Superabrasive User Manual Original Language Lavina® 25M‐S/ Lavina® 25M‐S‐HV 11/2014 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 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® 25M‐S‐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, and/or screws. Tool holders: Buffers and spiders are consumables and must be visually checked on a daily basis and replaced if needed. Make sure flanges or discs are secured well 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 a gap is seen here, it means that there are loose screws securing the holder. The screws have to be tightened immediately in order to safely operate the machine. Working with loose screws can also 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 that you check the screws on a regular basis (Fig.8.1, 2), that fix the Figure 8.1 “QuickChange” holder to the safety part, so that the holder will not fly away if the buffers get damaged. The “QuickChange” should be clean. The tension of the planetary belt can be checked by 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 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 with washers. CHECK EVERY 200 WORKING HOURS Every 200 hours, the operator should inspect all parts of the machine carefully. Most importantly, inspect and clean the tool plate connections, power cords, plugs, vacuum hoses, water tank, and filter. Also, check the water flow of the pump. Check the guard assembly. Make ...
Superabrasive User Manual Original Language Lavina® 25M‐S/ Lavina® 25M‐S‐HV 11/2014 9. TROUBLESHOOTING INDEX OF PROBLEMS AND SOLUTIONS 9.1 REPLACING POWER CORD AND PLUGS When replacing the power cords 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 application and the electrical source. The greater the distance, the greater the resistance and the less current that will be available at the end, there will be a voltage drop and the inverter will sign into alarm mode. This will also happen if there are several machines 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 then you have to replace all the cables with cables of a bigger gauge rated for 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 ...

Make 2 signs on the dismounted belt exactly 10 cm out of each other (belt without tension) (Fig.9.5.2). The purpose is to measure 10.2 cm on the belt in tension what is a tension of 2%., a maximum of 2.5% is allowed. ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DAMAGED AND IT WILL NEVER RECOVER 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 measure of 10 cm between the marks becomes 10.2 cm (Fig.9.5.7) (Fig.9.5.8). Tighten the tensioning device while turning the bolt move the planetary head so the belt can slide. (Fig.9.5.8). Do not forget to lock the tensioning device (Fig.9.5.9).
