4.3 ADJUSTING AND MOUNTING TOOLS
Lavina® 25REU uses tool holder A63. With this new holder every one of our tools uses the “Quickchange” connection. To change the
tools you need first to unlock the butterfly (fig 4.6 in blue) by using the key we provide you (you can see it in the pictures fig. 4.7)
remove the security plate (fig 4.6 in red) then load the tools you want and insert the security plate again so the tools cannot go
backwards, rotate and lock the butterfly (as shown in fig.4.7). As you can see in fig. 4.6, for some of the new tools you need to
remove the security plate as they don’t need locking system at all but for the others always make sure that the tools are securely
locked.
In Lavina 25REU Elite the holder is initially mounted with 3 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: Always secure the Quick Change tools with the butterfly (Fig.4.6 in blue), lock with the tool holder key
(Fig.4.7) and make sure that the butterfly is securely locked and it holds the security plate not to fall off.
4.4 VACUUM CONNECTION

4.8 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 the tools’ 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, select the destination of the water feed with the water tap (fig. 4.2) and periodically run the pump to release water
onto the floor surface. Starting the pump is possible only if the machine motor is on. When working dry, check the floor
surface periodically for dust accumulation. Check regularly to see if you’re vacuum works properly.
4.9 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.Push the STOP button (3) .
2.Turn the ON/OFF (10) switch in position OFF, this will cut the voltage to the invertor and the green light will turn off.
The machine turns OFF automatically after 20 min of not using the PORTABLE DEVICE.
NOTE! Do not hold the machine in one spot before the engine stops to turn.

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 can cause
damage to the machine. Most importantly, check and clean the tool plate connections, power cords, plugs, vacuum hoses, and water
tank.
CHECK DAILY
After operating the Lavina® Elite machine, the operator should conduct a visual inspection of the
machine. Any defect should be solved immediately. Pay attention to power cords, plugs, vacuum
hoses, loose bolts or screws.
Tool holders: Buffers and elastic element are consumables and must be visually checked on a daily
basis and replaced if necessary. Make sure the flanges or discs are securely locked in place. The key
lock holders (butterflies) should also be checked.
Check the rubber buffers and make sure the holders are secure. The flange holding the buffers
(Fig.7.1‐1) has to be firmly secured to the unit. If there is a gap seen here, that means the screws
securing the holder are loose. The screws have to be tightened immediately to safely operate the
machine. Working with loose screws could cause serious damage to the machine. The tightening force
of the screws has to be 22‐25N.m (16‐18ft∙lbf).
It is very important to regularly check the screws that secure the “QuickChange” holder to the Figure
7.1 safety part (Fig.7.1‐ 2), so that the holder will not fly away if the buffers get damaged. The
“QuickChange” should also be cleaned.
.
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 plugs, vacuum hoses and water tank/filter. Also, check the water flow of the
pump. Check the guard assembly. Ensure the wheels are clean and rotate properly.
Inspect the control
buttons. If there are defective control parts, they should be replaced immediately.
Replace any worn vacuum or water hoses.
Open the service cover on the motor base (Fig 7.2) (Fig 7.3) to check the
planetary chain. Lubricate the chain with chain lubricant and correct the sag if
needed. (For sagging correction see TROUBLESHOOTING 8.4)
Dismount the tool holders (See TROUBLESHOOTING) and replace any parts
(elastic element, buffers, sealer caps, “O” rings) showing any damage.
CHECK EVERY 400 WORKING HOURS
In addition to checks made every 200 working hours, replace sealer and V‐rings as
described in chapter “TROUBLESHOOTING ‐ DISMOUNTING TOOL HOLDERS TO CHANGING V‐RINGS AND FELT‐RINGS.
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.

INDEX OF PROBLEMS AND SOLUTIONS
8.1 SEPARATING THE HEAD FROM THE CARRIAGE
1. Unscrew the four bolts to remove the panel fig. 8.2-1.
2. Disconnect the cable of lamp and remove the lamp fig. 8.2-3.
3. Disconnect the flexible hose under the panel fig. 8.2-2. All water connections in the machines are with fitting types
“Push-in” and “Release button”.
4. Unscrew the four bolts to remove the cover fig. 8.2-4.
5. Disconnect the flexible hose which comes from the pump fig. 8.2-5.
6. Disconnect the engine cable from the power box fig. 8.2-6.
7. Release the clamp and remove the suction hose from the head fig. 8.2-7.
8. Make sure everything is disconnected fig. 8.2-8.
9. For separating the carriage from the head you need to be two people –one to hold the carriage while the other
removes the pins fig 8.2-9. After the pins are removed the person which is holding the carriage should carefully place it
on the ground without harming it fig. 8.1.

8.2 DISMOUNTING/MOUNTING THE
GUARD
You can dismount and mount the safe
guard without separating the carriage from
the main head. Put the machine in position
to change the tools. Unscrew the four bolts
M5 from the metal cover preventing the
safe guard to fall. Dismount one of the
three holders. Dismount the safe guard.
8.1 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. Do
not use lower quality or different types of cords or plugs.
In addition, consider the distance between the appliance and the electrical source. The greater the distance, the greater the resistance and
the less current that will be available at the other end. This will cause a voltage drop and the inverter will switch into alarm mode. This will
also happen if several machines are working on the same line or the generator is not rated for the power needed. In general, our standard
power cable can be doubled in length; longer lengths require replacing all the cables with cables of a larger gauge rate to account for the
length and amperage.
8.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGING V-RINGS AND FELT-RINGS
To check or replace the buffers and the elastic elements, the tool holders have to be dismounted.
You will need a 13mm deep metric socket with an outside diameter of no more than 3/4in to unscrew the four bolts (Fig.8.2.1) and remove
the holder (Fig.8.2.2). When the tool holder is dismounted, you can change the sealers (V‐Ring and Felt‐Ring).
By loosening four Hex cap flange bolts (Fig.8.2.3) the adaptor comes loose. Unscrew the six screws of the cap (Fig.8.2.4) holding the felt‐
ring. Take out the Felt‐Ring, adaptor and V‐Ring.
Mount the V‐Ring with the smallest lip of the V to the inside (Fig.8.2.5) ‐ simply push the V‐Ring so the top is on the same level as the
pulley top (Fig.8.2.6). Then take the adaptor and push the V‐Ring down with the adaptor (Fig.8.2.7). The lowest lip of the V‐Ring should only
barely touch its gliding surface. Mount the adaptor and the Felt‐Ring on top (Fig.8.2.7). Close the sealers with the cap (Fig.8.2.8) and screw
the bolts. Always use the original bolts. Do not push the V‐ring down with fingers.
