the machine in the desired direction activate again
the selfpropelled movement. Increase or decrease of the speed of the machine when operating can be made
by the potentiometer (Fig.4.7-9)
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 Lavina®32M-X-HV machine in one spot while the tools are still working
because they will leave marks on the floor surface. When working wet, preliminary chose with the water tap
(Fig.4.2-1) the position for water feed and periodically start the pump (Fig 4.8-8) 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 check regularly if your vacuum works properly.

Figure 5.8
If you need to process on the floor with a slope that requires significant effort to work with machine
with manual control, put the button SLOPE in position ON. In this position the activating the button STOP or
Emergency stop will not disconnect wheels and motorgear connection and it will serve as a break on any
movement of the machine on the slope. In that case the machine is operated by the buttons FORWARD ;
BACK and STOP, but without possibility to go to manual control and at the end of the coarse. To switch to
manual operation and control of the machine get the button SLOPE in position OFF and push the button
STOP.
STOPPING THE MACHINE
The stopping of the machine must be done gradually until the motor stops. Do not stop moving the
machine before arresting the motor as the tools could damage the surface. To stop switch the off switch
(Fig.4.8-6). Use the Emergency button (Fig.4.8-1) only in emergency or use it to switch the power totally off.
Remember not to hold the machine in one spot before turning off the motor.
The machine drive is stopped by the button STOP (Fig.4.8-10) or Emergency button (Fig.4.8-1)
ALARM
The Alarm light ((Fig.4.8 4) will light incase inverter goes in alarm mode. The most common failure is motor in
overload. To reset the mode push reset button ((Fig.4.8 5).
5.TOOLS AND ACCESSORIES

7. 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® 32M-X-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 elastic element are consumables and must be visually
checked daily and replaced if needed. The key lock holders (butterflies) on the
tool holders should be also checked.
Check the rubber buffers and fixing of the holders. The flange holding
the buffers (Fig.7.1-1)has to be firmly fixed to the unit. A gap seen there
means that there are loose screws fixing the holder. The screws has to be
tightened immediately for safety operation.Working with loose screws on the
holder could also cause bad damages on the machine. Tightening force of the
screws has to 22...25 N.m(16...18 ft/lbs).
It is very important to check regularly the screws(Fig.7.1 2),that fix the
"Quickchange" holder to the safety part, so that holder will not fly away if the
buffers got damaged.
“Quickchange” should be clean.
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. Open the service cover on the motor base to check of
the planetary chain. Lubricate the chain with special lubricant for chains and correct the sag if needed.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 of 200 working hours Check if sealers and bearings are in good condition, change if
needed.
VACUUM
As stated previously, frequently check hoses and other parts for clogging.
WATER LEAKS
Replace any leaking parts immediately as 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 and buffers and guard assembly are subject to wear and
should be replaced as needed.
CARRIAGE
Check the pressure of the pneumatic tires and maintain it at the limits of 3.5-4 atm/50...60PSI/.
Check the seal rings on the driving unit and promptly replace in case of damage.

8.4 TENSIONING USED PLANETARY CHAIN
Take out the support frame of the weights(Fig.8.4.1_2) by releasing the fixing pins (Fig.8.4.1_1). Unscrew the 6 bolts
and take out the front part of the cover (Fig.8.4.1_3), (not necessary to take out the hose from the sprayer. Lift the
machine in position to change the tools. Turn manually the holders in order to turn the main head, stop when you see
through the window the chain link and the chain tensioner.(Fig.8.4.3)
Loosen a quarter to 1/2 rev the two bolts of the chain tensioner (Fig.8.4.2_4); the tensioner should turn with minimum
clearence, without inclination, then unscrew the inner nut (Fig.8.4.3_5) To tension the chain screw the outer nut
(Fig.8.4.3). tensioner of the planetary chain should allow chain sagging 3...5mm/1/8...3/16 in/ controlled in span X
(Fig.8.4.5). When ready screw the two nuts (Fig.8.4.3-5) and two bolts (Fig.8.4.2_4).
8.4 MOUNTING AND TENSIONING A NEW PLANETARY CHAIN
The planetary chain is replaced with new one when the step/drive? of the chain tensioner is finished or there is a break
in the integrity of the chain. Take out the weight support (Fig.8.4.1), release the connector of the motor and separate
the carriage from the main head. Take the main head of the carriage, like described in the paragraph “Splitting the
carriage from the main head”, Dismount the top cover.
Pull out the split pin (Fig.8.4.1) and the chain link pin (Fig.8.4.2). Put on the same way the new chain, get in the chain
link pin(Fig.8.8.5) (Fig.8.8.6) and the split pin (Fig.8.4.4).
To tension the chain screw the outer nut (Fig.8.4.5_3) . The tensioner of the planetary chain should allow chain
sagging 3...5mm/1/8...3/16 in/ controlled in span X (Fig.8.4.5). When ready screw the two nuts ((Fig.8.4.5_2) and two
bolts ( Fig.8.4.5_3).
ATTENTION: NEVER “OVER” TENSION THE CHAIN,
THE CHAIN WILL BE DAMAGED .

8.5 TENSIONING AND REPLACING THE BELTS
The transmission of the machine has two timing belts of maintenance free type. To change the belts you have to
remove all holders and dismount their adaptors. Dismount the sealing. Carefully check the friction surface (flanges of
the lower cover and the outside diameter of the adaptors). Decide if they are in good condition (wear out, smoothness
of surface) and whether they can work until next inspection. Remove the bottom cover, unscrew the bolts on the
outskirt and the three bolts of spacer ( Fig. 8.5.1). Under the cover on the outskirt there is e sealer, and the spacers
have O-Rings. The change of all seals together with the belts is recommended.
Fig. 8.5.4 shows the scheme of belts location. To mount the
new belts first unscrew nuts on pos.7; pos.8 and pos.9, as far
as to be able to turn the tensioners pos.4, pos.5 around
central axle. Clean the washers and space around, and check
if all bearings of pulley units or tensioners are in good
condition (check for too much clearance or rolling noise).
Rotating the tensioner will allow the centre distance to be
reduced in such a way that the timing belt may be fitted
without force.
Installation with the use of force is NOT permissible
at any time as this can damage the high quality, low stretch
tension cord and other components. This damage is often not
visible.
Put the belts in pos.10 as per the scheme, and pay
attention for their correct position in every pulley. Screw up
until it stops and loosen on the half moons the nuts pos.8,
allowing the rotation of the tensioners at minimum inclination.
Using nuts on pos.7 tighten the belt, verifying again the
correct position of the two belts, and the correct gearing in
every pulley. Rotate the gear while tensioning to allow regular
tension distribution on the belt. Control the tension using
Frequency tension Tester (Optibelt 3 TT) (Fig. 8.5.3). Tension
in the span Аof the belt should be 115-120Hz.
It is possible for tensioning the belt while changing it
to use the pre-installed supports (Fig.8.5-11) (only when their
factory position is not changed), to limit the turn of the tensioner when the required belt tension is done.
8.6 REPLACING THE PULLEYS
Take the belt tension away (see the previous paragraph).
After removing the belts, unscrew the four bolts of the
pulleys on top of the disc (Fig. 8.6.1).
