TOOLS AND ACCESSORIES WEIGHTS Superabrasive offers additional weights for increasing 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 weight stacks onto three posts that are around the outer bowl (Fig.5.2). The additional weights depend on the tools; it is not always possible to ass weights. Some tools work too aggressively and the machine can 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. Always use the key for mounting. Item number is A03.00.00.00 Figure 5.3 FOAM PLATE Diamond tools with Velcro are mounted on the foam plate 9“(Fig.5.4). The foam plate is mounted on the “QuickChange”System. Item number is LV‐9‐FP‐S Figure 5.4 SECURITY PLATE FOR QUICKCHANGE PADS Plate (Fig.5.5) used to ensure the “QuickChange” pads.

Superabrasive User Manual Original Language Lavina® 25L‐S/ Lavina® 25L‐S‐HV 6/2014 8. MAINTENANCE AND INSPECTION CLEANING Keep your machine clean. Cleaning the machine in 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® S 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 spiders 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.8.1‐1) 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 25‐30N.m (18‐22ft/lbs). It is very important to regularly check the screws that secure the “QuickChange” holder to the safety part (Fig.8.1‐ 2), so that the holder will not fly away if the buffers get damaged. The “QuickChange” should be clean also. The tension of the planetary belt can be checked by Figure 8.1 moving the main head and feeling the resistance of the moving pulleys, tighten the belt if necessary. CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS Check the belt tension after 15 hours of 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 that the belt tension be checked after the first 15 hours and tightened if necessary. For the correct tension, see TROUBLESHOOTING “mounting the belt”. Every time you open the control cover, mount back all the screws with washers. CHECK EVERY 200 WORKING HOURS ...

Superabrasive User Manual Original Language Lavina® 25L‐S/ Lavina® 25L‐S‐HV 6/2014 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 the same specifications as the original ones. Never use lower quality or different types of cords and plugs. In addition, take into consideration 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, there will be a voltage drop and the inverter will sign into alarm mode. This will 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 you need longer lengths then you must replace all the cables with cables of a bigger gauge rate for the length and amperage. 9.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND SPIDER, CHANGING V‐RINGS AND FELT‐RINGS Figure 9.2.2 Figure 9.2.3 Figure 9.2.1 Figure 9.2.6 Figure 9.2.4 Figure 9.2.5 To check or replace the buffers and the spiders, the tool holder has to be removed.

Make 2 signs on the dismounted belt that are exactly 10cm from each other (belt without tension) (Fig.9.5.2). The purpose is to measure 10.2 cm on the belt when tensioned. ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DAMAGED AND IT WILL NEVER RECOVER FROM ITS ORIGINAL TENSION Mount the belt back around the planetary pulley; see that the belt is behind the driving pulley (Fig.9.5.3). Put the belt around the left roller of the tensioning device (Fig.9.5.4). Put the tensioning device back in place and pull the belt from the roller on the right side (Fig.9.5.5). Put the belt around the driving pulley (Fig.9.5.6). Begin to tension until the previous 10cm measurement equals 10.2cm (Fig.9.5.7 and Fig.9.5.8). Tighten the tensioning device while turning the bolt and moving the planetary head so the belt can slide (Fig. 9.5.8). Do not forget to lock the tensioning device (Fig.9.5.9). 9.6 CHECKING THE TENSION OF THE BELT Figure 9.6.1 Figure 9.6.2 Figure 9.6.3 Figure 9.6.4...
