OPERATION ■ Do not sand on one spot too long. The sander’s rapid action may remove too much material, making the surface uneven. Extended periods of sanding may tend to overheat the motor. If this occurs, turn off the sander and wait until the sanding disc comes to a complete stop. Then remove the sander from the workpiece. Remove your hand from the vent area, remove the sanding disc, then (with your hand removed from the vent area) turn on the sander and run it free, without a load, to cool the motor.
OPERATOR'S MANUAL RANDOM ORBIT SANDER RS280VS VARIABLE SPEED – 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.
