Each additional weight weighs about 64lbs 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 additional weights depend on the tools; it is not always possible to add 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.

Page 13: Maintenance And Inspection Cleaning
Superabrasive User Manual Original Language Lavina® 25LM‐S‐E 12/2014 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 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 bolts or screws. Tool holders: Buffers and spiders are consumables and must be visually checked every day and replaced when needed. Make sure flanges and discs are mounted and locked well in place. The key lock holders (butterflies) should be checked also. Check the rubber buffers and the fixing of the holdings. The flange holding the buffers (Fig8.1 1) has to be firmly fixed to the unit. A gap seen there means that there are loose screws securing the holder. The screws have to be tightened immediately to safely operate the machine. Working with loose screws on the holder could also cause damage to the machine. The tightening force of the screws has to be 25… 30N.m (18…22 ft/lbs). It is very important to regularly check the screws (Fig.8.1 2) that fix the “QuickChange” holder to the safety part, so that the holder will not fly away if the buffers get damaged. The tension of the planetary belt can be checked daily by moving the head and feeling the resistance of the Figure 8.1 moving pulleys, if the belt slips tension immediately, see the chapter: Troubleshooting. 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 for fast and easy control and correction of the belt. It is recommended that the tension of the belt be tested after the first 15 hours, and tightened if necessary. For the correct tension, see the chapter: TROUBLESHOOTING “mounting the belt”. Every time you open the control cover, mount all the screws back with washers. CHECK EVERY 200 WORKING HOURS Every 200 working hours, the operator should inspect all parts of the machine carefully. ... -

Page 15: Troubleshooting
Superabrasive User Manual Original Language Lavina® 25LM‐S‐E 12/2014 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 exact specifications as the original ones. Never use lower quality or different types of cords or plugs. In addition, take into consideration the distance of the application from the electrical source. The grater 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 go into alarm mode. This also happened if several machines are working on the same line or when the generator is underrated. In general, our standard cable can be doubled in length, if a longer length is needed you can replace all the cables with cables of a bigger gage rated for the length and the 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 place the buffers and the spiders, the tool holder has to be dismounted.

Make 2 marks on the dismounted belt that are exactly 10 cm from each other (belt without tension) (Fig.9.5.2). The purpose is to measure 10.2 cm on the belt in tension for 2% tension , a maximum of 2.5% is allowed (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).
