1. GENERAL INFORMATION
This owner’s manual is intended for the operator of the Lavina® S 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® S 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® S machine is intended for grinding, polishing and buffing concrete, marble, granite, limestone and terrazzo surfaces
with diamond tools.
The Lavina® S machine is a three‐disc machine, which can be used dry as well as wet.
For best results, use only tools manufactured or recommended by Superabrasive and its distributors. Additionally, the machine could
be used for grinding wood floor surfaces.
The Lavina® S machine is manufactured and fitted for the above‐
mentioned applications only! Every other use may cause risks to the persons involved.
MACHINE CHARACTERISTICS
The Lavina® S machine is made of two main component sections:
MAIN DESIGN
The two main component sections are the carriage and main head.
The handle (Fig.1.2) on the frame can be adjusted by height and allows the operator to work in
a correct and safe working posture.
The halogen spotlight (Fig.1.2) enables the operator to work in darker areas.
Existing lighting system does not replace adequate overhead lighting.

Figure 1.1

The frame
The controls are positioned on top of the electrical box (fig.1.3)
The electrical box (fig.1.3) contains the electric switching devices and the
inverter. The main feeding cable is connected with a plug and socket on top. The motor
feeding cable is plugged into the socket located on the bottom of the box. The 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. An
electric pump sprays the water through a front sprayer. The motor is mounted on the base
plate and is driving 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 Lavina® S machine outdoors is between 41°F and 86°F
or 5°C and 30°C. Never use the Lavina® S machine during rain or snow when working outdoors.
When working indoors, always operate the machine in well‐ventilated areas.

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® S machine, 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 daily and
replaced if needed. See that flanges or discs are mounted and locked well in place. The
key lock holders (butterflies) should be also checked.
Check the rubber buffers and fixing of the holders. The flange holding the buffers (Fig.8.1
1) has to be firmly fixed to the unit. A gap seen there means that there are loose screws
fixing the holder. The screws have to be tightened immediately for safe operation.
Working with loose screws on the holder could also cause bad damages on the machine.
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 the holder will not fly away if the buffers
Figure 8.1
get damaged.
“Quickchange” should be clean. The tension of the planetary belt can be checked daily by moving the main head and feeling the
resistance of the moving pulleys, if the belt slips tension immediately, see the chapter Troubleshooting .
CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours working with the machine.
The bottom cover has a control cover (Fig.8.2) 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”.
Every time you open the control cover, mount back all the screws.
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
Figure 8.2
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 TROUBLESHOOTING.
Dismount the tool holders (See Troubleshooting) replace all parts (Spider, buffers, sealer caps, “O” rings) with the slightest
damage or consume.
Open the inspection cover on the motor base to check the planetary driving belt, by moving the main head the belt should not slip
on the planetary pulley and drive the pulleys.
CHECK EVERY 400 WORKING HOURS
Besides the checks of 200 working hours, replace sealer and V‐rings like described in chapter “TROUBLESHOOTING REPLACING
BELT AND PULLEY UNITS”. Check if belts 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
MECHANICAL PARTS
Parts such as the belts, seal rings, cap rings, spiders and buffers and guard assembly are subject to wear and should be replaced as
needed.
ELECTRICAL SYSTEM
Dust should not enter the control box, as it will destroy the contacts. Remove (blow out) any dust present.
The Lavina® 20N‐S 200‐240 Volt will automatically detect if the connection is based on single (L1, L2) or three phase (L1, L2, L3)
208‐240 Volt. The operator does not have to switch the machine; only connect to two phases or three phases. For convenience,

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 specifications as the original ones.
Never use lower quality or different type cord and plugs.
In addition, take into consideration is the distance of the appliance from the electrical source. The greater the distance, the
greater the resistance and the less current that will be available at the other end, there will be a voltage drop and the inverter will
sign alarm mode. This also happen if several machines are working on the same line or when the generator is underrated. In general
our standard power cable can be doubled in length, if longer lengths needed you have replace all the cables with cables with bigger
gage rated for the length and amperage.
9.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND SPIDERS, CHANGING V‐RINGS AND FELT‐RINGS

Figure 9.2.1

Figure 9.2.3

Figure 9.2.2

Figure 9.2.4

Figure 9.2.6

Figure 9.2.5

To check or replace the buffers and the spiders, the tool holders have to be dismounted. Remove the countersunk screws on top of
the buffer (Fig.9.2.1). Take the disc off (Fig.9.2.2), the spider can be removed or replaced (Fig.9.2.3). By loosening 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, by mounting use always the
“blue” thread locking adhesive, except on the bolts to lock the buffers (Fig.9.2.5). Always use the original bolts.
Depending on the number (3, 4 or 6) of buffers, the holder can be more flexible or rigid.

Figure 9.2.7

Figure 9.2.8

Figure 9.2.10

Figure 9.2.9

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). Then
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).

The mounting of the belt is shown on Fig. 9.7.11. Putting the belt
is possible when the tensioner is in starting position:
‐ loosen the nuts pos.2
‐ loosen enough the nuts pos.3 (or unscrew them).
‐ unscrew the nut (pos.4) and pull out the bush (pos.5) from hole
D in the tensioner (pos.1), that will allow the tensioner to have the position
in Fig. 9.7.11.
‐ put the belt following steps shown on Fig. 9.7.2; Fig. 9.7.3 and
Fig. 9.7.4. (It is possible also to put the belt on the roller unit assembly as a
last step.) Check if the belt is on the right place in the grooves of each of
the pulley units and on the central pulley.
Put back the tensioner in a position the axle bushing to fit in the
tensioner hole (Fig. 9.7.5) (You can push down the bush screwing the nut
pos.4)
Tighten the nuts (pos.2, Fig. 9.7.1) on the sectors and unscrew half
