Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 4. OPERATION PRELIMINARY CONTROLS Inspect the working area as explained in the safety instructions. For wet use, fill the water tank with the electrical cable disconnected. Connect the vacuum extractor and ensure that the vacuum hose is clear and will easily follow the machine. Plug in the machine and make sure that the power cord is free to follow the working direction of the Lavina® X machine. WATER FLOW CONTROL UNIT The operator can direct water to be sprayed in the front (Fig.4.1) by positioning the lever in the horizontal position; the water will spray under the cover of the machine when the lever is in the vertical position (Fig.4.2). The flow regulating valve located on the tank (Fig.4.3) controls the water flow to the working area – in front of the machine or Figure 4.2 Figure 4.3 Figure 4.1 under the main head cover of the machine. ADJUSTING AND MOUNTING TOOLS The Holder A41 in LAVINA® X can work with either 3 or 6 buffers, which will alter its range of motion. You can make the change after dismounting the holder as per the instructions in TROUBLESHOOTING. In the Lavina 20‐X, 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. ... -
Page 10: Starting The Machine
Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 STARTING THE MACHINE First follow the directions in the chapter on Safety Devices and Safety Instructions. Next, release the emergency stop (12), turn the Ready switch (Fig. 4.6 9) to the ON position to put the machine in standby mode. Check the potentiometer (8), and ensure that it is set to the working speed. If working wet, add water to the floor surface. If working dry instead switch on the vacuum unit. Finally, hold the machine firmly and push the RUN button (11). 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. 4.2‐1) and periodically run the pump (fig. 4.10‐11) 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 your vacuum works properly 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 (10) . 2.Turn the ON/OFF (9) switch in position OFF, this will cut the voltage to the invertor and the green light will turn off. While working do not turn off directly from the READY switch or from the Emergency Stop, but follow the steps above. Use the Emergency button (12) only in an emergency. Remember not to hold the machine in one spot before turning off the motor. ALARM The Reset button (4) will light when the inverter goes into alarm mode. The most common failure is motor overload. To exit alarm mode, push the reset button (4). A code on the inverter’s display indicates the type of the alarm. When the same alarm is repeated several times, it is imperative to find and eliminate the cause of it, otherwise the inverter can become damaged. ... -

Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 5. TOOLS AND ACCESSORIES WEIGHTS Superabrasive offers additional weights used to increase the productivity of the machine (Fig.5.1). Each additional weight weighs about 64 lbs or 29kg. Each individual application, type and condition of surface, power capacity of the outlet, etc. will determine the number of weights you can use without tripping a breaker. The weights stack onto three posts fixed around the outer bowl (Fig.5.2). Additional weights will largely depend on the tools; it is not always possible to add weights. Some tools work too aggressively and will cause the machine to stop. The weight can be ordered with item number A08.00.00.00 Figure 5.1 Figure 5.2 TOOL HOLDER KEY The tool holder key (Fig.5.3) is used for adjusting, mounting and dismounting of the foam plates.

Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 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® X 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 elastic element 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.7.1‐1) has to be ... -

Page 16: Troubleshooting
Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 8.TROUBLESHOOTING INDEX OF PROBLEMS AND SOLUTIONS 8.1 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 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 can 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 are needed you have to replace all the cables with bigger gage rated cables for the length and amperage. 8.2 DISMOUNTING TOOL HOLDER TO CHANGING V‐RINGS AND FELT‐RINGS Figure 8.2.2 Figure 8.2.1 Figure 8.2.3 Figure 8.2.4 ... - Page 17 Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 Figure 8.3.2 Figure 8.3.3 Figure 8.3.1 Figure 8.3.6 Figure 8.3.4 Figure 8.3.5 Figure 8.3.7 Figure 8.3.8 ...

Put the belt around the left roller of the tensioner (Fig. 8.5.4). Put the tensioner back in place and pull the belt from the roller on the right side (Fig. 8.5.5). Put the belt around the driving pulley (Fig. 8.5.6). Begin to tension until the 10 cm between the marks stretches to 10.2 cm(Fig. 8.5.7) (Fig. 8.5.8). Rotate the head while tensioning to allow regular tension distribution along the belt. Tighten the tensioner by turning the bolt. Move the planetary head so the belt has freedom to move. (Fig.8.5.8). Do not forget to retighten the screws on the tensioner (Fig.8.5.9).

Page 21: Mounting The Belt
Superabrasive User Manual Original Language Lavina® 20N‐X 6/2017 Unscrew the bolts around the motor (Fig.8.7.10) and take the motor off (Fig.8.7.11). Detach the retaining shaft/bearing (Fig.8.7.12). Remove the filling ring (Fig.8.7.13). Now the motor base disc is free to be removed; however, the only way to displace it is to press it out on a bearing press (Fig.8.7.14) (Fig.8.7.15). Dismounting the driving pulley: take the top screw out to release the bushing (Fig.8.7.16), push up the bushing and washer together (Fig.8.7.17), push the washer down to separate them, and then remove the bushing (Fig.8.7.18). Pull out the key (Fig.8.7.19). This will release the washer. Remove it (Fig.8.7.20), dismount sealer cap (Fig.8.7.21). Now, dismount the pulley using two crowbars; do not use excessive force (Fig.8.7.22) (Fig.8.7.23). Push the sealer cap to dismount (Fig.8.7.24). When replacing the sealer cap, be sure to secure with sealant and center the holes to mount the pulley. Change the two other pulleys as earlier described. While the motor base is dismounted, roller units can also be changed easily. Unscrew the nut on top (Fig.8.7.25). The pulleys can be released with two crowbars; do not use excessive force Figure 8.7.26 Figure 8.7.25 Figure 8.7.27 (Fig.8.7.26) (Fig.8.7.27). 8.8 MOUNTING THE BELT Figure8.8.4 Figure 8.8.2... -
