4.3 ADJUSTING AND MOUNTING TOOLS
Lavina® 25LEU 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.

4.7 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.

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®E 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
7.1
“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 othe r 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.
8.3 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.
8.4 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.8.4.1) and remove the holder (Fig.8.4.2). When the tool holder is dismounted, you can change the sealers (V‐Ring and Felt‐Ring). By loosening four Hex cap flange bolts (Fig.8.4.3) the adaptor comes loose. Unscrew the six screws of the cap (Fig.8.4.4) 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.8.4.5) ‐ 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.8.4.7). The lowest lip of the V‐Ring should only barely touch its gliding surface. Mount the adaptor and the Felt‐Ring on top (Fig.8.4.7). Close the sealers with the cap (Fig.8.4.8) and screw the bolts. Always use the original bolts. Do not push the V‐ring down with fingers.

8.5 DISASSEMBLING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND ELASTIC ELEMENT
When the TOOL HOLDER is disassembled you can change defective parts – elastic element, buffers, etc.
Lift the locking pin (Fig.8.5.1) to dismount the retaining washer (Fig.8.5.2). Take out the screws on the buffers and the nuts of the elastic element (Fig.8.5.3;Fig.8.5.4). Remove the elastic element from the QC plate (Fig.8.5.5). While the holder is dismounted (Fig.8.5.6;Fig.8.5.7), clean the parts and replace any defective ones with new ones. Assemble the holder with new buffers, new screws, and new elastic element. Replace the retaining washer (Fig.8.5.8) and push the locking pin (Fig.8.5.9). This will prevent the washer from falling while mounting the holder on the machine.
Make sure the four bolts holding the adaptor (Fig.8.5.12) are reliably tighten. Mount the holder on the machine using the same socket as mentioned in 8.2 (Fig.8.5.10;Fig.8.5.11). The retaining washer fits into the central hole C of adaptor and the four bolts into the thread holes Т (Fig.8.5.12). The holder is centered on the outside diameter of the adaptor. Ensure the holder is properly connected to the plate of the adaptor and then tight evenly the four bolts.Tightening force of the bolts has to be
22...25N.m(16...18 ft/lbs). Mounting the holder without retaining washer (Fig.8.5.2) is INADMISSIBLE because the security system preventing the separation of part of the holder in case of broken buffers and elastic element will not function!You can change the butterfly of the holder without dismounting the holder of the machine.
You can change the butterfly of the holder without dismounting the holder of the machine. Fig.8.5.13 is a 3‐
D section view of the holder, showing its parts. The numbering is the same as in Spare parts.

8.6 CORRECTING DEFLECTION OF THE USED PLANETARY CHAIN
Unscrew the bolts and take out the cover (Fig.8.6.1). 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 tensioner (Fig.8.6.2).
Loosen a quarter to 1/2 rev the two bolts of the chain tensioner (Fig.8.6.3) the tensioner should turn with minimum clearence, without inclination, then unscrew the inner nut. To
tension the chain screw the outer nut (Fig.8.6.4). The tensioner of the planetary chain should allow chain sagging 3...5mm/1/8...3/16 in/ controlled in span X (Fig.8.6.5). When ready screw the two nuts (Fig.8.6.4) and the screw(Fig.8.6.3).
ATTENTION: NEVER “OVER” TENSION THE CHAIN, THE CHAIN WILL BE DAMAGED
MOUNTING 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. Unscrew the bolts (Fig.8.6.1) and take out the cover. 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 tensioner
(Fig.8.6.2). Separate the carriage from main head, point 8.4 , pull out motor plug, water tubes and vacuum tubes. Take off handle (without water tubes). Release the pin sets which attach the head to the carriage. Take off the service window (Fig. 8.6.1) so you can dismount the top cover
Loosen the two nuts(Fig.8.6.4) and uscrew the two screws of the tensioner (Fig.8.6.8)(Fig.8.6.9)(Fig.8.6.10). Take the chain tensioner(Fig.8.6.11). Pull out the split pin (Fig.8.6.12) and the chain link pin (Fig.8.9.8) (Fig.8.6.13). Take the chain, and put on the same way the new chain, get in the chain link pin and the split pin (Fig.8.6.13) (Fig.8.6.12) (Fig.8.6.11).

The tensioner should turn with minimum clearance, without inclination. Then unscrew the inner nut. To tension the chain, rotate the outer nut (Fig.8.6.4) . The tension of the planetary chain should allow chain sagging of 3...5mm (1/8...3/16 in) measured in span X (Fig.8.6.5).
When properly tensioned, retighten the two nuts (Fig.8.6.4) and the screw(Fig.8.6.9).
ATTENTION: NEVER “OVER” TENSION THE CHAIN, THE CHAIN WILL BE DAMAGED
8.7 REPLACING THE PLANETARY DRIVING CHAIN WHEEL AND PLANETARY TENSIONER
Check and repeat the instructions in 8.5 MOUNTING NEW
PLANETARY CHAIN.
Unscrew bolt (1) and remove the chain pulley (3) with the sealer (5). Change the sealer, and mount it to the chain pulley (3). Apply lithium grease on the shaft and mount back the wheel and the front washer (2) as shown on (Fig.8.7.1). Screw the bolt using the “blue” thread locking adhesive. Tightening force on the bolts should be
9...11N.m(6.6...8 ft∙lbf).

8.8 TENSIONING AND REPLACING THE BELTS
The transmission of the machine runs two timing belts (a main belt that
rotates the plates (and tools) and an auxiliary planetary belt which propels the rotation of the head as a whole). To change the main belt, remove all plate holders and adapters. There will be a seal to remove as well. Check any friction surfaces for wear, and replace if necessary. To remove the bottom cover, unscrew the bolts at the circumference of the cover, as well as those in the spacers. We recommend that all seals (O‐Rings in the pacers and seal around the cover) be replaced when changing belts. Figure 8.8.4 shows the scheme of the belts. To remove the old bels first remove the planetary belt (1) and then the main belt (6). To remove the main belt (6), loosen nuts (4) and (5) enough to be able to turn the tensioners (3) around the central axle. Clean the washers and surrounding area, and check all bearings of pulley units/tensioners for too much clearance or rolling noise. Rotating the tensioner will allow the centre distance to be reduced in such 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. Arrange the belts in pos.6 as per the scheme, paying attention to their orientation at every pulley. Loosen the nuts (5) to the end of the bolt, and fully loosen the nuts on the
half moon (4), allowing the rotation of the tensioners with minimal force.
Using nuts (5), tighten the belt, double checking the position/orientation of the belt and the gearing in each pulley.
Rotate the gear while tensioning to allow regular distribution of tension along the belt.
Measure the tension using a Frequency Tension Tester (Optibelt 3 TT) (Fig. 8.8.3). Tension in
span “А” of the belt should be 120‐130Hz. It is possible to use the pre‐installed support (Fig.
8.8.4‐2)(Fig. 8.8.5) as a reference to stop the tensioner at the desired belt tension, provided that the supports have not been moved from their factory position.
ATTENTION:NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DESTROYED AND IT WILL NEVER RECOVER ITS ORIGINAL TENSION
To remove the planetary belt (Fig.8.8.4‐1), unscrew the screw of the front washer (Fig.8.8.6) and the two screws of the conical sleeve (Fig.8.8.7). Screw one of the removed screws into the free thread(Fig.8.8.8) to push the washer down (Fig.8.8.9); take off the conical sleeve and the belt (Fig.8.8.10).

The reassembly is the same process in reverse. It is important to match the threads of the conical sleeve and the belt washer(Fig.8.8.11). Put the front washer (Fig.8.8.12), on the screw ‐
using “blue” thread locking adhesive.
Tightening force of the bolts has to be 4,5...6N.m(3,3...4,4 ft/lbs). Carefully replace the two binder screws while leaving the central thread open.(Fig.8.8.12)(Fig.8.8.13). Insert the screws by alternating at 1.5 revolution each until the conical sleeve pulls up the belt pulley. The conical sleeve must be aligned in height with the belt washer(Fig.8.8.14).
Dismounting the planetary belt is possible without removing of the Bottom cover assembly by unscrewing the eight bolts and removing the service window cover and the sealing(Fig.8.8.15)(Fig.8.8.16)
to access the planetary belt (see 8.8.17)

Remove the planetary chain and tensioner (see 8.6 ‐ MOUNTING NEW PLANETARY CHAIN). Dismount the tool holders, sealers, and bottom cover (TENSIONING AND REPLACING THE BELTS). Unscrew the cap to access the fastening bolts of the driven gear (Fig.8.9.1)(Fig.8.9.2). Rotate the main head such that you see a fastening bolt of the gear (Fig.8.9.3) through the hole. You will need a 10mm magnetic deep metric socket with an outside diameter of no more than 11/16 in to unscrew the six bolts (Fig.8.9.3)(Fig.8.9.4) (Fig.8.9.5). Once these are removed, remove the two halves of the gear. The gear is composed of two symmetrical halves(Fig.8.9.6). Mount them in reverse order.
8.10 REPLACING THE PULLEY UNITS
Dismount guard, top cover, maintenance window chain tensioner, driven chain wheel, bottom cover and belts as previous
described.
Unscrew the four bolts of each pulley between the base plate and the motor base disc (Fig.8.10.1)(Fig.8.10.2) and dismount the pulley (Fig.8.10.3).
A seal (Fig.8.10.4) should be placed on top of the pulley before mounting.
