Page 14: Troubleshooting
Superabrasive User Manual Original Language Lavina® 20‐X 4/2015 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 specifications as the original ones. Never use lower quality or different type cord and plugs. In addition, take into consideration 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 can 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 are needed you have to replace all the cables with bigger gage rated cables for the length and amperage. 8.2 DISMOUNTING TOOL HOLDER TO CHANGING V‐RINGS AND FELT‐RINGS Figure 8.2.2 Figure 8.2.1 Figure 8.2.3 Figure 8.2.4 ... - Page 15 Superabrasive User Manual Original Language Lavina® 20‐X 4/2015 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 ...
