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.

Page 13: Maintenance And Inspection
Superabrasive User Manual Original Language Lavina® 25‐X 3/2015 7. 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®X 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 elastic element 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.7.1‐1) 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 22‐25N.m (16‐18ft/lbs). It is very important to regularly check the screws that secure the “QuickChange” holder to the safety part (Fig.7.1‐ 2), so that the holder will not fly away if the buffers get damaged. The Figure 7.1 “QuickChange” should be clean also. CHECK EVERY 200 WORKING HOURS Every 200 working hours, the operator should inspect all parts of the machine carefully. Most importantly, inspect and clean the tool plate connections, power cord plugs, vacuum hoses and water tank and filter. Also, check the water flow of the pump. Check the guard assembly. Make certain the wheels are clean and rotate properly. Inspect the control buttons. If there are defective control parts, they should be replaced immediately. Figure 7.2 Replace worn vacuum and water hoses. ... -

Superabrasive User Manual Original Language Lavina® 25‐X 3/2015 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 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. 8.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGING V‐RINGS AND FELT‐RINGS Figure 8.2.2 Figure 8.2.3 Figure 8.2.4 Figure 8.2.1 ... - Page 16 Superabrasive User Manual Original Language Lavina® 25‐X 3/2015 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 Figure 8.3.9...
