OPERATOR'S MANUAL Oscillating Spindle Sander OSS500 - Double Insulated EXTENSION CORD CAUTION When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords should be used.
