Superabrasive User Manual Original Language Lavina® 20‐S 6/2013 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 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® S 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 spiders 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.8.1 1) has to be firmly fixed to the unit. A gap seen there means that there are loose screws fixing the holder. The screws have to be tightened immediately for safe operation. Working with loose screws on the holder could also cause bad damages on the machine. Tightening force of the screws has to be 25...30N.m(18...22 ft/lbs). ... -

Superabrasive User Manual Original Language Lavina® 20‐S 6/2013 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 specifications as the original ones. Never use lower quality or different type cord and plugs. In addition, take into consideration is 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 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 needed you have replace all the cables with cables with bigger gage rated for the length and amperage. 9.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND SPIDERS, CHANGING V‐RINGS AND FELT‐RINGS Figure 9.2.1 Figure 9.2.3 Figure 9.2.2 Figure 9.2.6 ... -

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 Figure 9.5.10 tensioning device back in place and pull the belt from the roller on the right side (Fig. 9.5.5). Put Figure 9.5.10 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).
